David Wang | Spent Target Vault | Maintenance | | UCx #34 | Repackage of UCx #34in NHC. |
UCX34# in pail 258(Vault lot 7C) has been repacked today. It is an investigation to find a possible leak source of radioactive Iodine in vault. The new pail number is 268. It is back to vault 7c . I wrote down the information in log book. The job is smooth today. I retrieved UCx 34 old pail and liner to TH. The liner from UCx#34 only has 3000 counts. I bagged it. It could be used later. However, the pail has 500K counts contamination on bottom outside rim. It may accidently be slided out of plastic bag and touched the NHC table during the repackage. I bagged it and store it in silo area. When we do drum clean up, I will throw it in the drum. |

David Wang | ITE | Standard Operation | | | ITE HV test woithout mdoule was done. |
Carla did the test. That is what she wrote in Feb 04th: "I am done with the HV testing at ITE - the results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE also has a band, from 54-56kV, where the current jumps around like crazy". |

David Wang | ITW | Standard Operation | | | ITW HV test without mdoule. |
Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at 59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb 02. |
