Abstract: An ion getter pump for providing a vacuum in a high power microwave discharge tube consists of a body of radio-active material which is arranged to act as the power source for the pump. The pump has a glass support base concentrically surrounding a cathode. Mounted within the tubular cathode is a layer of radio-active isotope material and a particle receiver from which extends an anode rod. Pins are fused through the base to support the cathode, the particle receiver and the isotope material. A shield is provided to prevent sputtering of material on to the base.
