Abstract

The use of a small period wiggler (l_w < 1 cm) together with a sheet electron beam has been proposed as a low cost source of power for electron cyclotron resonance heating (ECRH) in magnetic fusion plasmas and for space-based radar systems. We have experimentally demonstrated stable propagation of a sheet beam (18 A, 1 mm × 20 mm) through a ten-period wiggler electromagnet with peak field of 1.2 kG. Calculation of microwave wall heating and pressurized water cooling have also been carried out, and indicate the feasibility of operating a near-millimeter, sheet beam FEL with an output power of 1 MW CW (corresponding to power density into the walls of 2 kW/cm²). Based on these encouraging results, a proof-of-principle experiment is being assembled, and is aimed at demonstrating FEL operating at 120 GHz with 300 kW output power in 1 µs pulses; electron energy would be 410 keV. Preliminary design of a 300 GHz, 1 MW FEL with an untapered wiggler is also presented. Finally, a method of modulating high power CW signals for radar applications is suggested.
