Simulating beam parameter using Malmberg–Penning trap device for longitudinal pulse compression in heavy ion inertial fusion

A simulating beam parameter is considered in a compact beam simulator constructed with a Malmberg–Penning trap device for heavy ion inertial fusion. The Malmberg–Penning trap device is expected as an experimental device to simulate longitudinal pulse compression in a driver system for heavy ion inertial fusion. Tune depression is estimated with Brillouin density limit, rigid–rotor Vlasov equilibrium, and a model considering with radial distribution of charge density. As a result, it is considered that these estimations are not suitable for the space charge strength of the condition in the device. (author)
