|
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 |

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 |

|
ITH MP1 is replaced today with a new style pump.The new pump is 0.75 inch higher than old pump on inlet and exhaust so a new solid inlet adapter
(KF50-25) has to been used. For future secondary pump ITH MP1S replacement, we need a new adapter 0.75 inches shorter as well. The new pumps
is started . Everything works fine. Old pumps is drained , bagged, and stored in TH B2 level. All radioactive garbage produced during the job are bagged |
