Abstract : An improved getter for a hydrogen maser comprised of screened particles of zirconium-aluminum alloy is described. One or more pump bodies are connected with a hydrogen maser and each pump body contains a quantity of Zr-Al alloy particles. One or more screens are provided in a passageway connecting a pump body with a maser to allow passage of hydrogen into the pump body but preventing, in a zero-g environment, the alloy particles from leaving the pump body. The Zr-Al alloy particles are activated by heating. (Author)
