The authors report the status of a collaborative research project being developed, which is aimed at the construction of an IR free-electron laser (FEL) based on the EN tandem electrostatic accelerator of the Weizmann Institute of Science. A preliminary feasibility demonstration project yielded encouraging progress in three areas: (1) Electron gun and accelerator conversion: A 50-kV 1-A electron gun injector was designed, built, tested, and assembled on the 6-MeV tandem accelerator. (2) Electron-beam transport: The first installation of the electron optical beam recovery system yielded transport efficiency of 80%. (3) Wiggler development: A conventional 4.4-cm-period SmCo planar wiggler was acquired and evaluated using a recently constructed floating-wire magnetic field measurement setup. In addition, a microwiggler development program was launched.
