Issues in storage-ring for operation of high-gain FELs

PDF Version Also Available for Download.

Description

A high-gain free electron laser (FEL), placed in a special by-pass of a storage ring, can provide tens of magewatts of coherent power at wavelengths shorter than 1000 A. The requirements on beam quality, (few hundred amperes of peak current, emittance of the order of 10/sup -8/ m-rad, and relative energy spread less than 0.002) are demanding but lie within the limits of modern storage ring technology. In this paper, we study various issues in storage ring design and FEL physics for operation of a high-gain FEL. Topics included are the requirements on beam parameters for FEL operation, coherent instabilities ... continued below

In this paper, we study various issues in storage ring design and FEL physics for operation of a high-gain FEL. Topics included are the requirements on beam parameters for FEL operation, coherent instabilities and intrabeam scattering effects in the storage ring, lattice design, and FEL performance computered by 2-D simulations.
