1. INTRODUCTION

1.1. Genera.l

In order to extend tho oxperiaontnl facilities of tho 28 GoV -

CERN - Proton - Synchrotron,and to increase tho nunbor of experiaontal

beans, a further nunbor of quadrupole nagnots is required.

The quadrupole nagnots described in this specification shall

produce nagnetic fields with a uniforn gradient for the focusing of

beans of charged particles. Since the nagnots will be suppliod with

direct current, their no.gnetic circuits can be nado of solid stool blocks.

1. 2. Types of Quo.drupolos i Main Pnranctors

(see Gonernl assonbly drawing)

In tho final stage, thoro will bo different sizes of quadrupolcs

figuring as typos A, B etc., having tho sane cross-section of the core

and the coils, but different lengths. As they arc natched for oquo.l coi1

resistance, they present different nunbors of turns and different

profiles of copper conductors. Their nain paranoters are given in the

following table.

The no.in drawings, as listed on Pago 3, arc attached at the end of

the specification.

1.3. Scope of the Tonder

It is understood tha,t tho contr8.ctor shall mo.nufo.cturo, test and

dulivor to CERN, Moyrin, tho quadrupole magnets completely assembled

according to tho present specification. All equipment for monitoring

tho temperature and flovv of tho cooling water, tho protective covers

etc., must be supplied ond mounted by tho mo.nufacturor, so tho.t after

delivery tho magnets arc ready for immediate service.

Tenders do not include tho m::i.i1ufn.cturo of o.ny pnrt of the

supporting base, which will bo ordorod scpo.ro.tely by CERN.

1. 4. Access to Informo.tion and Tests

It is demanded that CERN be informed about all technical details

of tho construction o.nd of any subcontracting. Tho contractor must

supply throe complete sots of fabrication drawings, for internal use

at CERN,

CEilN also demands tho right of access to the factory during tho

fabrication nnd to have a roprosento.tivc present o.t all tests described

in this specification.

1. 5 Guarantee

Tho attached drawings arc tho result of an initial study. Tho

manufacturer is entirely responsible for his design and must guo.ro.ntoo

for o. fo.ultloss construction of tho mngnot.

Ono yoo.r after acceptance, o.11 aho.racteristics must still moot

the present specification.

Tho formal nccepto.nco of tho magnets will be postponed until they

have boon excited to full magnetic field and their po.rnmotors measured

o.t CERN. This testing shnll take plo.co within throe months o.ftor

delivery of the complete order.

1. 6. Deli very

CERN is interested in o. short delivery time, such o.s 8 ••• 10

months for tho first mo.gnat, after tho date of order.

2. MAGNETIC CIRCUIT

2 .1. Moclmic o.l Construction ( see drawing of the core)

Tho mo.gnotic circuit is composod of four polo blocks, whoroo.t

co.ch upper o.nd lowor po.ir forms ono sopo.rntc magnetic flux po.th. Tho

different po.rts nro kept together with countersink bolts o.nd positioned

by monns of side plo.tos o.nd pins, so tho.t tho quo.drupolos co.n be

o.ssomblod with tho required stability o.nd precision, in o. reproducible

way, and to olimino.to doformo.tions of tho go.p due to mo.gnotic forces.

For lntor alignment purposes, neo.r each end, on top of tho magnet,

a high precision roforonco support must be mounted, which will bo

delivered by CERN. (soc drawing o.tto.chod)

To obto.in tho required uniformity of tho magnetic field gradient,

tho following tolerances must be strictly adhered to, in addition to

those given on tho drawings.

Tolerances

a) The polo-faces, comprised between P o.nd n, must be finished with a

surface quality of o.bout 1.6 µ, (R = 1.6 #o, according to ISO­

Sto.ndo.rds).

b) The pole profiles, comprised between P o.nd R, must coincide with

tho indico.tod contour within~ 0.05 mm.

c) Longitudinally, corresponding points of tho profile must lie on

straight ·linoo within + 0.05 mm.

d) The end surfaces of the poles must be perpendicular to tho

longitudinnl centre plo.no to.:!::. 0.3°.

o) After assemblage, tho two dinmoters between opposite polo tips

must be 100 + O.l mm, and everywhere along-tho axis they must not

differ from co.ch other by more thnn O.l mm.

