大电流、低发射度是惯性聚变能直线加速器重离子注入的基本要求。静电四极（ESQ）注入器能够提供这些高电荷密度和低发射度的光束。我们已经修改了现有的2 MV注入器，以减少束流发射度和增加一倍的脉冲长度。我们描述了改进的注入器提供的强流传输实验（HCX）的束流和有限的上升时间的提取电压脉冲在二极管上的束头的影响。我们演示了用于减轻像差和减少注入器中的束发射度增长的技术。
High current and low emittance are principal requirements for heavy-ion injection into a linac driver for inertial fusion energy. An electrostatic quadrupole (ESQ) injector is capable of providing these high charge density and low emittance beams. We have modified the existing 2-MV Injector to reduce beam emittance and to double the pulse length. We characterize the beam delivered by the modified injector to the High Current Transport Experiment (HCX) and the effects of finite rise time of the extraction voltage pulse in the diode on the beam head. We demonstrate techniques for mitigating aberrations and reducing beam emittance growth in the injector.
