Abstract

The interaction of pinched relativistic electron beam with a thin bremsstrahlung target is calculated by use of the Monte Carlo method for energy deposition and two-dimensional particle- in-cell hydrodynamics to take into account the effects of target expansion and magnetic field penetration. It is found that bremsstrahlung efficiency increasing, converter optimum thickness decreasing and bremsstrahlung spectrum softering occur due to magnetic stopping in low density target. The automodel solution of plasma motion is considered.
