Abstract
It is proposed to use multi-stage FEL amplifier with a diaphragm focus ing line as direct energy driver for inertiaI confinement fusion. The driving beam for the FEL amplifier is generated by the linear inductio n accelerator. The laser system operates at a radiation wavelength of 0.5 mu m with the total energy of laser Hash of 1.5 MJ, pulse duration of 4 ns and repetition rate of 40 pulses per second. Total efficiency (i.e. conversion efficiency of net electrical power to the radiation power) of the proposed system is equal to 12%. The brightness of the o utput radiation is 10(22) W/cm(2) sr. The scale and the cost of the FE L based energy driver are close to those of the heavy ion fusion drive r.
