TTP92-28 Heavy Quark Production at a Photon Linear Collider

Heavy quark production at future Compton colliders is investigated. The impact of polarization has been studied. Perturbative QCD corrections to the effective cross section are calculated and found to be at the level of 40\% for a $e^+e^-$ collider of 500 GeV and a top quark mass of 150 GeV. The $\eta_t$ resonance structure is incorporated.
