The six-dimensional beam phase space at the exit of a photoinjector can be completely characterized by means of an RF deflector and a dispersive system.

Abstract

The six-dimensional beam phase space at the exit of a photoinjector can be completely characterized by means of an RF deflector and a dispersive system. In this paper we summarize the main features of the use of an RF deflector to measure aspects of the longitudinal and transverse phase space in an ultra-short electron beam. In particular we illustrate these measurements through the simulation of experiments currently under development at the SPARC photoinjector. We also discuss the design procedure followed to design the RF deflector for SPARC. This device is a five-cell structure operating on the pi mode at 2.856 GHz. Finally, we report and discuss the cold-test measurement results on a full scale aluminum prototype. (c) 2006 Elsevier B.V. All rights reserved.
