Abstract.

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 demonstration project for the higher-energy two-beam accelerator CLIC. CLICHE is conceived as a factory capable of producing around 20,000 light Higgs bosons per year. We discuss the requirements for the CLIC 1 beams and a laser backscattering system capable of producing a \(\gamma \gamma\) total (peak) luminosity of \(2.0 (0.36) \times 10^{34}\) cm-2s-1 with \(E_{CM}(\gamma \gamma) \sim 115\) GeV. We show how CLICHE could be used to measure accurately the mass, \(\bar b b\), 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 supersymmetric and more general two-Higgs-doublet models, complement ing the measurements to be made with other accelerators. We also comment on other prospects in \(\gamma \gamma\) and \(e^- \gamma\) physics with CLICHE.
