|
Spark between HV cover vertical mesh plate and HS 60KV bias connecting clamp 90degree angle at 55 KV on TM2 top. HV cover is removed to test above
55KV. The spark triggered TH and SHC ventilation secondary alarm. |

Monday, March 18, 2019, 07:23, David Wang, Conditioning Station, Repair, TM2, , TM2 window line helium test
|
New seals with a blank off cap are installed on TM2 window line water block. The seals are checked at TCS with 70 psi helium for 5 minutes
with LD at 0.0xE-9atm/cc.sec. No response on LD during test. Seals are good. |

Helium pressure test on TM2 all water circuits is done. 70 psi helium , 10 minutes test time. Leak detector :base leak rate 0.0XE-9 atm.cc/sec, base
pressure 0.0Xe-4torr. No any response on LD during the test. All TM2 water circuit are leak free. |

|
| TM1 shielding plates and their holding bolts are inspected. No corrosion. TM1 is located at TCS now. Both TP1 and TP2 are started. |

Monday, June 10, 2019, 08:26, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, Ramping 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 |
|
Monday, June 10, 2019, 16:22, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, Ramping 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, 18:12, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, Attempt to push bias > 56kV
|
Monday, June 10, 2019, 16:59 : TM4 back up to BIAS / EL = 56.1kV / 29.5kV
Monday, June 10, 2019, 17:14 : After 57kV on the bias, things seem to be getting sketchy. The EL voltage and current are a bit jumpy and stepping
that voltage up seems to produce a slight spike in the bias current. |
|
Wednesday, June 12, 2019, 08:56, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, More TM4 conditioning without source tray
|
The conditioning station was ramped down overnight and David ramped it back up this morning. Currently trying to get it to sit stable at something higher
than 55kV.
