The ISABELLE full cell vacuum system, consisting of a 40 m long by 8.8 cm diam stainless steel tube pumped by seven pumping stations, was assembled and processed for 10/sup -12/ Torr operation. Evaluation and testing of the system and its subassemblies has been completed. Detail design of system components and the determination of the conditioning process was completed. The best procedure to rough pump, leak test, vacuum bake the system, condition pumps, degas gauges, turn on ion pumps, and flash sublimation pumps was established. Pressures below 2 x 10/sup -11/ Torr are now routinely achieved in normal operation of the full cell. This includes pump down after replacement of various components and pump down after back fill with moist unfiltered air. The techniques developed for the full cell will be used to build the ISABELLE ultrahigh vacuum system.
