• T1 is composed by 2 arms• Each arm is composed by 5 planes• Each plane is composed by 6 CSC

trapezoidal chambers• Each chamber is composed by 1

anode and 2 cathode planes• For mechanical reasons, each arm

is divided into two halves : each half is considered independent from the other also from electrical/logical point of view

• In total, each halve include 15 chambers

Saverio MINUTOLI

Summary





Saverio MINUTOLI

Requests (1)


The committee recommends contacting the CMS integration office for a ground point onto YE2, YE3, and perhaps onto the HF platform. Dmitry should be involved since this is rather a mechanical issue.

I propose to drill the threaded holes on inner radial surface of "YE4 inner disks" with 30 mm offset from its edge. The holes should be on 3 o'clock and 9 o'clock for both EndCaps. (Dmitry)

Each ¼ T1 have a main grounding ribbon running the length of the support frame. The ribbon is copper, 200 microns thick and approximately 10 cm wide. (also by Sergei)

Exteriors of CSCs connected with copper foil (also by Sergei)

In addition the aluminum support structure electrical continuity have been reinforced with copper braid or thick wires.

Saverio MINUTOLI

Requests (1)


Cavern GROUND Main grounding ribbon

CSC ground reinforced

Frame joints reinforced

Boards support grounding

Saverio MINUTOLI

Requests (2)


The committee endorses the insertion of fuses to protect 1.5mm2 power cables between the LV power supply and the 6th frame. It is important to explore the failure modes with the inline fuses in conjunction with remote sensing. Consider to add remote monitoring of the fuses for trouble shooting. Make sure that any additional work on the – side gets into the site planning.

Request of installing fuses on each electronics card triggered a complete redesign of the LV distribution on the detector.

Two x 4 LV distribution boxes (on T1 and at the MARATON output)

New cables on YE3 to connect the LV boxes

One fuse on each line at the MARATON output. Status of fuses is available locally and remotely through DCS.

One x 4 LVsense box (at the MARATON input)

Additional work on –side already planned within the schedule.

Saverio MINUTOLI

Requests (2) “Panels and Cables”


Fuse Box Front view Fuse Box Rear view

New LV cables

New 6th frame LV Distribution Box

¼ T1 internal LV and Vsense cabling

Saverio MINUTOLI

Requests (2) “Remote monitoring”


Fuse ROC_TOP blownAll ROC Fuses OK ROCs 2V5 Main power OFF

DOHM Fuse OK DOHM 2V5 Main power OFFFuse DOHM blown

By means of an optoMOS, the information on the status of each of the fuses is stored in digital format, optically isolated from the DCS system. The three fuse status bits for each ROC plane, plus the ON/OFF status of the main voltage, are fed to an R-2R ladder network.

Saverio MINUTOLI

Requests (2) “Vsense redundancy”


Vsense Box

Added Low Voltage sense redundancy in order to avoid Slow Control Ring break due to the master ROC failure.

Saverio MINUTOLI

Requests (2) “Vsense behavior in failure mode”


OVP = 4V

OVP = 3.3V

OVP = 2.9V

Saverio MINUTOLI

Requests (2) “Vsense behavior in failure mode”


Can be forced to zero by SW 5ms.

Saverio MINUTOLI

Requests (3)


Verify with the manufacturer that the flat cable crimp quality is qualified for power distribution of the foreseen levels.

The CSORVEM company (www.csorvem.it ISO9001) has confirmed that all its products are tested both mechanically and electrically within the limits of the characteristics of the components.

Automatic and semi-automatic crimping machines and more than 40 different tools/die sets available.

In our case Dielectric strength contact to contact of 500V and Current rating of 1.2A@20˚C for the Erni SMC type B connector.

In our case Voltage rating of 50V and Current rating of 300mA considering a section of wire 0.050mm2 (6A@1mm2) for the flat cable.

The manufacturer confirms that the crimp quality is qualified for power distribution of the foreseen levels.

Saverio MINUTOLI

Requests (4)


The Committee endorses the plan for shielding of the flat cables to the chambers.

All digital flat cables were removed from the detector and shielded with copper tape (35μm) welded at its overlapped ends.

The shield was protected by an insulation braid. The shield was connected to the metallic cover of the ROC (source) by

means of wire soldered to the cable shield on one side and a terminal lug to the other.

Shielded cables

Installation test and infrastructure


CHECKS on the system are foreseen when in the cavern

They are programmed in the last phases of installation:

Before insertion in the end cap

After the insertion in the end cap and before moving HF on

4 risers

The system check needs the LV, HV, R/O and DCS/DSS

connections.

This in turns requires:

DCS running

Power for LV racks

S4 F05 (rectifiers) EXD 20/55 (breakers)

Power in TOTEM racks

S2 B03 (HV) S2 B02 (DCS)

DAQ-Data DAQ-Trigger

Saverio MINUTOLI

Installation test and infrastructure


Schedule and assignment of manpower finalized

Presence of key people from CMS and TOTEM for the

installation is defined.

Availability of manpower confirmed :

CERN, INFN, and availability of FSU

The work to be completed before installation is on

schedule

Saverio MINUTOLI

Conclusions


Commissioning of the 4 quarters had been extensively done on the H8 beam in the past months.

Both hardware and software checked and functional.

Transport of 2 quarters to IP5 planned for the beginning of

December (7-10)

The other two quarters will preferably be transported beginning of

January (7-8)

We are ready for installation

Thank you for your attention.
