Ramping up HV to ~30kV, encountered problems and had to drop back to 28kV. No response on IG1 or anything else during sparks. Lots of charging-type behaviour on the bias current. Protons at 55uA

Tuesday, September 17, 2019, 02:02 : 15 mins with only 1 spark at 30kV so increased the bias

Tuesday, September 17, 2019, 02:31 : 32kV. Current unstable

Tuesday, September 17, 2019, 02:41 : Current continues extremely unstable but not much sparking....

Tuesday, September 17, 2019, 02:53 : Proton beam trip initially settled the bias current down, but then current began climbing pretty steeply with protons still off

Tuesday, September 17, 2019, 03:28 : Protons dropped to 40uA from 55uA, Bias current is much more stable and no sparks for 25mins

Tuesday, September 17, 2019, 03:36 : Raising voltage easy to about 33.5kV then instability and sparking similar to around 31kV at 55uA p+

Tuesday, September 17, 2019, 04:45 : Lowered protons to 25uA and no sparks though the current is not stable

More things but forgot to write them down. Spreadsheet attached.

  1255   Tuesday, June 07, 2016, 11:42 David WangSouth Hot-CellStandard OperationTM4Ta#47electrical check on TM4 with old Ta target at SHC.

I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good.    See attachment

I wrote all OL to 0  in attachment 1 ohmmeter check. Please See attachment 2 for correction.

I did an electrical check on TM1 at CS. The resistance check:A-B 3.918m ohm, A-C 5.905m ohm,A-D 4.070m ohm,B-C5.462m ohm,B-D3.633m ohm. They are very close to the check we did in SHC. The only unusual thing I found during the check is the ohmmeter reading between A and 60 KV common (6.2K )and the Megga reading between them  at 250 V which is 0. I repeated 4 times and always got the same readings. However, after so many times check, the Megga reading between A and 60KV   suddenly went back to normal(300 M at 250V) at the final check.  And,it stays at 300M now.  All other measurements are same as we did at SHC before.
