Thursday, August 15, 2013, 09:32, chad fisher, South Hot-Cell, Repair, TM3, , TM3 source tray installation status
|
The installation of the module side water block jig has been successful.
During initial attempts yesterday afternoon, installation of the jig proved, as expected to be extremely difficult. This was primarily due a poorly position water block from a previous repair were the soldering jig had not been used to position the block; specifically coil 1. This is the same block that contributed with the difficulties in removing the old source tray.
I was able to utilize the water block polishing tools as handles to reposition this water block ( as well as another slightly difficult one) into its location in the water block jig.
Please be aware, as the jig was very difficult to install, it will be very difficult to remove later (as it was when removing the old source tray).

Spark on HV only at 25.5, couple sparks from here to 33, then at 33 starts real conditioning.
EL is reacting to some of the sparks, not sure if this is just electrical noise or not.
Saturday, April 27, 2024, 18:14 :
lots of trips above 60kV on the set pt. tripping off turbos and gauges. IG2 needed the controller reset.
RESULT: Got to 64.5 (actual) 62 (set point) with quite a bit of sparking over 60kV. Will go the rest of the way to 73 in the next days. Data dumped as isac/data/TM3_HVtests_Apr272024.dat
Sunday, April 28, 2024, 11:23 :
Ramped back up to 60kV reasonably easily, couple sparks and turbo trips.
Went up to 64kV (set point) with a lot of difficulty. Data dumped as isac/data/TM3_HVtests_Apr282024.dat
Monday, April 29, 2024, 14:58 :
Ramped up to set pt 62 easily, went down to 500V then 100V steps after that.
Went to set pt of 67 and left it there for ~40mins. Not perfectly stable but not too bad.
Tuesday, April 30, 2024, 17:12 :
After rebooting the TCS PLC to fix all the non-responsive devices, everything is working fine again.
Ramped easily to 60kV in 1kV steps.
Still got to 67 without too much trouble. Behaving pretty well...
At 70.2 (set pt, 71.3 readback) the water and vacuum gauge both tripped off and cannot be restarted. I am not sure what the real power supply reading is here but in the past it has been 70.5 set pt = 73 real value, which is as high as the power supply goes.
Stopping here since I'm not sure the water is circulating... the off pump says it is and the on pump says its not... left it at 70.2 for 40mins, still sparking going on (20:28 to 21:10)
Data dumped as isac/data/TM3_HVtests_Apr302024.dat
Sunday, May 05, 2024, 10:50 :
Containment box and target installed.
HV conditioning starting at 47kV.
Spark at 58kV knocked out IG1. Continuing with IG2 and IG1S.
Went up to set point of 63, readback 64. Will continue on Monday.
Data dumped: isac/data/TM3_HVtests_May52024.dat
Monday, May 06, 2024, 09:37 :
Ramping system back up.
First sparks at 50kv while raising the EL voltage (not sure if they are related).
AS: Voltage quickly up to 63 kV from 49 kV. Very smooth, no sparks or instabilities. Ramped at around 250 V steps every 10-20 seconds. First signs of instability at ~62.75 kV and definitely at 63 kV. I guess this is where it was conditioned to last. Let sit at 63 kV for a while while doing something else. It sparked once and turned off a turbo after half an hour. Starting ramping again.
AS: Spark at 65.75 kV killed IG1. Carla manually reset at 69 kV. Still working. A spark at 70.25 kV took out IG1 again.
AS: Maximum voltage reached at about 16:45. Setpoint 70.5 kV, readback 71.7 kV, PS itself ~73 kV. Carla reset IG1.
AS: 18:30, spent about 1.5 hours cumulatively at this maximum voltage. During this time it sparked about 15 times. Not long enough to tell if the spark frequency is decreasing. In the middle of this, Carla did something accidentally and caused the voltage to drop a bunch, so I manually set it to 0 V. She then reset TP1S, which was not staying on. Also, the EE and EL stayed at their respective voltages during this downtime (2 kV and 28.7 kV). I ramped the main BIAS voltage back up to the maximum voltage within 5 minutes and it was smooth all the way but sparked again at the maximum voltage. It seems conditioned up to or near the max voltage. Ramped down and turned off BIAS, EL, and EE.
AS: Dumped data to isac/data/TM3_HVtests_May62024_Alexander.dat
Tuesday, May 07, 2024, 10:02 :
Tested the EE - ramped up easily to 7kV, but then had issues maintaining the voltage. No vacuum response. Ramped down since we never use it that high anyway, though cable should be good for 10kV. More investigations later.

