Negative Hydrogen Ion Sources for Fusion: From Plasma Generation to Beam Properties
Frontiers in Physics, 2021 The neutral beam injection systems for the international fusion experiment ITER used for heating, current drive, and diagnostic purposes are based on RF-driven negative hydrogen ion sources with a source area of roughly 0.9 m × 1.9 m. The sources operate

Single ions trapped in a one-dimensional optical lattice
, 2012 We report on three-dimensional optical trapping of single ions in an optical lattice formed by two counter-propagating laser beams. We characterize the trapping parameters of the standing wave using the ion as a sensor stored in a hybrid trap consisting ...

Optimization of an RF driven H/sup -/ ion source [PDF]
Conference Record of the 1991 IEEE Particle Accelerator Conference, 2002 A radio-frequency (RF)-driven multicusp source has recently been developed to generate volume-produced H/sup -/ ion beams with extracted current density higher than 200 mA/cm/sup 2/. The output power of the RF generator and the insulation coating of the antenna coil have been improved. The antenna position and geometry and the filter magnetic field for

Alternative RF coupling configurations for H− ion sources [PDF]
AIP Conference Proceedings, 2015 RF heated sources for negative hydrogen ions both for fusion and accelerators require very high RF powers in order to achieve the required H− current what poses high demands on the RF generators and the RF circuit. Therefore it is highly desirable to improve the RF efficiency of the sources.
