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