Abstract

In this experimental work, a new and very compact home made XeCl laser has been used for the ion beam generation by metallic targets. Multiply-charge heavy ion pulses have been extracted by the plasma produced by a focused laser beam at relatively low flux (approximately 30 MW/cm2) on Si, Ge, Mg and Zn targets. An output peak current of Si3+ ions of 375 mA has been recorded at an acceleration voltage of 200 V only. The insertion of a variable capacitance between the target holder and the acceleration electrode allowed a self-bunching of the ion beam. Besides, a peak current of 1.4 A of Pb3+ ions was obtained by increasing the laser flux to 86 MW/cm2 and the acceleration voltage to 500 V.
