Standard Laboratory Vacuum System Stations
Turbo-Pump Based Stations
- The Turbo-Pump Based Vacuum Station is a system used to produce high vacuum ( 10-6 < X < 10-9 Torr ) in beamlines and experimental chambers through out the lab. Turbo pump, or more exactingly turbomolecular pump, systems are throughput pumping systems, which means that the gases that are removed from the evacuated space are continuously discharged into the atmosphere. Turbo pumps cannot discharge to atmospheric pressure and require a roughing pump to interface between the turbo's discharge port and atmosphere. In our lab, this roughing pump is typically an oil-sealed, rotary-vane vacuum pump but may sometimes be an oil-free, dry scroll pump.
- The standard turbo pump station consists of the following components:
- A single turbomolecular vacuum pump
- A single roughing pump
- An electro-pneumatically operated, high throughput gate valve
- A hand operated (usually) or an electro-pneumatic (rarely) foreline valve
- A molecular sieve foreline trap
- Various interconnecting vacuum hose and fittings
- A foreline vacuum gauge
- Dual chamber/beamline vacuum gauges
- A vacuum pump gate valve interlock circuit
- A panel mounted indicator & control panel
