Generation of Heavy Ion Beams

Experimental results are presented concerning the acceleration of heavy ion beams generated in a planar diode and in a magnetically insulated strip diode by means of explosive emission. In case of carbon ions, by application of two voltage pulses (for plasma generation and ion acceleration, respectively) separated by an optimized pause, and by beam focusing current densities of 200 A/cm2, currents of 3 to 4 kA and beam divergences of less than 4± could be achieved.
