1 2014/3/25TTC Meeting 2014@DESY1 Beam Operation Experience at Quantum Beam Project in STF Kirk

2 2014/3/25TTC Meeting 2014@DESY2 No change during “beam” operation in KEK-STF even after many earthquakes!! The answer is… MHI-12 and -13 were very stable in Quantum beam experiment

3 2014/3/25TTC Meeting 2014@DESY3 We have a few examples for change in Cryomodule test But….

4 superconducting rf test facility History of Cavity Performance in KEK-STF  Vertical Test in CW mode  Cryomodule Test in Pulsed mode

5 5STF Cavity Group Meeting (2013/5/13) Status of RF Conditioning for MHI-12 600μsec 1500μsec

6 6STF Cavity Group Meeting (2013/5/13) Status of RF Conditioning for MHI-12 1500μsec

7 7STF Cavity Group Meeting (2013/5/13) Status of RF Conditioning for MHI-12 600μsec 1500μsec

8 8STF Cavity Group Meeting (2013/5/13) Status of RF Conditioning for MHI-12 1500μsec

9 Comparison of Radiation Level History MHI-12MHI-13 The radiation level was never changed during the CM test.

10 2014/3/25TTC Meeting 2014@DESY10 Cavity performance degraded by “Earthquake” during beam operation?

12 2014/3/25TTC Meeting 2014@DESY12 Log Trend in 12/Oct/2012 MHI-12MHI-13

13 2014/3/25TTC Meeting 2014@DESY13 Log Trend in 24/Oct/2012 MHI-12MHI-13

14 2014/3/25TTC Meeting 2014@DESY14 Log Trend in 31/Oct/2012 MHI-12MHI-13

15 2014/3/25TTC Meeting 2014@DESY15 Log Trend in 7/Dec/2012 MHI-12MHI-13

16 2014/3/25TTC Meeting 2014@DESY16 After these earthquakes, the cavity performance was never changed!!

17 Cavity Performance for STF-2 2014/3/25TTC Meeting 2014@DESY17

18 In future… The high power test in STF-2 will start from 2015. 2014/3/25TTC Meeting 2014@DESY18
