Tulupov}, title = {Cooling of Relativistic Electron-Beams}, abstract = {A method of reducing the energy spread of an electron beam in a free-electron laser is suggested. The electron beam compression is based on a nonlinear mechanism of electron interactions with a ponderomotive wave in the presence of a constant and uniform magnetic field perpendicular to the electron motion. Due to this interaction the electrons slightly increase their energies; electrons with less initial energy are subject to a higher acceleration. As a result, the initial energy spread can be reduced several times.}, year = {1993}, journal = {Nuclear Instruments & Methods in Physics Research Section a-Accelerators Spectrometers Detectors and Associated Equipment}, volume = {331}, number = {1-3}, pages = {332-334}, month = {Jul 1}, isbn = {0168-9002}, doi = {10.1016/0168-9002(93)90069-t}, language = {eng}, }
