Title: Status of the advanced photon source low-energy undulator test line

Conference ·
OSTI ID:554151

The low-energy undulator test line (LEUTL) is being constructed at the Advanced Photon Source (APS). Its first purpose is to fully characterize innovative, future generation undulators, some of which may prove difficult or impossible to measure by traditional techniques. Second, LEUTL will act as a test line to investigate the generation of coherent radiation at wavelengths down to a few tens of nanometers. The line will use a high-brightness rf electron gun as its source and the APS linac to accelerate these electrons up to >650 MeV. This beam will then be directed into a new enclosure that is nearly 50 m long and will accommodate beamline components, diagnostics, and undulators. This region is wide enough to house two separate beamlines. In addition, there is an external end station appropriate for housing the equipment necessary to directly study the generated light outside of the radiation environment. At present, the new enclosure and building are complete, the new rf electron gun is installed and operational, and a part of the necessary transport line is installed. An undulator cell prototype, suitable for testing the requirements of single-pass free-electron laser operation, is near completion and will be installed during the winter shutdown of 1997. This paper will describe the LEUTL project and its capability for exploring the self-amplified spontaneous emission process.
