Development of Infrared Free Electron Laser System Using Compact Linac

摘要

The present status of infrared free-electron laser (FEL) system using compact linac in Sumitomo Electric Industries Ltd. (SEI) is reported. Characteristics of the beam transport system was studied through numerical simulations. For precise simulating, initial condition of the beam at the end of the linac was examined in details. As a result, beam transport condition to realize well-focused beam in undulator was obtained. Spontaneous emission of peak power of 0.4mW was observed in recent experiment.
