Page 20: Vacuum Control Unit
Front of Enclosure 2.3.1 Intended Use The vacuum control unit is used for vacuum control of Montana Instruments Cryostations. It is designed to connect to the system control unit and Cryostation provided by Montana Instruments. It is recommended to locate the vacuum control unit near both connected apparatuses. - Page 21 Cryostation The roughing pump is used to achieve a low vacuum. A high vacuum is achieved with cryopumping. During cooldown, the sample platform temperature lags the Stage 1 temperature in the Cryostation by ~100 K this allows for remaining molecules to be trapped by the charcoal adsorbers and cold surfaces conductively connected to Stage 1 rather than the sample.
