Robust neutron source for resource exploration

为下一代紧凑型串联式DD或DT中子发生器研制了一种利用金属表面实现H-到H+的强效电子剥离器。实验结果表明，经过表面抛光后，反射粒子中的H+分数的转换效率提高，最高可达90%左右。用三维激光扫描显微镜测量了抛光和非抛光两种金属表面的粗糙度参数。表面测量表明，抛光后的平均粗糙度提高了4倍。

A robust electron stripper for H- to H+ using a metal surface was developed for a compact tandem-type DD or DT neutron generator of next generation. The experimental results showed that the conversion efficiency, H+ fraction in the reflected particles, improved by surface polish up to the maximum value of about 90%. Roughness parameters were measured for 2 samples of metal surface, polished and non-polished, using a 3D laser-scanning microscope. The surface measurement indicated that there was factor 4 improvement in the average roughness by polish.
