  We investigate the radiation from a charged particle rotating around/inside a cylindrical grating. The expressions are derived for the electric and magnetic fields and for the angular density of the spectral-angular distribution of the radiation intensity. Two types of the radiation processes are realized: synchrotron and Smith-Purcell radiations. Their relative contributions to the total radiation intensity are discussed in various asymptotic regions of the parameters describing the diffraction grating and for large harmonics. The region of the parameters is specified for which the interference effects between the synchrotron and Smith-Purcell radiation is essential.
