Study on the production of hydrogen atomic beams by stripping negative hydrogen ions in a gas target

Abstract

The neutralization process and beam quality of a hydrogen beam prepared by emitting 1–––10 MeV negative hydrogen ions to a hydrogen target were studied. The simulation of the neutralization of negative hydrogen ions followed the construction of the neutralization theoretical model and beam transport model. Finally, calculations and analyses were performed to determine the effects of various variableson the neutralization of negative hydrogen ions, such as the transport distance, energy, and target gas density. According to the findings, since negative hydrogen ions in the target gas are transmitted farther, neutralization efficiency first rises and then falls. To achieve the highest neutralization efficiency, the gas vessel must be thicker depending on the incoming negative hydrogen ions are more energetic. Conversely, the denser the target gas, the thinner the gas vessel must be. The maximal neutralization efficiency, however, is unaffected by the density of the target gas or the negative hydrogen ion energy.
