Figure 4
Transmission of the differential pumping recorded in the 250–50 nm range in one atmosphere (1013 hPa) of air, nitrogen, argon and neon with the differential pumping in operation for 400 mA ring current and top-up machine mode and 2000 µm slits. A gate valve bearing a MgF₂ window separates the beamline from the differential pumping.
