The design of free-electron lasers (FELs) based on submillimeter-range undulators involves difficulties associated with the fabrication of undulators with a very small period. To do this also requires accelerators with high-energy electron beams (>50 MeV). It should also be taken into account that these facilities use precision and expensive magnetic systems. In some works, an alternative FEL mechanism based on the use of the Smith-Purcell radiation (SPR) was considered. To realize the feedback in such an FEL, one must use a basically different cavity scheme. This work reports the results of experimental study on the stimulated SPR in a "transverse" cavity.
