Development and fabrication of electro-magnetic shock tube with high resolution spectrometer for stopping power measurement in atomic hydrogen gas

Abstract

Stopping power measurement in matter is very important for heavy-ion fusion and heavyion- driven high-energy density physics [1]. The database of the stopping power has been developed for many elements and compounds under a normal temperature and pressure [2, 3]. However, the stopping cross section can change due to a change of electronic state in the target such as excitation and ionization [4, 5]. Especially, there is few experimental results for the energy loss of charged particles in a dissociated target. Hydrogen is a suitable element to investigate the dissociation effect because it has only one valence electron...
