WebEven if the ion beam potential is sufficient to produce neutralization arcs, the departure from equal numbers of electrons and ions in each volume would be small. Current … WebION BEAM NEUTRALIZATION WITH FERROELECTRICALLY GENERATED ELECTRON BEAMS U. Herleb and H. Riege CERX, LHC Division. CH-1211 Genera 23. Switzerland Abstract A technique for ion beam space-charge neutralization with pulsed electron beams is described. The intensity of multiply-charged ions produced with a laser ion … Web17 aug. 2024 · Neutralization of the ion beam space charge by bulk electrons could decrease the ion beam radius, producing an increase in the ion current greater than in the absence of plasma. A larger α corresponds to a higher electron density, whereas a smaller α corresponds to a lower electron density or background gas condition. how does an axolotl regenerate
