In order to cure the vertical instabilities, two new (3 GHz)

RF deflectors (in Al) have been designed by LNF (Frascati) and

are under construction.

RF deflectors CR. HDS 0150 & CR.HDS 1050

They are foreseen:- to be at CERN end of June, - to be tested with RF power beginning of July, - to be installed in the machine later on

CLEX hardware tests

1) Tests of power supplies (81 in total) 30 power supplies tested and operational

6 power supplies not tested (ripple, water leak, not connected to magnets)

45 power supplies for correctors not yet arrived at CERN

Remote control not yet OK for several devices

2) Polarity tests Done on all standard magnets

Found 10 wrong polarities

All dipolar correctors remain to be done

PHIN RF gun expected next week at CERN

and laser beam still under development

Conclusion

Installation into the Injector, Drive Beam Linac, Delay Loop, Transfer Line TL1 and Combiner Ring => OK

Installation of the Transfer Line TL2 connected to the Combiner Ring for the end of June 2008 but:

- Indian dipole magnets ?

- Power supplies for dipolar correctors ?

Installation into CLEX (Phase 0) will be finished for the end of June 2008 but:

- Laser for CALIFES ?


Conclusion (con't)

Installation into CTF2 for the photo-injector

- LAL proposed help during week 25 (Monday 16th June 2008)

- However this week is foreseen to be dedicated full time for 30 GHz

- Hardware tests for PO and CO not yet in the Schedule

- Installation expected to be finished for the end of August

- Tests with beam could take place in October 2008 during the installation of the Tail Clipper into the TL2 line.

- Strong request from CARE to finalize the test as deliverable for EU-FP6-JRA-PHIN
