A negative ion source for alkali ions [PDF]

Nuclear Instruments and Methods, 1980
An ion source is described which delivers negative alkali ions. With this source, which consists of a duoplasmatron and a charge exchange canal with alkali vapour, negative Li, Na and K ions are produced.

Response of negative ion beamlet width and axis deflection to RF field in beam extraction region [PDF]

Scientific Reports
Beam-divergence characteristics of single negative ion beamlet have been experimentally investigated with a superimposition of a controlled perturbation of a radio frequency wave (RF) field in a filament-arc discharge negative ion source. Oscillations of

Negative ion sources [PDF]

Journal of Applied Physics, 2021
In this Tutorial, surface and double charge exchange negative ion sources for producing negative ion beams of different ion species will be described. The need for negative ions as the beam particles of tandem Van de Graaf accelerators and that for charge exchange injection of hydrogen negative ions into high-energy proton accelerators requires the ...

High-intensity negative ion sources [PDF]

Nuclear Instruments and Methods, 1963
The production of beams of negative deuterium ions was studied with two ion sources with geometries that could be employed in a cyclotron. The negative ions were extracted directly from the arc in a direction normal to the magnetic field without using a charge-exohange medium. With a high gas pressure in the arc and an arc current of 5 amp, a 2-ma beam

Characterization of the RF plasma in negative ion source NIO1 [PDF]

, 2022
The NIO1 experiment is a negative ion source built at Consorzio RFX, Padua, with the aim to investigate and optimize the negative ion production. With this purpose, a diagnostic of the plasma in the NIO1 source is essential.

Experimental evaluation of a negative-ion source for a heavy-ion fusion negative-ion driver [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
Abstract Negative halogen ions have recently been proposed as a possible alternative to positive ions for heavy-ion fusion drivers because electron accumulation would not be a problem in the accelerator, and if desired, the beams could be photodetached to neutrals (Nucl. Instr. and Meth. A 464 (2001) 315; Fusion Sci. Technol.

Diagnostics for negative ion source NIO1 [PDF]

, 2022
The development of Neutral Beam Injectors (NBI) as auxiliary heating systems for ITER, the experimental reactor that will be realized in Cadarache (France), is a fundamental topic of the fusion science research in the last decades. For this purposes much

Research progress of electrospray ion source principle [PDF]

, 2022
The theory of ion source is of great significance to the design and development of ion source, the slow development of this restricts the design and development of ion source, which makes the ion source meet many bottlenecks from laboratory to ...

First experiments with the negative ion source NIO1

Review of Scientific Instruments, 2015
Neutral Beam Injectors (NBIs), which need to be strongly optimized in the perspective of DEMO reactor, request a thorough understanding of the negative ion source used and of the multi-beamlet optics. A relatively compact radio frequency (rf) ion source, named NIO1 (Negative Ion Optimization 1), with 9 beam apertures for a total H− current of 130 mA ...
