Abstract
We report temporal and spatial phase measurements of a pulsed free ele ctron laser amplifier (FEL) operating in combined wiggler and axial gu ide magnetic fields. The system uses a mildly relativistic electron be am (750 kV, 90-300 A, 30 ns), and is excited by a high power 33.39 GHz magnetron source. The phase during the voltage pulse is measured by a n interferometric technique from which frequency chirping is determine d.
