Injection of a relativistic electron beam into neutral hydrogen gas

Abstract

The injection of a relativistic electron beam (0.8 MeV, 6 kA, 150 nsec) into hydrogen gas of 190 Pa pressure results in a plasma with density ne≃1020 m−3 and temperature kTe≲kTi≃3.5 eV. The results of the measurements show good agreement with computations based on a model combining gas ionization and turbulent plasma heating. It is found that a quasistationary state exists in which the energy lost by the beam (about 6% of the total kinetic energy of the beam) is partly used to further ionize and dissociate the gas and for the other part is lost as line radiation.

“…It is not surprising to find up till now a long list of studies and research on beam-plasma interaction and applications, which was also reviewed by many authors, e.g. [1][2][3][4][5][6][7].…”
