A free-electron laser FEL which will be driven by the cw racetrack microtron RTM, will be operated as an oscillator with the fundamental wavelength variable from approximately 200 nm to 10 micrometers. The presence of harmonics should allow for operation in the VUV and EUV spectral regions. The cw RTM consists of a 5 MeV injector section and a 12 MeV, cw, rf linear accelerator linac. The linac is placed between two uniform-field end magnets that recirculate the beam on successive orbits through the linac. The beam can be deflected out of the RTM after completing up to and including 15 passes through the linac, so that the final beam energy is 17 MeV to 185 MeV. As a FEL driver, the unique features of the RTM are the cw nature of the beam, excellent energy stability, small values of the transverse emittance and energy spread, and high average power.
