摘要：

An Inertial Electrostatic Confinement (IEC) fusion device is studied for a compact fusion neutron/proton source using a magnetron discharge as an external ion source. The addition of ion sources to the IEC device is to enhance the efficiency of fusion reactions by lowering the operating gas pressure and by providing beam-like ion energy distribution. At lower gas pressures, charge exchange collisions are reduced, resulting in longer ion lifetime and enhanced ion re-circulation. An improvement in normalized neutron yield about a factor of ten has been observed with respect to grid current and the operating gas pressure at greatly reduced operation gas pressure of 0.1 Pa.
