Free-electron laser generation of VUV and x-ray radiation using a conditioned beam and ion-channel focusing

摘要

The use of ion-focusing and a conditioned beam greatly enhances FEL gain in the VUV and Soft X-Ray range. The equations governing FEL amplification are derived and results of a linear analysis are noted. Numerical results, including 3D effects and having an order of magnitude improvement in gain, are presented for a 30 (Angstrom) example. 3 refs., 2 figs., 1 tab.
