Plasma heating by injection op relativistic electron beams in neutral gas


We report laser scattering measurements of the electron density of a magnetized plasma produced by a relativistic electron beam (350kV, 50kA, 100ns, 2 cm diameter) injected into neutral hydrogen. Electron number densities of ~5 10<sup>15</sup> cm<sup>-3</sup> corresponding to ≳ 20% ionization and electron temperatures <; 10eV are observed during the late… (More)
