|
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray.
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there. The result is close to before. |

|
TM2 HS line helium leak check is done. leak detector base LR 1.8xE-8atm.cc/sec. helium pressure 70 psi. 5 minutes test. no change on LD leak rate.
I spray lots helium to gas line adaptor and fittings. No leak.has been found at this base leak rate level. Since the TCS MP1 has some
issue ,this time the base leak rate on LD only can get to 1.8Xe-8 atm.cc/sec at this moment instead of 0.0xE-9. The low E-8 level is not perfect, |

|
First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak
on R/U coil circuit.
Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed |

|
Firday, November 8 all water blocks (excluding I and K) were blanked off and vacuum leak checked. No responses were found. (First Picture)
I and K could not be blanked off without removal of the water block jig. Also, I dropped one of the blank offs onto the table, so one line could
not be blanked off until a new clean blank off was inserted into the cell. In addition, there was still reminace of a bolt in block Ias it aslo could not |
