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

摘要

Stopping power measurement in matter isvery important for heavy-ion fusion and heavyion-driven high-energy density physics [1]. Thedatabase of the stopping power has been developedfor many elements and compounds undera normal temperature and pressure [2, 3]. However,the stopping cross section can change dueto a change of electronic state in the target suchas excitation and ionization [4, 5]. Especially,there is few experimental results for the energyloss of charged particles in a dissociated target.Hydrogen is a suitable element to investigatethe dissociation effect because it has only onevalence electron...
