Abstract;Recently, the JAERI superconducting rf linac based FEL has successfully been lased to produce a 0.3kW FEL light and 100kW electron beam output in quasi continuous wave operation. The 1kW class output as our present program goal will be achieved to improve the optical out coupling method in the FEL optical resonator, the electron gun, and the electron beam optics in the JAERI FEL driver. As our next 5-year program goal is the 100kW-class FEL light and multi-MW class electron beam output in average, quasi continuous wave operation of multi-MW electron beam will be planned in the JAERI superconducting rf linac FEL driver facility. Conceptual design options needed for such a very high power operation will be discussed to improve and to upgrade the existing facility. (author abst.)