f) After o.ssomblo.gc, at any tro.nsvorso.l cross-section, tho position

of tho four polo faces relative to co.ch other, i.e. the aperture

PS/6605

- 7 -

symmetry, must bo nccurato to± 0.05 ma or± 0.02°, whichGvor is

smaller. Therefore, for co.ch single polG block, tho position

(nnglcs o.nd dista.noos) of tho polo profile rolo.tivo to tho outer

surfo.ccs towo.rds tho magnetic circuit, o.nd tho precision of.tho

side plntos, must be verified o.ccordingly before nssomblo.go.

g) Loco.l o.ir go.ps, if m1y, botwoon tho different joints of pole blocks

ond side plntcs must not exceed 0.05 mm.

h) After o.ssomblo.gc, the four distances between tho edges P nnd R of

ndjncont polos must bo equnl within 0.05 rrun, ncnr ca.ch end of a.

quo.drupolo. A compa.rntor or micrometer must bo employed, ho.ving

specially shnpod o.nvils for these moasuraments.

i) Tho reference supports must be positioned with tho following

accuracy:

Their bo.sos must bo pnrallol to tho horizontal symmetry pla.no

within 0.01 mm, nnd o.t tho ratod distance to + 0.02 mm.

Tho contra lines of their bores must cross within + 0.02 mm of

tho mo.gnat contra line.

Tho lon&itudinnl distance from one support to the other,

monsurod between their boro centre lines, must bo within

+ O.l mm.

Inspection

Before o.ssomblo.go, all po.rts of tho magnetic circuit will bo

inspected by a roprosonto.tivo of CERN, ond the gap dimensions chocked

after tho mngnot hns boon nssomblcd without coils. About suitable

methods nnd mcnsuring equipment shall be discussed later, but in

principle tho mnnufncturor must supply tho instruments ns tomplo.tos,

micrometers, optico.l devices etc., required for this oxnmination.

Moreover it must bo proved tha.t tho assembly cnn be mo.do in a.

reproducible wo.y, so that the dimensions of tho finished qundrupolos

- 8 -

nro tho samo ns domonstrntod without coils.

Finish

Except for tho gap surfaces, which must be protected by an agreed

rust provontntive only, tho whole mngnot must be painted with nt least

one coat of priming and two finishing coats of an ono.mel to bo soloctod

in agroomont with CERN.

2.2. Mngnetic Properties of t h o Stool

Tho magnetic circuit must be made of annealed low cnrbon stool,

forged or laminated, having for example tho following composition:

0.05 o/o C

0.02 o/o P

O.l o/o Si

0.02 o/o S

O.l o/o Mn

Cr. Ni trncos

Tho coercive force of tho stool must be smallor thnn 2 A/cm, and

tho flux density for an excitation of 300 A/cm nust oxcood 20 400 Gauss.

Tho manufacturer must supply nt least one sample of onch stool

butch of which tho magnets will bo made. To conform to our existing

npparntus, tho sa.mplos must be properly machined rings having an

inner diruneter of 76 .±. 0.1 mn, outer dionotcr of 114 + 0.1 nm nnd n

width of 15 + 0.1 nm.

Tho samples will be measured at CERN nnd must satisfy tho

specification as detailed nbovo. CERN reserves tho right to reject

magnets presenting inhomogeneities of tho mngnetic field, caused 'by

defects in tho iron body (roforonco is made to section 1.5 nbout iho

formal ncceptnnco).

In tho event of irresolvable disputes concerning tho results of

magnetic moasuromonts, a neutral institution will bo asked to arbitrate.

3. EXCITATION COILS

3.1. Genero.l (sec dro.wing of the coil)

The winding is composed of four singlo pole coils, which nre

fixed .to the yoke by ne0,ns of clo.mps.

Temporo.ture gro.dionts due to wo.tor cooling and magnetic forces

subject the coils to honvy mechanical stresses.

The mnnufo.cturor nust o.ssumo complete responsibility tho.t the

coils will sntisfy o.11 roquirenonts for tho tests described horonfter,

and o.ssuro undisturbed safe operation la.sting for yea.rs.

3.2. Conductor Mo.tcrio.l ond Dinensions

The conductors must be made . of electrolytic copper having a -8 0 resistivity inferior to 1.76 • 10 Ohl~.m at 20 c. Preference should

be given to the so-called OHFC-type, freo from go.s, which co.n bo

brazed without difficulty.

