Xx. Wang et al., PURE ELECTRON-PLASMA EXPERIMENT, Science in China. Series A, Mathematics, Physics, Astronomy & Technological Sciences, 36(11), 1993, pp. 1340-1346
A pure electron plasma apparatus is described. Its basic parameters ha
ve been measured and compared with those of theoretical equations. A s
ignal with high frequency has been observed in an injection phase, whi
ch may possibly result from ''virtual cathode'' oscillation.
