In this paper, an electrostatic plugging and butt-type plasma confinement system and experimental method are described. The experimental results of electron injection, plugged electrode and plasma confinement performance are given. The results are analyzed and discussed as necessary. The plasma parameters obtained are: density n = 2 × 10 ~ (10) cm -3; life τ = 2ms; electron temperature T_o = 50eV; plasma potential φ_p = -68V. Proved the relationship between density and magnetic field calibration, the role of plugging the electrode is obvious and effective, the main experimental results and the theory. The device will carry out plasma accumulation and heating, potential shielding, electrostatic plugging axial symmetry cascade mirror end-plug research.
