HIGH-SPEED NONREFRIGERATED ISOLATION TRAPS FOR ULTRA HIGH-VACUUM SYSTEMS
A design is given for a nonrefrigerated isolation trap for use in ultra high-vacuum systems. The trap uses either artificial zeolite or activated alumina to retard migration of impurities and hold impurity molecules on contact. With zeolite the trap operated under ~3 x 10/sup -10/ mm Hg for 75 days; using alumina the trap remained effective for 100 days at < 1 x 10/sup -10/ mm Hg. (C.J.G.)
