TM4 was moved from the South Hot Cell to the Conditioning Station.

  375   Tuesday, June 04, 2013, 15:34 Bevan MossConditioning StationRepair  Relay replaced

ESC was called out again to inspect the chiller as it was showing the same problem as before. This time when started one fan came on (this is not what happened last time) but the fan controlled by the VFD did not. It was eventually traced to a relay that has been replaced. The system was tested as best it could without a load and appears to be working. It will be difficult to tell until a heat load is in place if the fix has solved everything.

High active water system is refilled. Air are drained out of  system before pump to be started. Following sequence are used to bring the whole system back to operation:

1. close ITE , open ITW. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITW.  Switch off pump when system pressure is stable above 100 psi.

2. Close ITW, open ITE. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITE. Switch off pump when system pressure is stable above 100psi.

3. Open ITW, Open ITE. Switch on pump. both ITW and ITE beam line related water circuits are in loop.  Switch  off pump when system pressure is stable above 100psi.

4. Close ITE open ITW.  Bring ITW  target module water circuits back to loop by connecting bypass fittings on to circuits. Only bring one circuit back to system at first. Switch on pump. Wait for system pressure stabilized. Then Close ITW. bring next circuit back  to system.  Open ITW .  wait for pressure stabilized.  repeat the process until all water circuit and connected with bypass fittings in ITW.

5. Check possible leak on valves, fittings, and flow sensors in ITW pit.

6. Go to electrical room, check all ITW water signal status.

7. Close ITW, Open ITE. Repeat same procedure as step 4 on ITE target module water circuits.

8. Check possible leak on valves, fittings and flow sensors in ITE pit.

9. Go to electrical room, check all ITE water signal status.

10. Open ITW.  At this stage, full ITE station and half of ITW station water circuits are in operation.  Check possible leak on pumps, valves, fittings, gauges on water station at TH west end.

11. Keep system in operation. Watch on - tank level , system pressure, and conductivity on resin circuit and whole system.

I reconnected the entrance module back to the ITE station. All diagnostic cables, turbo- pump, air lines, water lines on ITE entrance module and BL2A3 window are connected back.

ITE entrance module is reconnected in ITE.

  756   Wednesday, September 24, 2014, 15:16 David WangITEStandard OperationTM4Ta#44Reconnected TM4 in ITE.

TM4 has been reconnected back to ITE. I started all turbo pumps on ITE and TM4. The ITE TP4s was extremely difficult to start. This pump is new, and was replaced before  the last ITE beam time on July. After several times try and starting mode switch, it is started. Its temperature and current draw showed on controller and very good after the start. The current draw on ITE TP1s is  s a little bit high and unstable. I will keep watching on ITE TP1s. I think the ITE TP1s is close to the end of the pump life. Other pumps are good so far.  

  698   Wednesday, July 02, 2014, 14:29 David WangITEStandard Operation  Reconnected TM3 in ITE.

I reconnected TM3 in ITE. All turbo pumps have been started. The water supply to TM3 only in ITE. The HV keys are back to electrical room.

  1639   Tuesday, October 10, 2017, 10:45 David WangConditioning StationRepair  Re-route TCS water lines.

TCS  cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate.  New re-routed system is tested to 70KV without spark. No leak has been found on new lines after the test.

ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane water lines re-route folder.

  2158   Tuesday, October 27, 2020, 11:46 Matthew GareauNorth Hot-CellRepair  Ratcheting repair issues with both left and right master

 

The were issues with both left and right master ratcheting;

- the left handle was getting stuck in a close position when there was a higher ratcheting tension added

- the right ratcheting was not tightening preventing proper use of the manipulator


Chad and myself were able to identify a missing set screw for the tong cable.

Once this was added the issue with the left master ratcheting seems to be solved.


Lubricant was added to the left master ratchet and this seems to solve this problem as well.


There was also an observation of missing set screws on the spare manipulator for attaching the wrist to the ratcheting handle, which will need to be ordered and attached.

 

 

  


 

 

  1936   Monday, June 10, 2019, 08:26 Carla BabcockConditioning StationMaintenanceTM4No targetRamping voltage on TM4 w/o source tray

TM4 in conditioning station with no source tray, extraction electrode set to HV bias. Brought up to 30kV over the weekend by ISAC ops with no issues.

BIAS=30kV

EL=15kV

IG1=9.4e-7T

 

Monday, June 10, 2019, 08:21 : At 32.4kV on bias, EL at 15kV, bias sparked to EL. Every bump of 100V on bias is accompanied by a small vacuum jump and often by a small current increase from ~60uA to 120uA.

* Conditioning station read back and set values are off by 2kV but archive values show this has always been the case. Which to trust? *

Monday, June 10, 2019, 08:54 : Spark while sitting at 38kV on bias, 19kV on EL. Seems to be a spark to EL.  Sitting at 38kV for ~10mins

Monday, June 10, 2019, 09:32 : Sat at 40kV for ~10mins or so, bumping up again.

Monday, June 10, 2019, 09:38 : Spark to EL while sitting at BIAS / EL = 42kV / 20.5kV

 

Monday, June 10, 2019, 13:57 : Ramped to BIAS / EL = 43 / 21.2. No problems other than what seems to be the usual conditioning station stuff.

 Monday, June 10, 2019, 14:17  : Couple sparks on the way to 48kV, seems to be to the EL.

Monday, June 10, 2019, 14:36 : Up to BIAS/EL = 51/25.5 with no big problems. Will stay here for a couple mins

 

  1938   Monday, June 10, 2019, 16:22 Carla BabcockConditioning StationMaintenanceTM4No targetRamping V on TM4, no HV cover in TH

Ramped down the bias so David could remove the HV cover and lock out the target hall.

Ramped back up to BIAS / EL = 50kV / 26kV quickly with no sparks.

Monday, June 10, 2019, 15:35 : BIAS / EL = 52kV / 26kV

Monday, June 10, 2019, 15:45 : BIAS / EL = 54kV / 28.5kV. It seems that keeping the EL at 1/2 the bias voltage is right on the edge of what is acceptable - the HV seems to be sparking to the EL instead of to ground (either that or the EM interference from the sparks it producing a reaction in the EL...) I will run the EL higher and see if that helps.

Monday, June 10, 2019, 15:57 : Sat at 54kV for > 10mins, will continue up

Monday, June 10, 2019, 16:11 : At BIAS / EL = 55.8kV / 29kV got some sparks, some to EL and some to ground. Back at 55kV.

Monday, June 10, 2019, 16:24 : Sitting at 56kV for a couple mins

Monday, June 10, 2019, 16:37 : Sitting at 56.3kV bias, a spark tripped off the IG1S, which tripped the turbo and shut down all the HV. Back to zero!

 Following the helium pressure test Don attempted to connect to the RGA via the network. He was unable to do so. This scan was desired so a pre and post water scan could be compared to indicate if there was any leaking. It has been decided to carry on as the HV and HP tests are of greater importance. Don will continue to investigate the RGA. Travis inspected from the conditioning station roof and determined that the RGA is getting power.
