    "abstract": "The equations describing the VFEL lasing in case of an electron beam moving\neither in a split of a diffraction grating or in a vacuum waveguide containing\na diffraction grating (vacuum VFEL) have been obtained. The dispersion equation\nallowing to find the vacuum VFEL gain in one-mode generation regime have been\nconsidered. It is shown that the vacuum VFEL amplification and the generation\nprocess develop more intensively then in ordinary FEL using one-dimensional\ndistributed feedback. Such the VFEL, if realised, could be made with much more\ncompact device structure compared with the FEL and therefore, may be\ninteresting for applications in different wavelength ranges: from submillimeter\nto X-ray. Such the VFEL can be realised on the basis of the existing\naccelerators.",
