Chad and I leak checked TM4 HS line after new target is installed yesterday. No leak has been found. Also, I helium pressurized the HS line at TCS this morning. TM4 HS line is good on this test. The TM4 gas line configuration on TM4 top is leak check as well. No problem.

Thursday, October 19, 2017, 14:20: EE configured for conditioning. HV cage locked up

Thursday, October 19, 2017, 16:46: BIAS / EL / EE at 45 / 22.5 / 0 kV

Thursday, October 19, 2017, 17:16: 30 min without sparking. Lowering to 0. Continue conditioning tomorrow.

Friday, October 20, 2017, 08:22: Resuming HV conditioning

Friday, October 20, 2017, 08:44:  BIAS / EL / EE at 45 / 22.5 / 0 kV

Friday, October 20, 2017, 09:48: No sparking. Continue conditionoing

Friday, October 20, 2017, 10:40: BIAS / EL / EE at 50 / 22.5 / 0 kV

Friday, October 20, 2017, 11:30: HV spark (at 52.5 kV) tripped TP2 and TP1s resulting in IG1S and power supplies tripping.

Friday, October 20, 2017, 13:50: Gelo is troubleshooting flickering on/off of ANODE, TGHT and TBHT power supplies.

Friday, October 20, 2017, 13:51: BIAS / EL / EE at 50 / 25 / 0 kV

Friday, October 20, 2017, 14:26: BIAS / EL / EE at 55 / 28 / 0 kV

Friday, October 20, 2017, 14:37: TP2 tripped on spark

Friday, October 20, 2017, 14:51: Gelo has determined there is a communication problem with the PLC on the HV platform. Troubleshooting continues.

Friday, October 20, 2017, 19:02: Troubleshooting did not succeed. Not able to control power supplies. Troubleshooting continue on Monday.

Monday, October 23, 2017, 09:00: After starting the TCS again today communication has been reestablished. Started heater conditioning.

Monday, October 23, 2017, 14:03: Heater ramping previously aborted and ramp down started due to ongoing PLC communication issues. TGHT and TBHT power supplies tripped on timeout around 13:45. Gelo will continue the troubleshooting.

Monday, October 23, 2017, 19:55: Switching off source after operating for 5 hours without any communication glitches detected (fiber optic communication cables swapped between HV platform and BIAS/EZL PLCs)

 After extensive troubleshooting the communication fiber was found to be damaged and has been replaced by Gelo.

The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak.  It was helium pressurized at TCS this morning. Leak rat:2.5 XE-7 atm.c/sec. The result  is same as last time check. No concern.

TCS vacuum system and water system have been started as well. Everything looks fine.

Thursday, November 09, 2017, 10:40: BIAS / EL to 30 / 15 kV. 400 uA on BIAS

Bias was stable for 1 hour. Handed over to RIB ops for heater conditioning.

Shielding plug is installed onto TCS. TCS is being pumped down to keep it under vacuum for the rest of the year.

 Dakine is on site to do maintenance on the chiller. The tech requested the chiller to operate.

Powered down mechanical pumps in ISAC-I Experimental hall, vacuum gauge and turbo pump controllers in ISAC-I B2 North Hot Cell service area

Tuesday, January 02, 2018, 14:45: TP1S started

Tested all 3 compressors and MP2

TCS:IG1S is reporting vacuum levels that seem to be too low (1E-10 to 1E-8 Torr). The gauge was connected to the controller for IG1, which showed the same value. A degas was performed for ~5 min.

I stopped TCS vacuum pumps for coming TM3 move.

TM3 turbo-pumps are started at TCS. We will keep pumps running until next Wednesday.

All TCS and TM3  vacuum pumps are started successfully.

Tm1 has been moved to TCS this morning. All turbo-pumps are started successfully at TCS and TM1.

TCS and Tm1 vacuum pumps are switched off this morning. TM1 TP1and TP2 work fine during this test period. Tm1 will be moved back to silo this morning.

TM1 IG1 stopped work during the test period. It could be broken. We will only replace this gauge if TM1 is used in ITW again.

 TM#4 was moved to the conditioning station from the south hot cell. The module was moved with out the containment box.

  Helium pressure test on TM4  water lines is done this morning. 70 psi helim , 1 minutes time to each circle. The result:

A(oven+): 0.00xE-9 atm.cc/sec

B(Oven -): 8.1Xe-7 atm.cc/sec

C(tube -): 0.00xE-9 atm.cc/sec

D(tube+): 1.0xE-5 atm.cc/sec

PQ(coil 2): capped on top. water lines were removed because of leak

RU(Coil1): 0.00xE-9 atm.cc/sec

EE: 0.00xE-9 atm.cc/sec

MSP: 0.00xE-9 atm.cc/sec

HS: No target, capped on top. It was fine on last target check in 2017 Oct.

window: Capped on top. Containment box is not installed.

The leak check on D line caused the IG1 small response during test.

B and D circle are double checked. The reasults are same.

D line leak is in E-5 atm.cc/sec range. It is possible to locate it by using helium spray method in SHC. The containment box is not on so it should be easy to do it.

Switch on IGA gauge at TCS and apply helium and water at certain psi to check the IGA response may give us more information on these leaks.

 All lines were test in last year shut down. They were good.

BIAS only. Water lines looped on top. Containment box off.
