Results of first operation of the Israeli Electrostatic-Accelerator Tandem Free-Electron Laser (EA-FEL) are reported. This EA-FEL utilizes a 1.4 Amp electron beam obtained from a parallel flow Pierce-type electron gun. The e-beam is transported through a resonator located inside a planar Halbach configuration wiggler, both located at the high voltage terminal of the van de graaf accelerator. The high voltage terminal is charge to a positive potential of 1.4 MeV with respect to the cathode. The resonator utilizes a curved parallel plates waveguide and two Talbot effect quasioptical reflectors (wave splitters). It exhibited a quality factor of Q ≈ 30,000. Millimeter wave radiation pulses of 2 μsec duration were obtained at a frequency of 100.5 GHz, as predicted, at a power level above 1 kW.
