CTF 3 General Layout TL 1 (2006) Drive Beam Injector (2003) PETS Line 30 GHz source (2004) RF photoinjector test (2007 -2008) 30 GHz tests CR (beginning 2007) Delay Loop (2005) Drive Beam Accelerator (2004) CLEX (2007) TL 2 (end 2007) • The transfer line TL 1 has transported, in 2006, the drive beam from the Delay Loop (DL) to the Combiner Ring (CR), preserving its time structure. • The Combiner Ring CR, installed for March 2007, will perform frequency multiplication at 150 Me. V/c: 30 GHz mode: from 3 GHz to 15 GHz, and will increase the drive beam peak current from 7 A to 35 A. 12 GHz mode: from 3 GHz to 12 GHz, and will increase the drive beam peak current from 8 A to 32 A.

Conclusion ØTwo open questions for the beam diagnostics: 1) Number of BPI to be installed is under discussion (according to performance). 2) New Streak camera laboratory not yet available for the start-up in March. ØInstallation of the Combiner Ring and the extraction line will be completed for the end of February 2007. Ø Alignment and hardware tests (Vacuum, Power supplies, Diagnostics, …) will be completed for mid-March 2007. Ø The commissioning, with beam, should start 19 th March 2007.
