Formation of the characteristics of ion emission from a laser-produced plasma in the presence of a conducting diaphragm

The effect of electrical diaphragm-target coupling on the formation of ion component characteristics of a laser-produced plasma is considered. When the target and the diaphragm are insulated from each other and are under a floating potential, a high-energy ion peak is observed and the integral number of ions and their multiplicity increase compared to the case when the target and the diaphragm are connected and grounded.
