Development of electrostatic multistage accelerator for high current pulsed ion beam
説明
Two types of electrostatic linear accelerators (type A and B) are proposed as a substitute for an induction linac to accelerators a high current pulsed ion beam. In type A sufficiently long acceleration tubes compared to the ion beam is used, inside of which multi-stage acceleration gaps are placed. Square pulses are sequentially applied to the acceleration gaps where the beam is passing and compensating voltages are applied to the gaps where the beam is absent to realize multistage acceleration without increasing the beam potential. On the other hand, in type B, bi-directional pulses are utilized which are sequentially applied to the acceleration gaps to realize the multistage acceleration. Compared to ion beam induction linacs, the proposed accelerators are simple, low cost and a higher acceleration gradient is expected since magnetic cores or induction cells are not utilized. Electrical behaviors of both systems are numerically simulated and demonstrated. In addition, two types of pulse forming lines are proposed to produce bi-directional pulses for the type B accelerator. The performance of the lines was demonstrated numerically and experimentally.
