Interlock
Cooling unit interlock:
conditions and action:module too cold: T (module) < -45 C and T(coldplate) > -45 C : turn off peltier and turn off
modulemodule + chiller
module too hot: T (module)> 35 C : turn off module and peltier (?) + chiller
condensation:
T (module) < dew points: turn off peltier and turn off module + chiller
flow of dry air < 1.5 L/min (? number need to be tested): check dry air connection
vacuum status: alarm
pressure gauge (threshold) : check vacuum status or piping
T(module)-T(vacuum chuck)>threshold (need to test if the module and vacuum chuck not connect well what is the number) : check vacuum status or piping
peltier properly setup:
T(vacuum chuck) > T(chiller): turn off module and peltier
chiller status: alarm
(need to consider about leakage of coolant or some problem related to chiller) T (coldplate) -T(chiller set) > threshold (need to check) => need to shut down pelter + module + chiller
Chiller
There are two ThermoCube units in B84/TID cabinet. Unit #1 is with full tubing setup and regularly used by Gabriel Blaj for LCLS so that we are trying to use unit #2 (no tubing) by assembling similar tubing arrangement as unit #1. Unit #2 has different coolant connectors compared to unit #1, but the rest of the tubing can work the same way still.
