With this process pump we reach fore-vacuum pressure of 3.0 Pa with a gas throughput of 0.24 hPa m 3 s-1. With a maximum turbopump fore- vacuum pressure of 3.3 hPa, this configuration is conservative despite the thermally demanding process gas argon. The process gas is admitted to the chamber (1) via a mass flow controller (5).
