[INSTRM-237] Implement automatic regeneration procedure for visible camera

Thu, 24 Feb 2022 20:38:10 +0000

After reaching the maximum allowed cryocooler power, it will be necessary to regenerate the cryostat.
To do so, we have designed a turbo-pump-based regeneration procedure.
The sequence is based on automatic or remote controlled operations including :

starting/stopping roughing, turbo and ion pumps
opening/closing the gatevalve.
stop/starting cryocooler

To speed up the process, the heater on the detector and spreader are used.

From a software pov, the main thread can be viewed as a sequence with:

Steps with associated actions;
Transitions with associated logic conditions

But there will be also other threads with asynchronous action in parallel.
