Abstract
An inertial electrostatic confinement (IEC) fusion facility with inner ion source includes an anode, a cathode, a high-voltage lead-in support rod connected to the cathode, an inner ion source, a vacuum system, and a high-voltage system. An anode potential of the inner ion source is lower than an anode potential of the IEC; the cathode is a spherical net structure having longitude and latitude circles, and cooling channels are arranged in the longitude and latitude circles. An ion motion trajectory perturbation device (IMTPD) is arranged in the IEC for performing perturbation to change an angular momentum of an ion motion. IMTPD can avoid the ion loss for the long time confinement when the ion move back and forth in IEC. The high vacuum can avoid the ion loss and the power consume of high voltage source induced by the ionization. A neutron yield and a gain-loss ratio can be improved.
