MuSR: 3He Refrigerator Document VI Cryogenic Control Logic

JamesKingWork commented 3 years ago

As a MuSR scientist, I would like the cryogenic control logic for the 3He Refrigerator to be correct and approved with cryogenics.

Acceptance criteria:

[x] VI Cryogenic Control logic is documented (on the dev manual)
[x] The logic is approved by the cryogenics team (or is edited to match what they expect)
[x] An estimate of time to implement the logic is given

Notes:

The 3He refrigerator is a Heliox/ITC503 based system
LabVIEW VIs are at C:\LabVIEW Modules\Oxford Software\Muon Heliox

Confirmed with cryogenics and MuSR scientists that this is purely ITC503 and doesn't use ITC502s and ITC601s as the LabVIEW suggests

Impeded waiting meeting for discussion with cryogenics on Friday. Documentation to discuss is attached here.

After talking to cryogenics on Friday there were a number of notable differences between my expectations from the VI and the realities of the device. I have updated the document and sent it to cryogenics to get feedback.

See docs. After a talk today with cryogenics they have approved the logic.

The docs make enough sense to me, and the progression of documents is visible in this ticket.
