RF Ion Gun Injector in Support of Fusion Ship II Research and Development

Abstract

Abstract. Ion injection into the Inertial Electrostatic Confinement (IEC) fusion power plant used in the design of the high performance Fusion Ship II (Burton et al., 2003) is a key technological issue for development of this concept. This paper discusses the design and initial experiments with a radiofrequency (RF) ion gun designed for this purpose. The RF Gun design described here was found to have some important advantages over other ion gun designs: simple construction, a higher extraction efficiency; 10 ((mA/cm 2 )/W), a lower divergence; 10.8 ± 0.36 mrad, and a very intensive ion flux; 6 x 10 18 ions/(cm 2 .sec) measured at 0.27 Pa.

Theoretical and experimental studies of a planar inductive coupled rf plasma source as the driver in simulator facility (ISTAPHM) of interactions of waves with the edge plasma on tokamaks

“…Then particle fluxes and their velocities are needed. Another important issue about these parameter applications is in fusion instruments such as thing that ISTAPHM and IECF [19].…”

Prediction of Neutron Yield of IR-IECF Facility in High Voltages Using Artificial Neural Network

“…Reported results in previous works suggest that using the D-T gas mixture and increasing the ion current via ion source would give a neutron rate of 7.3 × 10 12 n/sec at 1.2 mTorr, 75 kV, and 1.5 A ion current [6,8,9]. Researchers in Wisconsin University, in order to increase and optimize the neutron production rate in the UW IECF device, studied effect of cathode's size (diameter), geometry, and material composition on NPR [10].…”
