  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$^{-2}$s$^{-1}$ 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, complementing the measurements to be made with other accelerators. We
also comment on other prospects in $\gamma\gamma$ and $e^- \gamma$ physics with
CLICHE.
