A Continuous Wave Millimeter Free Electron Laser Experiment With A Cockcroft-Walton Accelerator And Electron Beam Recovery

Problems relevant to a continuous wave Free Electron Laser (FEL) in the centimeter - millimeter region are investigated. The ideas are applied to the FEL experiment in progress at the Legnaro (Padova) INFN laboratory. The accelerator characteristics and laser parameters are briefly discussed. The laser could sweep the centimeter - millimeter region until 2.5 mm with a power around 15 kW.
