Abstract
The interaction of a pinched relativistic electron beam with a solid target is calculated by use of the Monte Carlo method for energy deposition and two-dimensional particle-in-cell (PIC) hydrodynamics to take into account the full effect of target expansion. Bremsstrahlung emission is also evaluated through the use of the Monte Carlo method. Self-magnetic-field effects are neglected. It is found that target expansion can considerably reduce the efficiency of energy deposition in the focal region.
