ABSTRACT:
A getter sorption pump has at least one getter member of non-evaporating getter material and a corresponding heating element. The specific performance of the getter pump is increased along with a simultaneous reduction of necessary heating capacity, and it is stabilized over a long time period by use of a heat accumulator having an extremely high heat storing capability. For this purpose, the heating element is attached to a sintered ceramic body, and an insulating tube onto which the getter member is sintered, in situated thereabove. The getter pump is employed in high-vacuum and gas discharge systems.
