SYNCHROCYCLOTRON PROTON ENERGY MONOCHROMATIZATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC H05H7/00 

FIELD: synchrocyclotron proton energy monochromatization devices.

SUBSTANCE: invention relates to a method and device for synchrocyclotron proton energy monochromatization. The method consists in implementing the output of the proton beam from the synchrocyclotron when the accelerating voltage from the dee is turned off and is carried out by the method for building up the amplitudes of proton oscillations before they are output from the synchrocyclotron. For this, an electrode is used - a deflector, to which a radio pulse is applied with a filling frequency corresponding to the spectrum of betatron radial oscillations of protons. In addition, the radio engineering units of the synchrocyclotron additionally include a radio pulse generator for the deflector and an associated unit for modulating its frequency and amplitude, as well as a control unit connected by communication circuits to the radio pulse generator, to the high-frequency voltage generator on the dee and to the dee.

EFFECT: increase in the degree of beam proton energy monochromatization ΔE/E ≈ 10^-4 without loss of fluence with a significant simplification of the device design.
