Conversion efficiency of heat flux into hard x-ray radiation

The conversion efficiency of a heat flux into hard X-ray radiation is analyzed for a heat-to-radiation flux converter linked to the edge of low atomic number hot Z-pinch using a time-dependent two-temperature one-dimensional non-LTE-radiation-hydrodynamic numerical model. The model gives a parameter regime with about the same hard x-ray yield as a radially imploding plasma, but with an order of magnitude lower input energy.
