title:	Measurements of High Gain and Intensity Fluctuations in a Self-Amplified, Spontaneous-Emission Free-Electron Laser
format:	journal article
year:	1998
12 authors:	M. Hogan | C. Pellegrini | J. B. Rosenzweig | G. Travish | A. Varfolomeev | S. Anderson | K. Bishofberger | Pedro Frigola | A. Murokh | N. Osmanov | S. Reiche | A. Tremaine
abstract:	We report measurements of large gain for a single pass free-electron laser operating in self-amplified spontaneous emission (SASE) at 16 mm starting from noise. We also report the first observation and analysis of intensity fluctuations of the SASE radiation intensity in the high gain regime. The results are compared with theoretical predictions and simulations.

abstract:	A description of a new 2 m undulator is presented which was specially designed and manufactured for a SASE mode FEL experiment. It is a one section two plane focusing permanent magnet construction. The uniform period length is 2.06 cm, total number of periods is 98. The peak field on the axis is 5.4 kG for a 5 mm gap.
