Cryogenics: ~100% availability over 2 months, then problems (4 CB stops + incident)

Vacuum: in range of 10-11 mbar Cold alignment: ~1.2 mm vertical offset corrected Cavity conditioning OK, only CAV2 has FE Cavity tuning OK: all cavities at 101.28 MHz, mid range Cavity performance: 6 MV/m/CAV with less than 50 W Serious issue with power coupler identified Solenoid performance: OK, “feature” under control Combined powering cavities and solenoid OK Static heat load measured within specs ( ~ 10 W) LLRF loops working well beyond specs at 2 MV/m

Issues for phase 1: RF coupler

9

Observation: RF drifts when driving cavities at high power to initially assumed operational bandwidths thermal effects in the power coupler

Potential showstopper

Actions taken:

• Dedicated test in SM18 permanent damage at 200 W• Post mortem analysis• Second test in SM18 OK after 9 hours at 60 W• Test bench at room temperature: no damage with 500 W

for 1 hour, or 250 W for 24 hours• Third test in SM18 week 36, testing possible fix• Adapting low level RF loops to reduce bandwidth as much

as possible (now 3 Hz 50 W seemed possible)• On Saturday 29th August, CAV4 powered at 14 W

(minimum requirement for operation) for 24 h clear signatures of degradation!

80 W !

Adapting the LLRF (D. Valuch et al.)

16

• On 13/09/2015 all five cavities were successfully powered and locked using an automatic sequence

• Relatively stable operation at 2.5MV/m with 3Hz bandwidth• Field quality in per-cent/degree mode. Worse than the specification, with sufficient

power we can do much better. • rms power limited to ~20W, saturation set to 40W• Coupler gets damaged at 80W for 24 hours.

Page 17: HIE-ISOLDE Project Status Report Yacine KADI CERN HIE-ISOLDE Project

Adapting the LLRF (D. Valuch et al.)

17

Microphonics is the limiting factor for low power operation

Low frequency vibrations (1-5Hz), higher frequency vibration (50Hz) in the cryostat not yet understood

Perturbations are seriously affecting the cavity field – operation at high field (>3MV/m) without tightly locked loops is not possible

Cavity 4 coupler collapsed, but cavity operational at >3Hz bandwidth => Field limitation

Cavity 5 coupler motor is not fully operational – bandwidth can not be set to more than 2Hz

Page 18: HIE-ISOLDE Project Status Report Yacine KADI CERN HIE-ISOLDE Project

Adapting the LLRF: next steps (D. Valuch et al.)

18

Localize the source of vibrations Measure the microphonics in Generator Mode Switch off pumps and other equipment, 10-15 minute cycle time

Deploy new firmware and FESA class to address minor bugs Implement automatic cavity sequence (new FESA class) Start preparing the OP interaction (MachineSetpoint property)

Attempt to lock all cavities at higher than 2.5MV/m (yield 6MV/m): Need to increase the power limit, otherwise not possible. Closely monitor the Forward power for deposited heat

Cryolab Test Set-up (T. Koettig)

19

First cool-down is planned for this MondayThe goal is to measure the temperature distribution along the coax cable and coupler antenna first w/o RF powerThen start powering with stepwise increase in RF power until we see a thermal runawayTest set-up will be used also to qualify new RF coupler assembly

Overall Summary• Enormous progress since April 2015

• Infrastructure in place• HEBT hardware commissioning completed• CM1 installed, cooled and powered. Full test campaign carried out• REX beam commissioning well advanced • Beam commissioning of SC Linac is possible in September

• The results of hardware tests (problem on RF couplers) highlighted that CM1 is not fully qualified for sustained operation as planned

• Agree with Collaboration on a common scope for 2015 Physics run
