|
Vacuumed out remainder of debris from the wall penetration, removed cradle and checked condition. Down stream support bracket sees advanced stages of
material loss (OBO 20-30% loss). See attached photos.
RPG reports that the removed beam tube has 15k CPM on the interior of the beam tube. |

|
Yesterday we installed the 2a2 window, the drive screw was torqued until 70
ft-lbs and we stopped, the yoke is not fully closed to its hard stop with roughly 7/8" to 3/4" still to go. Similar to identical conditions to
2a3 beamline window install, see https://elog.triumf.ca/TIS/RH-ISAC/647 for that install. Otherwise |

|
Anders and I leak checked new 2A2 window seal on ITW side. Leak detector was connected to ITW TP4. Base leak rate 0.0Xe-9 atm.cc/sec.
base pressure 0.0xe-4 torr. Sprayed 15-20 psi directly underneath 2A2 window by using exist 2a2 window leak check copper tube. The leak detector
got response in 5 seconds when helium was applied. the leak rate was 5xe-6 atm.cc/sec. Once the helium source was closed, the leak rate dropped quickly |

Leak detector is connected to ITW TP4. LD Base leak rate 0.0XE-09 atm.cc/sec. Helium line is connected to existing window leak check 1/8 " copper
tube. Applied 18psi helium for 1 minute. No response on LD. The window seal is good on ITW vacuum vessel. |

A Motorla CP200 portable two-way radio was tested today for use inside the ISAC hot cells. A High Technology Communications Throat microphone
PRO model from Planet Headset was used with the radio. Chad entered the NHC wearing the throat mic and radio under a air supplied hood to mimic real
world conditions. Communication was clear with the other person in the NHC service area, in the SHC service area, at various locations on the B1 |

Installation of the diagnostic connections between the NHC hot and cold sides has been completed. The cable bundle was prepared by Travis Cave
in the electronics workshop with connectors attached at one end only. Metal fish tape was first ran through the conduit from the cold side to hot
side, the non-terminated end of the cable bundle was attached to the fish tape inside the cell, cable pulling lubricant was applied, then the cable bundle |

|
I did a helium pressure test on TM2 HS line at TCS. At 70psi helium, the leak rate is 2.5 xE-7 atm.cc/sec. I think this is the number that close to result
before which is 1.7xE-9 atm.cc/sec. WE know there is a small leak on this water block seal. Chad and I did helium spray check yesterday at
SHC. It was good at bottom scale. No much worry on this low E-7 range leak. |
