The periplasmatron, An ion source for intense neutral beams

Nuclear Instruments and Methods, 1976
Abstract An intense fast hydrogen atom beam of 300 kW power has been obtained with a new type of ion source, the periplasmatron. Source and neutral beam operation parameters are given.

Microwave plasma source as an ion beam neutralizer

Review of Scientific Instruments, 2004
A 13.56 MHz radio-frequency (rf) driven multicusp ion source has been developed at the Fast Neutron Research Facility. An argon ion current density of 29 mA cm−2 can be obtained for argon gas at a pressure of 0.4 Pa, rf power of 500 W and extraction voltage of 3 kV.

CONDITIONING OF THE JET NEUTRAL BEAM SOURCES

1989
The JET beam sources require several hundred beam pulses for conditioning up to 80 kV or 160 kV. Once conditioned, only some 30 pulses are required to recondition the sources after a shutdown of several weeks with the beam sources vented with atmospheric air.

Mathematical simulation of an inclined neutralization channel for a plasma source of neutral beams

Russian Microelectronics, 2009
An earlier developed model for a neutralization channel of a plasma source of neutral beams is applied to the case of an inclined neutralization channel. The energy and angular characteristics of the output beam are presented together with the neutralization factor as a function of the length and inclination angle of the channel.

Energy Distribution of Neutrals from a Hyperthermal Neutral Beam (HNB) Source

Journal of the Korean Physical Society, 2008
The energy distribution of the hyperthermal neutral beam (HNB) produced by impingement of plasma ions onto a metal surface was measured. A HNB source has been developed with a hotfilament discharge. The plasma was confined near the metal surface by using the magnetic field of a magnetron configuration.

Manufacturing of the full size prototype of the ion source for the ITER neutral beam injector – The SPIDER beam source

Fusion Engineering and Design, 2015
In ITER, each heating neutral beam injector (HNB) will deliver about 16.5 MW heating power by accelerating a 40 A deuterium negative ion beam up to the energy of 1 MeV. The ions are generated inside a caesiated negative ion source, where the injected H2/D2 is ionized by a radio frequency electromagnetic field.

Numerical simulation for the accelerator of the KSTAR neutral beam ion source

Review of Scientific Instruments, 2010
Recent experiments with a prototype long-pulse, high-current ion source being developed for the neutral beam injection system of the Korea Superconducting Tokamak Advanced Research have shown that the accelerator grid assembly needs a further upgrade to achieve the final goal of 120keV/65A for the deuterium ion beam. The accelerator upgrade concept was

Optimization of neutral beam injection in the beam plasma neutron source

Nuclear Fusion, 1995
The power efficiency of neutron production in the Beam Plasma Neutron Source (BPNS), proposed as a volumetric 14 MeV neutron source, is maximized at an energy of 110-120 keV for positive ion based (deuteron) neutral beams. Deuterons injected into a triton plasma and tritons into a deuteron plasma are shown to give equal results at the same injection ...

New ion source for KSTAR neutral beam injection system

Review of Scientific Instruments, 2012
The neutral beam injection system (NBI-1) of the KSTAR tokamak can accommodate three ion sources; however, it is currently equipped with only one prototype ion source. In the 2010 and 2011 KSTAR campaigns, this ion source supplied deuterium neutral beam power of 0.7–1.6 MW to the KSTAR plasma with a beam energy of 70–100 keV.
