Phasotron ( from phase + electron ), synchrocyclotron ( from synchronization + cycle + electron ) is a cyclic accelerator of heavy charged particles ( protons , deuterons , ions , etc.), in which the magnetic field is uniform and constant in time, and the accelerating frequency electric field is changing.
In high energy physics, this type of accelerator is considered obsolete, but it is still used, for example, in medicine [1] .
In the summer of 2014, the synchrocyclotron was launched at CERN [2] .
Principle of Operation
In their basic features, the principle of operation and the arrangement of the synchrocyclotron are the same as for the cyclotron . The difference is the compensation of the effect of relativistic delay [3] by a corresponding decrease in the frequency of the accelerating field.
The synchrocyclotron operates in the mode of repeating acceleration intervals with a certain frequency. The frequency of the accelerating electric field in the working part of each interval decreases in accordance with the particle energy, and at the end of the interval returns to its initial value.
This principle is reflected in the name of the accelerator - synchro cyclotron.

- ↑ With increasing particle velocity according to SRT , their mass increases, which leads to a slowdown in their acceleration.
