Abstract
Official abstract text for this publication.
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 (R 56 >0), and 3) compensating for aberration by using nonlinear magnets in the compressor beam line.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for compressing the bunch length of a free electron laser (FEL) comprising: a. providing an FEL including an RF waveform with a falling portion; b. applying acceleration on the falling portion of the RF waveform; c. compressing using a positive momentum compaction (R 56 >0); and d. applying aberration compensation. 2. The method of claim 1 wherein the aberration compensation is applied by one or more nonlinear magnets in a compressor beam line. 3. The method of claim 1 wherein the aberration compensation is applied by one or more sextupole magnets in a compressor beam line.
