Abstract :
We proposed that a new type of the electrostatic microwiggler with a wiggler period (0.1 mm ≤ lw ≤ 1 cm) and the wiggler field strength (Ew ≤ 500 kV/m) can be produced on the surface of a PZT when a high power and high frequency ultrasonic wave travels through a PZT bar. Numerical simulations in the linear and nonlinear gain regime show that a weak microwiggler (Ew = 500 kV/m, λw = 3 mm, 100 periods), operating in magnetoresonance with a strong guide field (B0 = 2 T), can generate millimeter and submillimeter radiations with medium electronic efficiency of few percents. It is shown that the maximum output power of the compact FEL using the wiggler system generated on the surface of the piezoelectric material may be up to a few watts with a relatively low energy and low current electron beam (Eb = 100 keV and Ib = 10 mA).
