It is generally believed that the Lawrence method of resonant acceleration of heavy particles is not applicable to electron acceleration due to relativistic variation of electron mass with its velocity. This difficulty is resolved in the accelerator proposed by Videroe and realized by Kerst. With Kerst apparatus 20 MeV energy electron beam is already obtained and evidently 100 MeV electron beams will be achieved soon. However, further increasing of electron energy by the Kerst method will
meet tremendous technical difficulties. It is worth to point out on one new possibility to obtain relativistic particles based on one simple generalization of the resonant method. (Extracted from the introductory part of the paper.).
