| Research Abstract |
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.
