Inertial electrostatic confinement fusion device with gate-valve pulsing

摘要

The pulsed neutron / proton source is based on a steady state spherical inertial interruption (IEC) arrangement and utilizes a pulsed gate valve grid (GVP). The IEC-GVP device comprises a grounded conductive container 12 acting as an anode and a central cathode or first grid 13 connected to a high voltage source. In addition, an intermediate second grid 14 and an outer third grid 15 are arranged concentrically with the central cathode 13 in the vessel 12. The electron extractor / emitter device 16 is disposed substantially symmetrically with respect to the perimeter of the container 12 and includes an electron extractor deflector grid 17 and an electron emitter 18. Two techniques are used to pulse the second grid. The first technique is low repetition rate GVP (LR-GVP) operation, and the second technique is coordinated high frequency pulsing called resonant ion driven oscillator (RIDO) GVP operation.
