Agenda and Minutes¶
Action: Ed, Spare Boards still need temp on RH boards and bias calib on LH boards.
Status of hardware upgrades, spares and essential works: EO CMW
- cold heads and boards
- compressor services and spares
- waveguide swaps
- helium leak-tighting
Cryo 1 and 2 are now warm and are are being serviced on April 5th. The waveguide swap will happen on the same day if possible.
We have all four absorbers and plan to swap them soon.
Craig has found the problem with the speed at which we burnt through compressors. There was a short on the interlocks for the cryostat which meant that the compressor was permanently on. We can now fix this but it is a bit of a design flaw.
Helical Efficiency Improvements: AD and Round table discussion,
Adam has some tried including some less than perfect tracks but sees very little improvement in the efficiency. He has some misgivings about a least squares fit as it will be to a tan function and hence will have multiple solutions He will discuss with Ken.¶
Descoped cooling Tracker design¶
We have discussed having a meeting to discuss the UK works. Melissa will email all.
