Summary:Title screen
The energy deposition of intense pulsed ion beam (IPIB) in stainless steel was studied with ion beamgenerated by a magnetically insulated diode (MID). By taking space charge limitation approximation withChildeLangmuir (CeL) Law, combining with the time-of-flight (TOF) method, the temporal structure ofthe energy spectrum of IPIB was analyzed. When comparing with the experimental data, the dynamicenergy spectrum of IPIB composed of protons and C? ions, pulsed duration of 80 ns (FWHM), particleenergy up to 420 keV and current density over 200 A/cm2 can be well described with this method.Combined with Monte Carlo method and infrared imaging diagnostics, this dynamic energy spectrumwas further utilized to calculate the power density distribution of IPIB in stainless steel. The results wereapplied to thermal field simulation, and the influence of IPIB dynamic energy spectrum on the thermalresponse of the target was discussed.
