Warm dense matter (WDM) conditions are to be achieved by combined longitudinal and transverse neutralized drift compression of an intense ion beam pulse to provide a hot spot on a target with a beam spot size of about 1 mm, and pulse length about 1-2 ns. The range of the beams in solid matter targets is about 1 micron, which can be lengthened by using reduced density porous targets. Initial experiments in ion-beam-driven WDM will be at low beam velocity, below the Bragg peak, increasing toward

... he Bragg peak in subsequent higher-energy accelerators. Initial experiments include a transient darkening experiment and a experiment in porous targets at GSI. Further experiments will explore target temperature and other properties such as electrical conductivity to investigate phase transitions and the critical point.
