Monday, June 22, 2015, 08:57 : Stopped turbos

Monday, June 22, 2015, 13:02: Venting. Had to bypass interlocks as IV4 is timed out.

When turned ON it was not going higher than 3.6A (EPICS/front panel). Kazuya checked the connections at the back and also the EPICS/PLC/PS input/output signals. He compared these values with the similar once of the TSH:TBHT PS (which is also a Xantrex PS 10-600). E-Fault 6275

It turned out to be the connections on the top of the ion source box: the target heater was not connected and the power supply was not seeing the load. Tomorrow we'll check all the top connections, with the corresponding power supplies.

Wednesday, January 31, 2018, 09:50: A wire (B - F) was too close (Almost touching) to the EZL and had visible sparks during HV tests 1 & 2. The wire was adjusted to sit higher. and away from the EZL

Due to high vacuum a leak check will be done on the system. Thursday, July 19, 2012, 09:00 : Base leak rate 4E-9 atm-cc/sec Thursday, July 19, 2012, 09:07: Leak detected on side door. Mid 1E-8 range. Thursday, July 19, 2012, 09:08: Leak detected on front door. Mid 1E-6 range. Main leak left or bottom side. Thursday, July 19, 2012, 09:20: Leak on side door could not be reproduced. Previous response possibly due to  "cross-talk" with front door.

Replaced grid containing ring (target side) with new ring. No contact between target and anode measured in lab. NOTE: While closing up the VCR fittings the tube rotated causing the tube to flatten in a bend. This may reduce water flow on the heat shield circuit.

 Thursday, July 05, 2012, 08:39: Water supply open. Vacuum stable at 5.9E-7. Due to the kink in the heat shield cooling line, flow in the heat shield line is lower than other lines (visually inspecting speed of paddle wheels).

The vacuum on TSGIG1 reads 2.85e-07. Turing on water on teststand and observing any changes in vacuum pressure.

Thursday, September 13, 2012, 08:16: Opened up cooling water. Vacuum (IG1) increased from 5.9E-7 to 6.2E-7 before returning to 5.9E-7. Similar response on IG6 (valve closed). Response is however similar to previous (short time ~5 min) vacuum fluctuations.

IG1 has been spiking randomly, causing everything to turn off. Looks like the water leak is still there.

AS - Multiple purges done on RP1 & the backing lines. Some water noted. FS#3 is closed.

 Fault: 13334

Tuesday, July 28, 2020, 12:00: Leak discovered in ISAC Test Stand MB1 PS. Appears to be coming from hose barb soldered connection to heat sink of pass bank. Pass bank will need to be disassembled and heat sink soldered on a workbench.

Determined on Friday April 16th that the water leak was on the coil negative circuit. This was determined by circulating water through once circuit at the time. Only HF and GE tested (not Extraction Electrode).

Fault: 12797
WP: C2019-10-23-2

ISAC test stand power supply MB-1 leak.

Water can be seen underneath and behind power supply cabinet. Repairs as per WP.

Friday, October 25, 2019: Power supply operational. AM

 The Swagelok fitting on the return side of the flow sensor for the HS circuit was tightened to stop the leak. See e-fault 8650

See Cyclotron e-fault 6637

Tuesday, April 09, 2013:

 Water leak has been repaired, but P/S could not be turned on. Ground interlock still latched. The base of the cabinet was filled with water - most of the water could be scooped out with a bucket.

Wednesday, April 10, 2013:

Removed the remaining water in the P/S rack.
