摘要：
The performance of a staggered-array wiggler for the far infrared free-electron laser (FIRFEL) project at Stanford has been characterized analytically and experimentally. A 10.8 kG peak wiggler field was measured for a 2.0 mm gap and a 1.0 cm wiggler period at a 7.0 kG solenoid field. The wiggler field uniformity was investigated by the pulsed-wire technique, and measurements showed a 1.2% rms field variation over a 50 cm wiggler section. With fairly simple design schemes, studies indicate the velocity drift in a staggered wiggler can be eliminated.
