Size Scaling of Negative Hydrogen Ion Sources for Fusion
The RF-driven negative hydrogen ion source (H , D ) for the international fusion experiment ITER has a width of 0.9 m and a height of 1.9 m and is based on a scale prototype source being in operation at the IPP test facilities BATMAN and MANITU for many years. Among the challenges to meet the required parameters in a caesiated source at a source pressure of 0.3 Pa or less is the challenge in si...
متن کاملElectron and Ion Sources for Particle Accelerators
A brief introduction to electron and ion sources for particle accelerators is given. Concentrating on the basic processes for the production of these particles, thermionic and photocathode production of electrons and the processes in Penning and electron cyclotron resonance ion sources are covered. Finally, negative ions are discussed.
متن کاملReview of Negative Hydrogen Ion Sources High Brightness/high Current
Due to the development of reliable H ion sources, charge-exchange injection into circular accelerators has become routine. This paper reviews recent developments in negative hydrogen ion sources. The underlying physics, operating parameters and beam characteristics of selected sources will be described and compared. Figure 1: History of duoplasmatron and surface source development.
متن کاملDevelopment of Multi-mega Watt Negative Ion Sources and Accelerators for Neutral Beam Injectors
High energy and high power negative ion sources and accelerators have been developed for neutral beam (NB) injectors of future fusion machines such as International Thermonuclear Experimental Reactor (ITER). Using a 5-stage electrostatic accelerator, negative ion beam has been successfully accelerated up to the energy of 1 MeV, which is the required energy for ITER. Powerful negative ion beams ...
متن کاملSimulation of diatomic gas-wall interaction and accommodation coefficients for negative ion sources and accelerators.
Particle-wall interactions determine in different ways the operating conditions of plasma sources, ion accelerators, and beams operating in vacuum. For instance, a contribution to gas heating is given by ion neutralization at walls; beam losses and stray particle production-detrimental for high current negative ion systems such as beam sources for fusion-are caused by collisional processes with...
