The electron laser facility (ELF) at LLNL has been used to generate high peak powers at 140 GHz, extending the operating range of the device from previous experiments at 35 GHz. With 30 W of input signal, an exponential gain of 21 dB/m and a saturated output power of over 50 MW were measured. Numerical tapering studies indicate that space charge effects at 3.5 MeV were sufficiently large to affect trapping efficiency. Broadband spontaneous emission was observed over a wide range of wiggler fields at frequencies corresponding to FEL resonance. Over 150 MW of spontaneous power was measured near 94 GHz. The results are in good agreement with particle simulation codes. |
