chad fisher | South Hot-Cell | Standard Operation | TM4 | UCx#5 | NiO#1 removal UCx#5 installation |
NiO#1 was removed this morning.
UCx#5 was inserted into the hot cell around 1 pm, installed and leak checked and ready to go to the conditioning station 1:40pm
did have a little trouble with the 9 pin connector. It had to be lossened to get it to mate properly. It was le-tightened once the proper fit was achieved. |

David Wang | Conditioning Station | Repair | | | Replace conditioning station scroll pump in target hall |
Grant and I replaced the conditioning station broken srcoll pump with a refurbished scroll pump which is supplied by vacuum group. The replaced pump is bagged and waiting for RPG further survey in target hall . The target hall is survey after the job, and everything is fine. |

David Wang | ITW | Standard Operation | TM1 | Nb#7 | TM1connected in ITW |
TM 1 is in ITW now. All connections are done. The turbo pumps had been started this afternoon. The vacuum looks good so far. The water interlock check which related to TM1 are done. They are good. All TM1 water signals are visually checked and they are strong. The rest interlock check ( MCR XT page) will be finished before shielding blocks moving. The MAA is locked and ITE is ready for proton beam. |

David Wang | Conditioning Station | Standard Operation | TM1 | Nb#7 | TM1 Nb#7 target heat shield helium pressure check is done. |
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. |

Travis Cave | South Hot-Cell | Standard Operation | TM1 | Nb#7 | Electrical check |
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). |

David Wang | South Hot-Cell | Standard Operation | TM1 | Nb#7 | leak check heat shield circuit |
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 each VCR joints for 2 seconds every time. During 45sec waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 45minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM1 is in CS and under vacuum.

Travis Cave | Spent Target Vault | Standard Operation | | UCx#4 | Spent target move |
UCx#4 has been moved from the south hot cell to the spent target vault. The target was placed in pail #99 and now resides in spot 3C of the vault. It measured 55.3mSv/hr at ~1m from the hot cell. See attached PDF for further spent target vault details. |

David Wang | ITW | Standard Operation | TM1 | UCx | TM1 disconnected in ITW |
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. |

David Wang | ITE | Standard Operation | TM4 | NiO #1 | ITM4 in ITE connected and pumping down |
TM4 had been connected in ITE. Six turbo pump had been started . thepumpming diwn is very good so far. The water interlock check on ITE and TM4 had been finished and everything is good.All water signals are strong and constant by visually checking. |
