Subject: ITW beam tube repair job 

2A2 window has been removed from ITW and beamlines has removed the beamtube from the penetration. The penetration has been sealed with plastic sheeting and duct tape to maintain the ventilation depression between the 2A tunnel and the Target Pit.

Window is currently stored in a lead flask in the target hall. Window fields are 26 mSv/h OC, 1.2 mSv/h at .5m. There is a 10 uSv/h field outside the flask with the window inside it.

Clamp is currently sitting bagged in ITW Station Pit, it is quite corroded.

Tank flange was video inspected but still needs to be cleaned, currently there is a slip on dust cover over the flange to protect it.

Work will resume after the nuclear ventilation comissioning is completed.
