| + !Automatic Cryostat Control and Monitoring |
| + |
| + All our cryostats are monitored and controlled with [SEA|http://lns00.psi.ch/sinqwiki/Wiki.jsp?page=Sea].\\ |
| + All instruments are equipped with a temperature controller (Lakeshore 340) for the temperature control \\ |
| + and a cryostat control unit (CCU) for the control of pressures, levels and valves.\\ |
| + The CCU will only work with a correctly configured SEA instance. It can read the pressure in the VTI pumping line\\ |
| + (see [orange cool down|http://lns00.psi.ch/sinqwiki/Wiki.jsp?page=OrangeCryostatCooldownProcedure] and set the needle valve accordingly.\\ |
| + It reads the analog output of AMI Helium level meters and serves as a level indicator for our 2 point liquid Nitrogen level meter.\\ |
| + The Unit is used to energize the electromagnetic valves involved in the automatic Nitrogen/Helium refill. |
