 A vacuum controll instruments are implemented in the cryostat. As a pump functions the HighCube 80eco, as a sensor a PKR 251 connected to a TPG361 is used, all from PFEIFFER Vacuum. A solenoid valve is implemented in the system to separate the cryostat from the pump. A vacuum controll instruments are implemented in the cryostat. As a pump functions the HighCube 80eco, as a sensor a PKR 251 connected to a TPG361 is used, all from PFEIFFER Vacuum. A solenoid valve is implemented in the system to separate the cryostat from the pump.
 As a solenoid valve funtions the **0211** from Bürkert,  it is a normally closed device, meaning applying energy will open the device. If it's Powered on it connects the pump to the chamber. Furthermore, the vacuum pump and the solenoid valve are both controlled via the PDU, while the single gauge is controlled via a LabVIEW Script via the server. As a solenoid valve funtions the **0211** from Bürkert,  it is a normally closed device, meaning applying energy will open the device.

 +===== Depressurization Checklist =====
 +
 +  - Ensure that cryocooler is off and cryostat is at room temps!
 +  - Turn on main power switch on HiCube Eco 80
 +  - Wait for DCU to complete self-test of system
 +  - Check if venting is off under parameter 012 “Enable vent” => off
 +  - Turn on roughing pump: Select parameter 010 “Pumping station” => on 
 +  - Once we reach pressures !!< 5 mbar!!, select parameter 023 “ motor pump” and turn on turbomolecular pump
 +  - Ideally, we want pressure to drop to lower 10^(-6) mbar range 
 +
 +
 +
 +
 +===== Pressurization Checklist =====
 +
 +  - Turn cryocooler off and wait for temperatures to reach ~ 280 K
 +  - Turn off Turbomolecular pump and wait for RPMs to go to zero
 +  - Turn off roughing pump
 +  - Vent the system
