On the path to the next generation of light sources

PDF Version Also Available for Download.

Description

At the Fourth Generation Light Source Workshop in January 1996, storage-ring-based FELs and linac-based FELs were considered for VUV/soft x-ray and hard x-ray ({lambda} {approximately} 1 {angstrom}) photon production, respectively. The general requirements of a diffraction-limited source--bunch lengths less than 1 ps (100 fs in case of the linac-based source), coherence, and a brightness several orders of magnitude brighter than third-generation sources--were among the features discussed. Examples of progress in demonstrations, measurements, or calculations that support research towards these areas are cited. These range from the 50-fs bunch length measurement at low current in a linac to few-{micro}rad divergence measurements ... continued below

These range from the 50-fs bunch length measurement at low current in a linac to few-{micro}rad divergence measurements on a 7-GeV storage ring. The possible extension of transition radiation beam characterization techniques to nonintercepting diffraction radiation is briefly addressed as well.
