Using the Multirhodotron as an Advanced Rhodotron

This article assesses the use of a new type of electron accelerator, the Multirhodotron, for four new purposes that cannot be implemented using Rhodotrons and linacs. This study awards some arguments about possible replacement of nuclear reactors by electron accelerators in process of producing of medical isotopes on a global scale, about new possible electron accelerator for high energy, also describes new possibilities of actuation of free-electron lasers (FEL) at the megawatt level in the continuous wave (CW) mode, and suggests some decision of the use of Multirhodotron for technology of electron cooling in proton accelerators and colliders. Key words: Multirhodotron; Rhodotron; electron accelerator; powerful FEL; medical isotopes, electron cooling.
