  • Lab Update - Run 82 preparation
    • Fridge Status :
    • LN2 transfer and LHe transfer completed. We are at 4K!
    • After multiple checks, we discovered leak in the copper pipe which goes to the recovery system.
    • Since we can't replace it, we added a regulator valve to that side of the Tee.
    • After LN2 blowout, the copper pipe break out of the connection by its own, possible mechanical tension around that area.
    • Mike helped to fix that pipe and we plug that back in. We can hear a hiss in the other end of the pipe while doing LHe transfer, we are not leak tight there.
    • LHe liquid level meter was erroring out during LHe transfer. But after multiple power cycle, it seems to work back on.
    • Plan is to start the 1K pot today. The 2nd LHe transfer can be tomorrow, so we donot have to have more people on Thursday. MB is at 85%.
