The gamma-gamma working group of ALCPG will hold a workshop at SLAC on a proposal for a photon collider test facility on November 21-23, 2002. A draft of the proposal can be found at http://www.slac.stanford.edu/~gronberg/SLC-gg_draft.pdf the workshop website is available at http://www-conf.slac.stanford.edu/lepcf/ Topics to be discussed include: Photon Collider physics at a future LC The potential for a low energy photon collider demonstration to increase confidence in the technical feasability of a photon collider facility at a future LC. Detailed discussions on the requirements for a photon collider demonstration at SLC including: Laser and Optics hardware. Current status of SLC and requirements for its revival. Observation of gamma-gamma luminosity using SLD or other detectors. A roundtable discussion of the timescales for decisions about the project scope of a future LC and whether a photon collider test facility can have an impact on those decisions. The possibility of photon collider experiments at sub-LC energies. Participants are kindly requested to register at the website so that we may have a head count for coffee and doughnuts.
