Summary

The application of non-evaporable zirconium-vanadium-iron getters to enhance and maintain the vacuum of cryogenic systems have been studied. It has been shown that the pressure rise rate of the insulation space of these systems is significantly reduced by the getter activation. The gettering action is substantial even at ambient temperature for many gases including hydrogen which can not be cryosorbed at liquid nitrogen temperatures. The getter can be activated several times and it can act as in-situ pumps for cryogenic systems, especially for field units.
