Acceleration of electrons in classical cyclotron

It is suggested that electrons as well as ions can be accelerated in a classical cyclotron. Such electron acceleration becomes possible when the cyclotron enters the microtron mode, The attainable energy of the electrons in cyclotrons with polar diameter from 1,2 to 1.5 m may amount to 30 to 50 MeV (the maximal energy of ions in existing microtrons amounts to 32 MeV). Electron acceleration in the quasi-continuous mode is possible.
