Turbopump Vacuum Package Assembly (shown on s100)
Turbopump Vacuum Control Unit (VC1130 rear panel)
2.1.1 Intended Use
The turbopump vacuum package is an assembly of vacuum hoses, valves, gauges, and components
designed for integrating a turbopump with the Montana Instruments Cryostation platforms. The
configuration should only be used with compatible Cryostation systems containing the appropriate
hardware, software, and electronics.
2.1.2 Components
The turbopump vacuum package consists of a VC1130 model vacuum control unit with integrated
Pfeiffer Vacuum® HiPace® 80 turbopump, a full-range Pirani/cold-cathode UHV vacuum gauge, a KF40
electromagnetic vacuum valve, a 4 ft KF50 vacuum hose, a 10 ft chamber vent hose, and several KF
clamps, O-rings, and adapter fittings.
Configuration
The UHV gauge is mounted on a manifold inside the main body of the cryostat tower behind the
cryocooler. The vacuum valve assembly then connects to the vacuum port on the back panel of the
cryostat with a KF25 cross adapter between the two connection points. A KF50 vacuum hose runs from
the other end of the valve to the nearby vacuum control unit with integrated turbopump. A 4 ft KF50
hose is provided standard, and up to one additional 4 ft extensions can be added if the vacuum control
unit needs to be placed further away from the cryostat.

Option User Manual
12
Rear Manifold Pumping Configuration
In the rear manifold pumping configuration, the sample chamber is pumped out through the crosslink
assembly that connects the sample chamber to the cryostat cooling tower. One side of the KF25 cross is
capped off.
» NOTE
Due to the location of the UHV gauge, vacuum pressure readings may be up to an order of
magnitude lower than actual sample chamber pressure when used in the rear manifold pumping
configuration.
Rear Manifold + Side Panel Pumping Configuration
Extra components for the alternative parallel side panel pumping configuration are provided. In this
assembly, a 20-in KF25 hose is connected to the KF25 cross inlet between the valve and vacuum port on
the back panel of the cryostat. The hose is then routed around the side of the cryostat to a KF25 side
panel on the sample chamber.
» NOTE
The rear manifold + side panel pumping configuration will provide greater conductance for pulling
vacuum in the sample chamber. For best turbopump vacuum performance, and for the most
accurate sample chamber pressure readings, it is recommended to use this configuration
whenever side panel access is available.
