The Israeli FEL is one out of few projects in the world which are based on electrostatic accelerators. Only such devices can operate with a continuous wave (cw) or in a quasi-cw (long pulse) mode. All other FELs, are based on pulsed accelerators and can produce, therefore, only a pulsed waveform. Electrostatic Accelerator FELs (EA-FEL) are also characterized by potential for high average power, high energy conversion efficiency and high spectral purity (narrow linewidth).

The eccelerator development work and the subsequent FEL experiment were funded by the Israeli Ministry of Science, Ministry of Energy and Infrastructure and Ministry of Defence, the Israel Academy of Science, U.S.-Israel B.S.F. and the Meyer Foundation.

The project is carried out by a consortium of 3 institutes: Tel-Aviv University, RAFAEL and Nuclear Research Center Negev.
