本文从实验上研究了用钕-钇-铝-石榴石激光器“直接注入方案”的可行性。测量了电荷分布与激光功率密度的关系。在峰值电流脉冲强度为1.6×1011W/cm2时，C6+的产率为46.8%。测量了在该强度下到目标的距离的电流依赖关系。当φ引出孔径为4.8 mm时，C6+的峰值电流为60 mA。由程序PTEQ-HI模拟的入射束流条件发现，TIT-RFQ可以加速大电流(从12 mA到28.6 mA)。
The feasibility of a “direct injection scheme” using Nd–yttritium–aluminum–garnet laser has been studied experimentally. The relationship between charge distribution and laser power density was measured. The obtained yield rate of C6+ was 46.8% at the peak current pulse with 1.6×1011 W/cm2 laser intensity. The current dependence of the distance from the target at this intensity was measured. The peak current of C6+ will be 60 mA with φ4.8 mm extraction aperture. It was found from the input beam condition simulation by the code PTEQ–HI that high current (from 12 to 28.6 mA) can be accelerated by the TIT–RFQ.
