A photon collider testbed at SLAC

Abstract:
An option for a photon collider interaction region is include in all
proposals for future TeV Linear Colliders.  Recent progress
in the conceptual design of the required lasers and optics have reached
the point where prototyping is the next step.  As the only existing linear
collider, the SLC presents an opportunity to demonstrate gamma-gamma
luminosity and gain operational experience with photon colliders.  Given
the interest in running SLC as a testbed for the NLC interaction region, we
propose installing a laser in the SLD hall and replacing the SLC beampipe
with one which includes focusing optics for the lasers.
