Abstract
A method of bunch length compression method for a free electron laser (FEL) that avoids parasitic compressions by 1) applying acceleration on the falling portion of the RF waveform, 2) compressing using a positive momentum compaction (R56>0), and 3) compensating for aberration by using nonlinear magnets in the compressor beam line.
Claims3
