|
Tried to leak check TM4 Ta57# at TCS. LD failed to pump down properly at fine range. It always tripped at 4 torr. I cheeked all vacuum lines seals and
adapters on top of module to LD. Everything is good. Chad said the VCRs at SHC can not be tightened any more. Discussed with Anders, we decide to move
module TCS and helium pressure test there. The same difficult happened last time on TM4 UCx24# at SHC when leak check. But,it is solved by pressurize |

|
I did a HV test on TM3 at TCS yesterday. HV Ramp up speed: 1KV per 5 minutes when below 30KV,1KV per 10 minutes from 30-36KV. There is no major spark
below36 KV . I could see lots small and big vacuum response on IG1 and PNG2 when conditioning from 30-36 KV, especially when closing to 36
KV. However, At 36.4 KV, There is a big continuous spark occurred. It could not be stopped until I lowed the HV to 14KV. I have to ramp up from 14 |

|
The south hot cell window has been found to be leaking oil. Upon inspection yesterday I found that the bolts compressing the gasket on the cold side
were "loose". I have re-torqued them to the specification provided by the manufacturer in the attached procedure. |

|
On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during
installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener
was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further. |

|
UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that
the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached
photo. More photos are available on DocuShare |
