Abstract The Compact Ignition Tokamak (CIT) will use an advanced, high-velocity pellet-injection system to achieve and maintain ignited plasmas. Two pellet injectors are provided: a highly reliable moderate-velocity (1- to 1.5-km/s), single-stage pneumatic injector, and a high-velocity (4- to 5-km/s), two-stage pellet injector that uses frozen hydrogenic pellets encased in sabots. Both pellet injectors are qualified for operation with tritium feed gas. Issues such as performance, neutron activation of injector components, maintenance, design of the pellet-injection vacuum line, gas loads to the reprocessing system, and equipment layout are discussed. Results and plans for supporting research and development (R&D) in the areas of tritium-pellet fabrication and high-velocity, repetitive two-stage pneumatic injectors are presented.<<ETX>>
