The Detector and Interaction Region for a Photon Collider at TESLA

Abstract

TESLA is designed as an electron-positron linear collider (LC) based on super-conducting technology. A second interaction region is forseen to be incorporated in the design allowing its possible operation as a photon collider. In this paper I describe the basic design of the $\gamma \gamma$ interaction region taking into account the beam-beam and laser related issuses and review some aspects of other accelerator components such as the feedback system and the beam dump which are critical to the operation of TESLA as a photon collider.Comment: Talk presented at HEP03 conference, Aachen, July 2003, 3 pages, 4 figure
