Measurement of γγ and γe luminosities and polarizations at photon colliders
Methods of γγ, γe luminosities measurement at photon colliders based on Compton scattering of laser photons on high energy electrons at linear colliders are considered. This is not a simple problem because photon have broad spectra and various kind of polarizations.
