AdV- VAC CTRL SYS/Cryo Interface 06Feb2013

Cryotrap cryogenics (simplified sketch) = the ‘electronic’ equipment needed to read LN2 level, temperature, controller of feeding valve, phase separator electronics...

‘Control System’ The general system that collect data from all vacuum equipment and operate them also by remote trough the supervisor SW. A ‘Vac Rack’ is foreseen for each crytrap, it will allow the operation of vacuum pumps and valves, and interface also with cryogenic equipment (And also interface with DAQ)

Some tasks related to cryo equipment Need to operate cryogenic devices (adjust the set point of LN2 level, feeding valves closing, start / stop temp sensors...) from Local. And also by remote (a few of them..., normally by the general vacuum SW) Need to provide some interlocks from the ‘cryo equipments (alarms) to the ‘rest’ of the system Need also to monitor ‘most’ signals from cryo equipment and record them (normally by the general vacuum SW)

Example of interlocks Alarm of cryotrap over temperature Set point temperature reached (<80K) Alarm of high LN2 level Alarm of low LN2 level Set point LN2 reached Phase separator alarm...

Signals monitored by remote Most of available ones, example

‘’Interface definition & task sharing’’ Discussion about the task sharing and to prepare the exchange of information
