Construction of Simple Non-Evaporable Getter Assemblies Using St707 Strips

Abstract

Two types of simple non-evaporable getter (NEG) assemblies have been constructed using commercial St707 strips. The first one can be activated by direct current heating at 15 A. The second can be activated by indirect heating using a tantalum heater at 12 A. The base pressure of the chambers pumped solely by the first and the second NEG assemblies reached 2.4×10−8 and <1×10−8 Pa, respectively.
