Obtention of pressures in the 10-14 torr range by means of a Zr-V-Fe non evaporable getter

  • 1. European Organization for Nuclear Research, Geneva (Switzerland)

Description

Pressures in the low 10-14 torr range have been reproducibly achieved in a 3 m long vacuum chamber. Pumping was provided by a 400 l s-1 sputter-ion pump, a titanium sublimation pump and 43.5 m of a Zr-V-Fe Non Evaporable Getter (NEG) strip. Activation of NEG has been passively achieved during the initial bakeout of the vacuum system. The pressure has been measured by means of a modified version of the Helmer gauge, designed and manufactured at CERN. (author)
