  The single production of top quark due to flavor changing neutral current
(FCNC) interaction and its decay to bW are studied at CLIC+LHC based gamma-p
colliders. We consider both t-c-gamma and t-u-gamma anomalous couplings. The
anomalous charm (up) quark anomalous coupling parameter kappa_gamma^c
(kappa_gamma^u) can be probed down to 9.5x10^-3 (8.0x10^-3) at a gamma-p
collider with sqrt{s_ep}=6.48 TeV and L_int=100 fb^-1.
