2.  High Power RF Systems (352 MHZ - 12 GHz)  High Efficiency Power Sources  High Voltage Systems  High Gradient Accelerating Structures

3.  36 persons  9 status FELL DOCT PJAS STAFF VISC COAS ADMI DOCT TRN  14 nations Scotland Italy Russia Holland Spain Germany Swizerland France Belgium Japan Finland Hungary Greece Pakistan a big THANK YOU to everyone !!!

5. HV connectors repair campaign (>100) New crowbar systems Replacement of obsolete equipment (e.g. Tetrode):R&D in progress New arc detectors (License agreement signed with an external company) Control system upgrade Reliability is a key issue here

6. Diet plans: http://www.eatingwell.com/nutrition_health/weight_loss

7.  Installation: equipment, waveguides, water cooling, local cabling  LEP equipment: 20 – 30 year old!, CW klystrons now being pulsed  6 HPRF units fully commissioned / on schedule  Reliability is a key issue here

8. 3 post phase tuner 352MHz, 1.5 MW peak WR 2300, L = 1500 mm, r1=70mm, r2 = 40mm VSWR ≈ 1.2 [depth 0 -> 100 mm] S 11 ≤ -30 dB [depth 0 -> 90 mm] Range: ≈ max 60˚

9.  CTF3 maintenance, upgrade & operation : 11 S Band and 1 L Band power sources Complexe waveguide systems HV system upgrade (thyratron replacement by solid state devices)  Plateform for experiments

10.  Experimental demonstration of the: deceleration process beam dymanic issues power production in PETS power transfer to accelerating structures main beam acceleration => high gradients

11.  Beam dynamics studies completed  Gun and buncher prototypes being constructed

12. Zone with welding defect Thales Electron Devices: 10 beam multi beam klystrons 77 % efficiency calculated Toshiba: 6 beam multi beam klystrons 75 % efficiency calculated Delivery and test in 2016 Development of a very high efficiency L-band multi-beam klystron with industry 1 GHz, 20 MW, 150 ms, 50 Hz, > 70% efficiency

13. TD26R05CC

14. Zone with welding defect Our range:  100 MV/m CLIC  50 MV/m low-β proton therapy linacs State-of-the-acceleration:  Normal conducting:  ≈30 MV/m SwissFEL  Superconducting:  31.5 MV/m ILC  LHC < 8MV/m Not only for CLIC !

16. 222 mm  Production of RF accelerating structures is very challenging  It comprises subsequent steps and quality analysis control

17. TD26R05CC  Full-fledged CLIC accelerating structure TD26R05CC build by CERN is successfully processed in XBOX1 up to 107 MW/m at 250 ns pulses
