Research Abstract

We have developed solid hydrogen targets for nuclear experiments, using newly developed method. First, we have developed large-size solid hydrogen targets, D=50mm, L=30mm/100mm in thin films. These targets were used for two nuclear experiments at RIKEN. Second, we have developed a thin windowless solid hydrogen target by hydrogen gas blowing in vacuum on pure silver foil with 30μm thickness. The target size was 0.35mm in thickness and 5mm in diameter. This solid hydrogen target will be used for nuclear experiments at TRIUMF (Vancouver, Canada) from 2011.
