• The transfer line TL1 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 MeV/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.

The vacuum chamber components should have a minimum contribution to the impedance of the ring

Aluminum alloy minimize the resistive wall effect.

Typical cross sections: 100 mm x 40 mm (dispersion regions) and 40 mm x 40 mm (non dispersive regions)

Conclusion

Two 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.

Installation of the Combiner Ring and the extraction line will be completed for the end of February 2007.

Alignment and hardware tests (Vacuum, Power supplies, Diagnostics, …) will be completed for mid-March 2007.

The commissioning, with beam, should start 19th March 2007.
