1. CARE SC meeting August 2005 T. Garvey JRA1 – SRF (WP 7 – 11)

2. Task 1. Proto-type couplers 4 couplers of type TTF-V ordered last quarter 4 couplers of type TW60 ordered in July – delivery time is one year. Thermal simulations being performed as requested by ISAC using ANSYS – paid for with EU funds.

3. Task 2. Titanium-nitride coating bench Estimated cost for “sputter” system is 150 k€ !

4. Task 3. Conditioning studies Processing TTF-III couplers. Experience gained will be used for Proto-type conditioning.

5. Budget for 2004 and 2005 already overspent – but can’t be validated. Schedule of WP7

6. WP – 8 TUNERS UMI Tuner –Many piezo-electric types characterised. Choice made. Tuner proto-types being manufactured by Zanon. Delivery expected October. Magnetostrictive tuner –Analysis of magnetostrictive rods performed. Good option for frequency compensation. Detailed tests delayed, awaiting cryostat insert. CEA Tuner –Two tuners received in June. Mechanical modifications to be made before tests. Piezo electronics developed. Full system to be tested on C45 cavity in CryHoLab. IPNO activities –piezo-electric actuators characterised at low temperature, radiation hardness tests performed, RT measurement of resonant spectrum as function of pre-load force……..

7. WP – 9 Low Level RF Task 9.1.1 Transient detector – on schedule –Automated and remotely controlled measuring system designed, assembled and tested. Task 9.1.2 LLRF automation – on schedule –FSM for RF power station implemented as DOOCS server – prepared and tested Task 9.2.1 Cost and Reliability – no news Task 9.2.2 Radiation damage studies – on schedule. –RadMon installed and operating routinely.
