Next steps: 2006 (shown at last collaboration meeting)

• Fully commission Delay Loop - done

• Separate Linac from rest of machine -done

• 30 GHz power testing -done

• Construction of CLEX building - started

• Install and commission Combiner Ring - ongoing

Combiner Ring and TL1:Optics: INFN Magnets: BINP/CERN/Lure/CIEMAT/

Install equipment in CLEX from May 2007

Install TL2: Finish optics, detailed layout produce all vacuum elements produce magnets, power convertersVery ambitious, spill over into 2008 ?


12 GHz

Decision to change CLIC structure development from 30 GHz to 12 GHz

For 30 GHz: bunch repetition frequency in Linac: 1.5 GHz increase by x2 in DL x5 in CR 15 GHzFor 12 GHz: bunch repetition frequency in Linac: 1.5 GHz increase by x2 in DL x4 in CR 12 GHz

small circumference change in CR can be accomplished with wiggler

no effect on hardware

30 GHz structure programme continues for the moment 12 GHz PETS in TBL 12 GHz PETS and accelerating structures in Two Beam Test Stand

smaller nominal beam current: can be increased by higher current in linac and higher RF power (shorter pulse)

Effect on CTF3:

Conclusion

Highly motivated team, excellent collaboration between all partners

Programme almost on schedule

• Commissioned up to including TL1 and CR injection• Combiner Ring to be completed in 2007, • TL2 in 2007 (?)• CLEX : many components covered by collaboration some still missing

Already demonstrated:

• full Beam Loading operation of linac• Phase coding of bunches• Bunch Interleaving in Delay Loop


Meeting Objectives

Define some open questions:

BPM / BPI: electronics TBL diagnostics – monitor + read-out

PETS TBL: Advance on tank design

Open topics not covered: TBL RF + other diagnostics - discussions with EPFL started, analog front-end ?TBL series components: quadrupoles, PETS, diagnosticsMachine protectionRadiation monitoring
