Abstract
Design criteria for multipulse operation of a multisection pulse line ion accelerator
Highlights
The pulse line ion accelerator (PLIA) [1] offers the possibility of a low-cost linac for the acceleration of nonrelativistic ions
We make the following observations regarding this application: (i) The total required voltage to reach the final energy is 4.25 MV. (ii) The average current is low, and space charge effects are less severe than the typical HIFVNL high energy density physics (HEDP) application [8]. (iii) The incoming energy is almost identical to the PLIA experiment at NDCX, and the first bunching section proposed in this design is very similar to Roy et al [9]
We show that multipulse operation of a pulse line ion accelerator through a long linac with multisections is possible
Summary
The pulse line ion accelerator (PLIA) [1] offers the possibility of a low-cost linac for the acceleration of nonrelativistic ions. It was originally motivated by the need to use moderate energy intense ion beams to heat matter to regimes of interest for studies of high energy density physics (HEDP) and warm dense matter [2 – 4]. It would be desirable to accelerate a long train of ions at up to tens of microseconds This would be possible if one could operate PLIA in a multipulse, multisection mode with a ringing circuit. We consider the beam dynamics of such an accelerator, and derive a set of criteria for designing an accelerator with multiple sections, using PLIA structures
