摘要: Apparatus for neutralization of a beam accelerated ions, such as hydrogen negative ions (H - ), using relatively efficient strip diode lasers which emit monochromatically at an appropriate wavelength (λ = 8000 A H ions) to the excess electrons by photodetachment. cavity, formed two or more reflectors spaced apart, causes laser beams undergo multiple reflections within thus increasing efficiency and reducing illumination required obtain acceptable percentage (˜ 85%) neutralization.