|
Tuesday, January 02, 2024, 15:58 :
Started HV ramp up on TM3 service tray about 3pm today. Had to bypass TCS:BIAS interlocks to make it work - there are some flow restrictions on the water lines that are causing the flow interlock to periodically trigger. The water flow it not very important for this test as long as the water is moving. Turned out that it was also conveninent to have all the interlocks bypassed because sparks tripped off the IG1 gauge and this did not cause the HV bias supply to turn off. Should use same setup next time.
Some sparking around 35-44kV, tripped off turbos/IG1/IG1S 3 times and so decided to ramp down.
Tried again while standing outside TH door to hear if sparking is outside the vacuum. Went to 48kV very slowy with multiple trips of the turbos, mostly TP2. Lots of sparks but easy to ramp back up to previous high point, so likely just a painful conditioning process. Current draw 167uA at 48kV. No sparks audible outside door, and vacuum response looks too large to be electrical noise.
Continued on Wednesday January 03 - went up to 53kV in the same way as before, lots of TP2 trips making its current a bit unstable... data was dumped as TM3_servicetray_conditioning_jan32023. Tried limiting the current on the power supply to very near the drain current to see if that reduces the number of trips. Didn't notice a significant effect.
Thursday, January 04, 2024, 09:57 :
Restarting conditioning, starting at 180uA at 53kV. Got up to around 60kV with many trips of the turbos, and one restart of the IG1 controller needed. Added a grounding hook to the vacuum controller rack to see if that helps reduce the trips. (doesnt appear to have).
Friday, January 05, 2024, 09:51 :
Continuing conditioning. Starting by sitting at 50kV for 10mins. No sparks observed during this time.
Even though we got to 60kV last time, onset of conditioning started at 58.6kV with a trip at 58.9kV... got up to 70kV.
Got to 72kV on Monday January 08 2024.
On Monday Jan. 15, tried to improve the grounding on the vacuum services rack to reduce sparking through the turbo controllers. Added two welding cables from the vacuum rack ground busbar to the copper grounding strip on the ground. If the spark is travelling from the faraday cage to the rack through conduit or grounding cables, maybe this will help. If it is coming through the turbo cable then it likely won't. Tried to add grounding straps on the turbo controller chassis (there is a brass screw which I think is for this purpose) but couldn't get either of the screws out with any resonable force. They undo a bit then get stuck...
Wednesday, January 17, 2024, 20:39:
David vented TM3 with N, then opened the service cap to install new insulators. We pumped back down and Alexander and I ramped back up today - instabilities started around 55kV and we were back to slow conditioning in the high 50s. Got up to a set point of 65kV. Ray did some work on the TCS bias supply and now neither the set point or readback is correct. The PSU was reading 51.5kV at set point 50kV and 60kV at set point 58kV. Will continue later...
Wednesday, January 31, 2024, 16:23
Ramped up again, some slight instabiities around 56kV but could still go up pretty quick until about 65kV. Since Ray's testing of the TCS:BIAS supply both the readback and the set point are off from the powersupply display. Ran out of time and ramped down at set point 70.5.

stopped at 69.4
Wednesday, February 07, 2024, 15:28 :
Ramped easily to 60kV set point and let it sit there. Didn't spark at all then after 100mins, sparked TP2 off. Otherwise first sparking happened at set point 67.
Found at limit at around 72.5 on the PSU front output, set point 70.6. think it comes from EPICS. Will have to test the power supply.... stopped there.
Thursday, February 08, 2024, 15:03 :
Long term testing. ramped back up, first spark at set point 65.
Let it sit for 2hrs 20mins. Something like 6 sparks during this time. Current also dropped significantly from 0.32A to 0.27A.

|
David Wang and I did the service cap inspection in target hall: see WP I2015-10-06-10.<br>
Signs of sparking were seen underneath 3 insulators: E ("Cavity"), A ("Oven+") and B ("Oven -") at the pair water lines coming out of the feed-through and going to the HV chase. Specifically one water line of E is very close to the feed-through insulator (2-3mm gap) and here the sparking sings are more prominent: see picture. |