'Tho cross-section of the conductors is o. roctnngle with slightly

rounded corners and o. contro.l cooling duct. It l'J.ust have tho follqwing

ThG manufacturer must guarantee that the resistance of the

finished magnets docs pot oxceGd 0.19 Ohm, at room temperature.

All brazings must be carried out with great care. No joints

between conductors inside of a layer are admitted. All joints,

inside and outside thG coils, must be absolutely watertight and not

increase appreciably tho electrical resistance. The manufacturer

is entirely responsible that no.obstruction nor leakage may over

years of magnet operation occur.

The manufacturer must submit a few samples of tho copper and of

all particular sorts of brazing connections to be employed.

3.3. Construction and insulation of the coils

The coils consist of completely mou1ded blocks. The coil sides

aro placed under 90° into the cross-like air gap. Tho coil end

connections must bo bent outwards sufficiently, so as not to reduce

the width of the gap aperture. All coils are electrically connected

in series.

The coils arc cooled by four parallel water circuits (i.e. one

layer per circuit) for type A quadrupoles.

ln..gene.ra:;L, tP.E:1 inlet tcmpe)'.'ature of the cooling water will be

above tho dewpoint of tho surrounding atmosphere, but occasionally

it may be as low as 10° c, so that the coils can be completely

saturated with water condensed from the atmosphere. It is therefore

important, that the insulation be guaranteed watertight, to avoid

short circuits under these circumstances.

- 11 -

Tho mo.xinum temporaturo riso of the cooling wntor being a.s high

ns 50° c, tho difference of thormnl oxpunsion between o.djo.cont

conductors would ,'IBJ.ount to 1 ••• 2 mi~, if thoy could movo frooly. Tho

coil must bo constructed in such n way nnd tho insulntion must be

sufficiently strong o.nd cletstic, tho.t oven n lo.rgc nunbor of thorrrml

cycles will not co.use cro.clrn in tho insulo.tion.

Tho insulo.tion for the individuo.l conductors o.nd the mo.ss­

insulo.tion for the pole coils nust be built up with to.pas consisting

of glo.ss o.nd integro.ted nico... No othor mo.teric..ls (i. c. cotton, nico.

foils, etc.) o.re o.dmitted. The to.pas nust be of tho typo specially

treated in order to obtnin a good ndhosion to epoxy resins. For the

so.me reason the conductor must be co.refully cloo.nod with acetone or o.

similar solvent irmodio.tely before tho insulating process.

All pnrts of the coil must be inprognatod under vo.cuui~1. Tho

choice of tho epoxy rosin mid details of the inpregnation procedure

aro tho responsibility of tho nnnufncturor. In principle, it is also

perl'.li ttod to omploy opoxy pro-i:r:1pregnated tapos, which do not

necessarily imply a further vo.cuun treo.tnont, but o.doquato rnoo.suros

must bo undertaken to obtain o. quo.lity o.s high as by proper vacuun

inpregno.tion.

Before the construction of tho coils co.n be stnrtod, the

mo.nufacturcr must subni t CL few sn.:r:1ples of the insulation to be

employod, mo.de on conductors of conparo.blo sizo. After tho.t, o. proto­

type coil rmst bo no.de, which shnll be subjected to an o.ccelero.tod

o.geing test (thermal cycling). It is undorstood tho.t this prototype

coil is not used for tho no.gnats n.ftorwo.rds.

Therno.l cycling of tho prototype coil nust be perforncd na

follows:

Tho coil is supplied n.t nonino.l current nnd so:newho.t reduced ro.to of

cooling water. A tenporo.ture nonitor, plncod on tho wn.ter outlet,

reo.cts when o. pro-selected tel'.lporo.ture is roo.ched, reversing the

- 12 -

direction of water flow and intcrruptinG tho current. After n certo.in

dclo.y the current is reset, until the so.mo temperature rise -occurs in

the opposite wo.y; tho tomporo.ture noni tor reacts o.gain, etc. After

every 200 revorenls (i.e. 100 complete inverted cycles) with succeeding

tenpero.turc rises of 0 T = l0°c, 20°0, 30°c, 40°0 and 50°0, tho coil

insulation must be tested as given under 3.6. b) and 3.6. c) (electrical

tests).

