Investigation was conducted to determine optimum discharge chamber configuration of 15-cm-diam, mercury-bombardment thruster for SERT (Space Electric Rocket Test) II mission; thruster used thermionic, oxide magazine cathode and permanent magnets; systematic variation of magnetic field shape and strength, propellant introduction mode, and ion extraction system determined final configuration which provided thruster operation at 0.25 amp beam current and 3000 v net accelerating potential at propellant utilization efficiencies in excess of 90% for some operating conditions; other findings.
