Self-crowbar switch operation in small MITL

We tried reduction of low energy components in pulse ion beams with self-crowbar switch of which operation was achieved by expansion of electrode plasmas in a small MITL. The experiments were carried out with the small MITL (self-crowbar switch) and the “Inverse Pinch Ion Diode”. From the experimental results, the times required for dropping of pulse high voltage were shortened from 40 to 15 ns. As the result of this shortening, the ions accelerated at a relatively low voltage decreased, and the energy ranges of proton beams were reduced from 60 to 30 keV.
