Abstract
The ROKK-1M facility generates high energy polarized gamma-ray beams b y backscattering of laser light against the high energy electron and p ositron beams of the VEPP-4M collider. The facility design allows to o btain backscattering of laser light on electron and positron beams sep arately or simultaneously. Tagging and/or collimation is applied to se lect a narrow energy band from the gamma-quanta spectrum. Operating in a laser polarimeter mode, the ROKK1-M facility is able to measure tra nsverse and longitudinal polarization of the electron and positron bea ms in the VEPP-4M collider. A description of the facility and achieved gamma-ray beam parameters are presented in this paper. (C) 1998 Elsev ier Science B.V. All rights reserved.
