Ultra High Vacuum System for Isabelle Full Cell

Conference ·
OSTI ID:5885691
A vacuum system consisting of a 40 m long 8.8 cm diameter stainless steel tube, pumped by 7 pumping stations, has been assembled using automatic welding methods. All components have been fired at 950°C in a vacuum furnace at a pressure < 1 x 10-4 Torr. Each pumping station contains a Ti-sublimator, a 30 liter/s ion pump and an UHV gauge. After assembly, the entire system was baked out at 250°C for 24 hours. A pressure < 1 x 10-11 Torr was reached after titanium flash. Surface treatment of stainless for 10-11 Torr operation, bake out and conditioning cycle to read 1 x 10-11 Torr, and leak checking at low pressures are discussed.
