Development Strategy of RF Ion Source for Neutral Beam Injector in Fusion Devices

Large-area RF-driven ion source is being developed at Germany for the heating and current drive of ITER device [1, 2]. Negative hydrogen ion sources are major components of neutral beam injection systems in future large-scale fusion experiments such as ITER and DEMO. RF sources for the production of positive hydrogen ions have been successfully developed at IPP (Max-Planck-Institute for Plasma ...

Grant Logan Lawrence Berkeley National Laboratory University of California, Berkeley, California, 94720, USA Highly ionized plasmas are being considered as a medium for charge neutralizing heavy ion beams in order...

Rf Plasma-based Ion Source Modeling on Unstructured Meshes

Ion source performance for accelerators and industrial applications can be improved through detailed numerical modeling and simulation. There are a number of technical complexities with developing robust models, including a natural separation of important time scales (rf, electron and ion motion), inclusion of plasma chemistry, and surface effects such as secondary electron emission and sputter...

Development of Superconducting Quadrupoles for Heavy Ion Fusion

Multi-beam heavy-ion accelerators are considered as promising drivers for inertial fusion energy. The High Current Experiment (HCX) at Lawrence Berkeley National Laboratory (LBNL) will test driver-scale beam dynamics in a single transport channel. Single bore, NbTi superconducting quadrupoles are being developed for the HCX, taking into account their possible use as modules in a quadrupole arra...
