title: Free electron laser experiment at the NSLS 700 MeV electron storage ring
format: conference proceeding
conference: PAC 1981
year: 1981
11 authors: J. P. Blewett | L. Blumberg | A. J. Campillo | R. P. DiNardo | H. C. Hsieh | S. Krinsky | A. Luccio | C. Pellegrini | J. Schuchman | P. Z. Takacs | A. van Steenbergen
abstract: A free electron laser experiment is described, to be performed with the 700 MeV electron storage ring of the National Synchrotron Light Source. The experiment is designed to study the parameters of the fel in an electron storage ring and the performance of this laser as a source of short wavelength radiation in the VUV region of the spectrum. The initial experiment will be carried out at a wave length of approximately 3000 AA, utilizing a permanent magnet undulator. For an average electron current of 1 A distributed in three beam bunches, the small signal gain per pass (relative enhancement of the radiation intensity per electron bunch pass through the undulator) is calculated to be approximately 10%.

title: Longitudinal instabilities in circular accelerator and storage rings
format: conference proceeding
conference: PAC 1981
year: 1981
1 author: C. Pellegrini
abstract: Coherent instabilities of particle beams in circular accelerators and storage rings have been the subject of many theoretical and experimental works. The coherent instabilities discussed are produced by the electromagnetic interaction of the charged particle beam with the walls of the vacuum chamber in which the beam is moving. The author reviews the general problem of the longitudinal stability of bunched beams. Although there is no general solution it is possible to identify regions in the frequency-risetime space where one can obtain approximate solutions. An expression for the collective oscillation frequency is presented and expressions for the effective coupling impedance are given for the high or low frequency and slow and fast blow-up regimes.
