Dynamic energy spectrum and energy deposition in solid target by intense pulsed ion beams

Abstract

A method for analyzing the dynamic energy spectrum of intense pulsed ion beam (IPIB) was proposed. Its influence on beam energy deposition in metal target was studied with IPIB produced by two types of magnetically insulated diodes (MID). The emission of IPIB was described with space charge limitation model, and the dynamic energy spectrum was further analyzed with time-of-flight method. IPIBs generated by pulsed accelerators of BIPPAB-450 (active MID) and TEMP-4M (passive MID) were studied. The dynamic energy spectrum was used to deduce the power density distribution of IPIB in the target with Monte Carlo simulation and infrared imaging diagnostics. The effect on the distribution and evolution of thermal field induced by the characteristics of IPIB dynamic energy spectrum was discussed.
