Generation of high current pulsed heavy ion beams using bi-directionaol pulses

Intense pulsed heavy ion beams (PHIB) of carbon, nitrogen, aluminum, etc., have a wide area of applications including nuclear fusion, materials science, etc. To produce a pure PHIB a new type of pulsed power ion accelerator is proposed. The accelerator consists of two acceleration gaps (an ion source gap and a post acceleration gap) and a drift tube and a bi-directional pulse is used to accelerate the ions. The concept of the accelerator is described with the principle to remove impurities. In addition, two types of pulse forming lines are proposed to generate bi-directional pulses for the accelerator. In the experiment, the bi-directional pulses of negative and positive pulse of duration 50 ns each are successfully generated by the proposed pulse forming lines.
