Abstract

Beam parameter requirements are estimated for generating warm dense matter (WDM) by means of an intense electron beam. An energy balance equation between input beam and energies distributed into a target is derived. Results show that a beam of lower kinetic energy has some advantages for WDM generation from the viewpoint of radiation loss and beam current. Results also indicate that WDM (2 mm × 2 mm) at 5000 K can be generated using an electron beam with parameters kinetic energy = 1 MeV, beam current = 2.3 kA, and pulse duration = 100 ns.

Keywords