Tho prototype coil will be considered satisfactory, when after

the 500 thermal cycles it still withstands tho olectrico.l tests and

shows no shearing of tho conductors. If the prototype coil is a

failure, tho mnnufo.cturer must improve its design o.nd construct n new

prototype, until o. so.tisfa.ctory solution has been found •. Only after

this can the serio.l production of tho rno.gnets be startocl.

The connections between the coils nro mo.de with copper bars,

adequately insulated fron the yoke. To conform to the existing cnbles,

the main terminals must bo made exo.ctly o.s indicated on the drawings.

3. 4. Cooling and thermo.l J;lrotection

Epoxy- or rubber insulated copper tubes, lend out to the main

water manifolds, which must be mo.de of copper or sto.inloss stool. Tho

copper tubes a.re insulated from the manifolds by neans of intermediate

rubber hoses which a.re fitted with usuo.l hose-clips.

All bro.zings must be carried out with groo.t co.re. The

manufacturer is entirely responsible that no obstruction nor leakage

may occur even o.ftor prolonged mo.gnat operation. Possibly, no solder

requiring o.n additional brazing flux should be employed.

Since deminornlized water will be used, all raetnllic po.rts-of tho

cooling system must be made of copper, sto.inloss stool or bronze. By

way of exception corta.in stnndnrc1 parts r:.mdo of ordinary brnss o.ro

admitted, e.g. tho main water couplings.

PS/6605

- 13 -

Tho maximum pressure of tho cooling water will be 25 atm., and

the maximum outlet temperaturo 9 for a nominal rise of 40° C will be

80° c. The cooling system must bo suitable for continuous operation

under those conditions.

Tho whole cooling system must be oloctrically insulated from

tho iron yoke. Thoroforo 9 it is indicated to mount all accessories

as tho instruments, tho main terminals otc. 9 on a common insulating

panel, fixed on the frontal side of the magnet.

A list of CERN standard parts is given in section 4. 5.. All

instruments 9 described in tho following chapters and some other

items must be purchased accordingly.

Tho main inlet and outlet water couplings aro standard. Before

entering the manifolds the water passes through a standard filter

with apertures smaller than 0.5 mm.

To monitor the inlet pressure a manometer having a range of

1 ••• 25 atm. must be used with a pair of insulating auxiliary

contacts which open whenever tho pressure is out of a certain

adjustable range (minimum and maximum settings).

-To monitor the outlet temperature a thermometer having a range

of 0 ••• 100° C must be used with a pair of insulated auxiliary

contacts which open whenever tho temperature is out of a certain

adjustable range (minimum and maximum settings: minimum setting

used for freezing alarm).

Near each end of individual water circuits or on the joint hot

outlets for two circuits, small temperature sensors must bo mounted,

provided with-auxiliary contacts which open, whenever tho temperature 0 reaches 90 ••• 95 c. To improve the heat transmission it is desirable

to make tho insulation between the sensors and tho conductor as thin as

- 14 -

possible. However, it :oust still withstand tho high voltage test

described hereafter. All tenperature sensors nust be wired to a central

terminal-strip, where they are connected in series.

It is suggested to use the stnndard 11Microthern11 ele:oents,.but

other :t:1.akes of' oonpo.ro.ble characteristics Bo.y be also accepto.ble.

All above interlock contacts and sone other devices (emergency

stop button, signal la:op relay, etc.) must be connected to a standard

r.ml tiple plug, part of a central control box mounted near the electrical /

main terminals.

3.5. Leak and Flow Tests

a) Leak tests of the conductor bars

The water tightness of the conductor bars, as delivered

by their manufacturer, :oust be proved. Therefore, each

conductor bar nust be pressurized to 60 atn. (with air

under water or water only). Conductor bars which show

any evidence of a leak must be rejected.

b) Leak tests of the joints

It is essential to verify that all brazing connections

within tho conductor (if any) o.nd the bro.zings between

adjacent water circuits are absolutely watertight,

before they are insulated. Therefore, they :oust be

pressurized irJ.rJ.odio.toly after the br.~zing operation to

60 atn. (with air under water or water only).

c ) Leak and flow tests of the finished coil

The finished coils (unpainted) will be inspected by a

represontativ·e of CERN. Tho flow in each water circuit

for a pressure drop of 5 o.tn. r.mst bci measured. It•

should be essentially oquo.l for equivalent circuits and

exceed 1.8 l/nin. for type A quadrupoles.

