Abstract (en)

[origin: WO9924990A2] A pulsed neutron/proton source based upon the design of a steady-state spherical inertial electrostatic confinement (IEC) configuration and using a pulsed gate valve grid (GVP). The IEC-GVP device comprises a grounded conductive vessel, serving as an anode, and a central cathode or primary grid that is connected to a high voltage source. In addition, an intermediate second grid and an outside third grid are disposed concentrically with the central cathode within the vessel. Electron extractor/emitter devices are disposed substantially symmetrically about the perimeter of the vessel and include electron extractor deflector grids and electron emitters that contribute to the enhanced timed ion flow in the device. Two techniques for pulsing the second grid are used. A first is a low repetition rate GVP (LR-GVP) operation and a second is a tuned high-frequency pulsing, termed Resonant Ion Driven Oscillation (RIDO) GVP operation.
