3 CTF3 collaboration meeting 2007 G.Geschonke Status
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/
INFN Power supplies: CERN RF deflectors: INFN Septa: CIEMAT MoU not signed yetKicker: CIEMAT/CERN pulser: CIEMAT/CERN 3 GHz source: CERN Controls: CERN BPM electronics: LAPP / CERN Vacuum chamber + BPM: INFN
MoU not signed yet
If the expected contributions will be provided, the Combiner Ring will be built to schedule

c) Installation of : Combiner Ring and Transfer Line TL1
TL1 installed, commissioned with beam,Combiner Ring injection region commissioned,
Combiner Ring installation:all magnets, septa, kicker installed,vacuum chambers and beam diagnostics will be installed before March 2007

Improvements
Big effort to improve operational reliability
water temperature stability for RF pulse compression:new system gives stability within ± 0.02 degrees !
automatic system for 3 GHz conditioning, as well as 30 GHz operation for CLIC structure copnditioning/testing
supervision from CCC now possible
Beam dynamics studies:Emittance measurements,better understanding of the machine: model fits machine

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
21 CTF3 collaboration meeting 2007 G.Geschonke Status
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