- 15 -

Tho finished coilsriust bo prGssuri~od to

40 atm., for 10 minutes (with nir under water, or water

only). No evidence of a lenk must appear.

d) Leak test of tho finishod mn.gne t

The whole cooling systen of tho finished magnet must be

pressurized with water to 30 ntn.,for 10 nir.utes. It

must bo absolutely watort The manometers must be

disconnected during this test, in order to prevent

possible dnmo.go due to overload.

3.6. Electrical tests

After the hydraulic test specified under c), tho finished coils

must be prepared for tho succeeding electrical tests.

a) Thermal cycling (sample test)

b)

CERN reserves tho right to select who.tovor coils to be

tested with 50 non-inverted cycles, as follows:

The . coil nust be energized until o. temperature rise of 0 45 ••• 50 C is reached. Aftor this, the current must be

interrupted and tho wo.··~or flow no.intained. Aft·'.)r the · coil

ho.s cooled off, it must be energized again, and so on.

This cycling can be perforoed by neuns of currents smaller

than nonino.l, but the distribution of the water flow nust

be the so.no as the final one. Theroo.l cycling must be

mo.de not before 0:1e week after the inpregno.tion. After the

cycles the insulation nust not show any cracks o.nd further­

nore satisfy the following high voltage tests.

Conductor-to - ground insulation I

After 6 ••• 12 hours submersion under water at a.r.ibicnt

temperature the coils nust be lifted out and wrapped into

- 16 -

wet cloths,. used o.s o.rtificinl ground. A test vol to.go

of 5 kV rms. o.t 50 cps. must be o.ppliod between the

coils o.nd ground for one ninute. Tho resisto.nco

a.go.inst ground, which must be tho s~me before ond o.fter

the high voltage test, rmst be moo.sured with n voltage

of nt lea.st 1 kV d.c.

c) Inter-turn insulation

Immediately o.ftor tho high voltage test o. voltage of

100 V rns. per turn nust be induced to the coils, for

one ninute. For this test the coils should be used o.s

the secondary of o. trnnsforner o.t o. frequency of sone

hundred · cps. Tho prino.ry current o.nd the induced

voltage oust not vary during the whole test period.

The nanufo.cturor no.y propose a. different nethod to

detect inter-turn short-circuits.

d) Electrica.l tests of tho finished ne.@e t

The conpletely o.ssenbled no.gnet will be inspected o.s

follows:

A test voltage of 5 kV rns. o.t 50 cps. nust be

applied between the coil ond tho iron body, for

one ninute. The resistance a.go.inst ground which

nust be the so.no before and after this test, aust

be neo.surod with o. voltngo of nt loo.st 1 kV d.c.

The circuit of tho tenpero.ture sensors nust be

tested with o. voltage of 2.5 kV rns., for one

ninute a.go.inst the coil o.nd for one ninuto o.gninst

the iron body. The so.no o.pplie_s for the inter lo ck

circuits.

The wiring of the interlock syston nust be checked.

- 17 -

Tho rosistanco of tho coil nust be verified. It

nust not exceed 0.19 Ohn, nea.sured botwoon the

no.in terninnls, nt roan tonpero.ture.

The o.bovc tests perforncd o.t tho final inspection o.t tho factory,

will be repented o.fter reception o.t CERN •. The nain test voltages will

be reduced to 80 o/o for this second test.

3.7. Mounting and Mccho.nico.l Protection of tho Coil

Tho winding nust be carofully fixed to tho iron body, so tho.t

nechnnical forces co.used by tho fringing field of tho no.gnet cannot

do.no.go nny po.rt of it. The coils nust be fo.stened to the yokes by

nenns of insulated clo.nps.

Adjacent to the coil sides, rubber shoots nust be inserted, so

that tho coils fit tight to the yokes nnd clnnps.

On both ends of the r.mgnct renovo.blo protective co.ps nust be

nounted enclosing the coil o.nd o.11 other wo.tor o.nd electrical devices.

They should be r.mde of fibre-glo.ss of a.t loo.st 5 rm thickness and of o.
