Vertical focusing from edge

Opera give less focusing strength than optical model

No face rotation

CERN initial: Less vert. focusing, more sector magnet,made QF obsolete (or changed to QF)

CERN final, LEGO blocks, flexible, ok, Octupole?

Beam Based Alignment Procedure:Select QP close to BPMDo orbit scan through QPModulate QP current (Producing additional kick, when beam not in center)Orbit with no orbit modulation when QP is modulated gives BPM offset

Can the QF used for vertical and horizontal plane?H-kick (0.2 mrad) Offset at QF: 2.0 mm 5% QF-Modulation: orbit change: 0.5 mm V-kick (0.2 mrad) Offset at QF: 1.5 mm 5% QF-Modulation: orbit change: 0.4 mm

10% QD modulation: orbit change 0.1 mm

Conclusion: BBA works with QF in horizontal and vertical planeNo individual PS needed for QD for BBA

Power Supply Procurement

Cost of magnet system allows to purchase complete PS-package in framework of CESSMAg

CERN resumes PS package

Change in concept

(Before: QP-PS in series, Purchasing as complete package turn-key from Industry)

Now: QP-PS in series, PSI-Controller, Voltage-source, DCCT; Assembling at CERN

Advantage: Better performance in respect of:

Maintenance

Adjustment of Beta-Beat

Beam-Based Alignment

Integration of Insertion-devices

Cost: More manpower needed for development and assembling

Concept endorsed by Review-Committee (J.F.Bouteille, R.Kunzi, R.Visintini, F.Bouvet)

Combined/Individual QP-PS and Air Conditioning-Limits

Pro Combined Pro Individual

Less expensive invest & operation Easier to repair (exchange)

*): 2 QF in series, cable length reduced to 60 m

Conclusion: AC is compatible with Individual powered QF/QDTAC 2013 Reporting back E.Huttel

CERN: a revision of the installed cooling capacity is recommended.SESAME: The capacities of SESAME have to be accepted (cost- limited).
