Higgs Physics with a gamma-gamma Collider Based on CLIC 1

We present the machine parameters and physics capabilities of the CLIC Higgs Experiment (CLICHE), a low-energy gamma-gamma collider based on CLIC 1, the demonstrator project for the higher-energy two-beam accelerator CLIC. CLICHE is conceived as a factory capable of producing over 10,000 light Higgs bosons per year. We discuss the requirements on the CLIC 1 beams and on a laser backscattering system capable of producing a gamma-gamma total luminosity of 8 x 10^33 cm^-2s^-1 with a center of mass energy of about 120 GeV. We show how CLICHE could be used to measure accurately the mass, bbar WW and gamma gamma decays of a light Higgs boson. We illustrate how these measurements may distinguish between the Standard Model Higgs boson and those in super symmetric and more general two-Higgs-doublet models, complementing the measurements to be made with other accelerators. We also comment on other prospects in gamma-gamma and e^-gamma physics with CLICHE.
