title: Experimental non linear beam dynamics studies with a turn-by-turn phase space monitor at SPEAR
format: conference proceeding
conference: ICFA Workshop on Nonlinear and Collective Phenomena in Beam Physics
year: 1999

abstract: About 10 years ago the possibility of using turn-by-turn phase beam position monitors to gain insight into phase space dynamics of a single particle in a storage ring raised some interest among accelerator physicists. It was soon argued that Landau damping and collective effects would seriously complicate the interpretation of data. We have established that in SPEAR it is possible to lock a single bunch into a collective 'rigid body' mode. When in this mode the bunch will behave similar to a super particle of finite size with the charge equal to that of the bunch. In this paper we report on experiments that demonstrate this effect. We also numerically study the strong coupling limit, in which the transition to 'rigid body' motion occurs, for the two models proposed earlier. We present the experiments on non-linear resonance crossing and frequency map measurement in the 'super particle' framework. (11 References).

title: An X-ray transition radiation beam profile detector for the LCLS
format: conference proceeding
conference: ICFA Workshop on Nonlinear and Collective Phenomena in Beam Physics
year: 1999
2 authors: S. Monteiro | C. Pellegrini
abstract: We discuss the characteristics of a transverse beam profile detector for a high energy charged particle accelerator, and propose a candidate detector based on transition radiation in the X-ray region of the spectrum. The detector is useful for low emittance, high energy beams, for example, the LCLS electron beam. We expect that it can resolve spatial details as small as a few microns. The advantages of this method over previous ones are that the measurements are linear with the beam density and the results are a point by point map of the beam density. (14 References).
