1 ESLS 04 Daresbury Laboratory
SRS Status The RF system The performance of the SRS Recent upgrades Upgrades planned Conclusion Andrew Moss ESLS 04 Daresbury Laboratory

2 ESLS 04 Daresbury Laboratory
The SRS machine 600MeV Booster 12MeV LINAC 5MeV Gun 2GeV Storage Ring Andrew Moss ESLS 04 Daresbury Laboratory

3 ESLS 04 Daresbury Laboratory
RF System Andrew Moss ESLS 04 Daresbury Laboratory

4 ESLS 04 Daresbury Laboratory
KSU 86 modules up to 700V 9amp to make 50KV 3 – 5 KHz operating frequency 100KHz module cycling Closed cubicle with air conditioning 4 modules redundancy Andrew Moss ESLS 04 Daresbury Laboratory

5 ESLS 04 Daresbury Laboratory
KSU fire December 03 50% of control fibres, 5 PSM modules System repaired in 2 days (with manufacturer help) Smoke/arc detectors needed in sealed cabinets ! Cause = loose electrical connection (after 16 months operation !) Andrew Moss ESLS 04 Daresbury Laboratory

6 ESLS 04 Daresbury Laboratory
KSU faults A second burning incident occurred Aug 04 after a shutdown Caused by demin water ingress Canal cooling causes problems KSU 99% up time Andrew Moss ESLS 04 Daresbury Laboratory

7 ESLS 04 Daresbury Laboratory
RF Cavity April 04 Cavity 1 window failed First window failure for 20 years Cause unknown but signs of Mulitpactor on every ramp of the machine for last year Andrew Moss ESLS 04 Daresbury Laboratory

8 ESLS 04 Daresbury Laboratory
Cavity window Andrew Moss ESLS 04 Daresbury Laboratory

9 ESLS 04 Daresbury Laboratory
Cavity 1 Decision taken to run with 3 cavities Waveguide blanked off Tuner parked at zero and disconnected Andrew Moss ESLS 04 Daresbury Laboratory

10 ESLS 04 Daresbury Laboratory
Waterload fitted Successful operation Parked cavity transparent to the beam Max RF system power 200KW = 240mA Andrew Moss ESLS 04 Daresbury Laboratory

11 ESLS 04 Daresbury Laboratory
Impedance display 50 Ohm Load Andrew Moss ESLS 04 Daresbury Laboratory

12 ESLS 04 Daresbury Laboratory
Waterload failure 300KW waterload in place of Cavity 1 fails after 3 months operation Loads re-configured Cause = RF joint not tight in high field area Andrew Moss ESLS 04 Daresbury Laboratory

13 ESLS 04 Daresbury Laboratory
RF system changes ? Decision to remove cavity1 under discussion Hybrid power splitter 4.7dB 1.2MV total needed for SRS Less machine impedance Investigation needed Andrew Moss ESLS 04 Daresbury Laboratory

14 ESLS 04 Daresbury Laboratory
3 IOT scenario Change Klystron – 3 IOT’s Would have to be cheaper than new klystron Eliminate cavity crosstalk Andrew Moss ESLS 04 Daresbury Laboratory

15 ESLS 04 Daresbury Laboratory
Current SRS Status 2GeV 250mA, currently limited to 180mA 30hr lifetimes, 40 minutes to refill 95% availability, most months ! Andrew Moss ESLS 04 Daresbury Laboratory

16 ESLS 04 Daresbury Laboratory
SRS Status Machine not gas limited ? Lifetime issues limiting current since start up 09/04 Unstable operation at high currents, RF system dependant Possible HOM ? RF phase issues 15Hr Andrew Moss ESLS 04 Daresbury Laboratory

17 ESLS 04 Daresbury Laboratory
SRS performance 2003/4 Operating hours up by 1600 to 5224 Operating efficiency up 6% to 93% Mean Time Between Failures up by 54% Mean Time To Recover down by 20% Biggest change = KSU operation Andrew Moss ESLS 04 Daresbury Laboratory

18 ESLS 04 Daresbury Laboratory
Recent upgrades Linac drive RF 400W 3GHz 4uS amplifier replacing drive Klystron Gun RF 200W 500MHz 1uS amplifier replacing : - Andrew Moss ESLS 04 Daresbury Laboratory

19 ESLS 04 Daresbury Laboratory
Future upgrades Bergos beam loss monitors installed every straight. starting Oct 04 New Bergos BPM system updates at 5Hz Vertical Polarisation Undulator in straight 5 Oct 04 under user control EPICS voltage feedback for RF system Andrew Moss ESLS 04 Daresbury Laboratory

20 ESLS 04 Daresbury Laboratory
Conclusion In general SRS performing well for a 24 year old machine Many upgrades done and still to be done RF system very reliable since KSU installed Cavity 1 issue to be resolved SRS to continue operating for how long ? Andrew Moss ESLS 04 Daresbury Laboratory
