NEUTRAL BEAM SOURCE COMMERCIALIZATION STUDY: FINAL REPORT [PDF]
, 1980 The basic tasks of this Phase II project were to: generate a set of design drawings suitable for quantity production of sources of this design; fabricate a functional neutral beam source incorporating as many of the proposed design changes as proved feasible; and document the procedures and findings developed during the contract.

ARC SNUBBERS NEUTRAL BEAM SOURCES [PDF]
, 1979 At LBL it has been observed and verified many times that the amount of 1/2 CV{sup 2} energy associated with the accel grid that a neutral beam source can tolerate under sparkdown conditions is quite limited. If this energy exceeds approximately 5-7 Joules, serious degradation of the voltage holding capability of the source occurs.

The Full-Size Source and Injector Prototypes for ITER Neutral Beams [PDF]
Plasma and Fusion Research, 2016 Two Neutral Beam Injectors (NBI) will provide a substantial fraction of the heating power necessary to ignite thermonuclear fusion reactions in ITER. The development of the NBI system at unprecedented parameters (40 A of negative ion current accelerated up to 1 MV) requires a strong demonstration activity, which was endorsed by ITER to optimise the ...

Modelling the neutralisation process in neutral beam injectors [PDF]
, 2009 High power neutral beams currently play an important role in heating, fuelling and diagnosing magnetically confined thermonuclear fusion plasmas. At the Joint European Torus (JET) in Oxfordshire, England, the formation of such a beam involves passing a ...

Studia Universitatis Babes-Bolyai Chemia, 2021 Lead isotopic ratio determination is significantly affected by the isobaric interference of mercury (204Hg), thus many studies lack 204Pb/206Pb values. Removal of 204Hg from sample is resource consuming, while mathematical correction can be employed if ...

New source of MeV negative ion and neutral atom beams [PDF]
Review of Scientific Instruments, 2015 The scenario of “electron-capture and -loss” was recently proposed for the formation of negative ion and neutral atom beams with MeV kinetic energies. However, it does not explain why the formation of negative ions in a liquid spray is much more efficient than with an isolated atom.
