|
Starting at 11:00 am and finishing at 12:10 Ucx#4 previous target was removed and UCx#4 installed and leak checked on TM1.
During module move to the hot cell UCx#4 was housed in a bag under argon. |

|
Chad and i did a leak check on TM1heat shield with UCx target on.The circuit are pumped down to the bottom leak rate and base pressure is 3xE-3
torr on the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them ( tested individually,2 seconds
every time ) . The test repeated 1 time.There is no response on leak detector during 45 seconds waiting time on both time.Chad flushed helium around the |

Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG4 3.6 xE-6 Torr, IG1 1.1xE-6torr, IG4(diagnostic box) 3.4xE-6
Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 4 mins . There
is no response on leak detector. The heat shield circuit is leak tight. |

|
I removed 5 shielding blocks from ITW to block storage area, and disconnected TM1 in ITW. After UCx run, the radioactive level around the turbo
pumps and primary vacuum lines are pretty high. This affect the general field inside the ITW pit around working area.i took 15 minuts to finish the job
and i got 0.1msvr dose. the general field around my working area is about 350 usv/h. |

|
Chad and i did a leak check on TM1 heat shield circuit with new Nb#7 target installed. It took about 5 mins pump down the circuit to leak rate 0.0x
E-9atm.cc/sec and 0.0x E-4 torr on leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight. Chad sprayed helium on |

|
TM#1 with Nb#7 attached was electrically checked at the south hot cell yesterday, see attached pdf for details. Some notes about this test the oven to
the 60kV common is 2Mohm this was noticed on the target prior to installation on the module, and the 60kV common to chassis is low at 874Mohm (low as in
a non infinite value). |

Leak detector pumped down to base LR1.3xE-9 atm.cc/sec, and BP 8xE-3 torr. All high vacuum gauge readings at CS and TM1 are at low -6 range from 1.2xE-6torr
to 4.6x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit
is leak tight. |
