METHOD OF MEASURING ENERGY OF ACCELERATED ELECTRONS IN BETATRON Russian patent published in 2011 - IPC G01T1/29 

FIELD: physics.

SUBSTANCE: method involves conversion of voltage from a tracking coil on the pole of the betatron to voltage which repeats the form of the magnetic field on the equilibrium orbit and subsequent absolute calibration of the energy scale of the betatron during operation of the accelerator. By varying the injector filament current and delay time for applying a high voltage pulse across the cathode of the injector relative the moment current appears in the magnetising winding of the electromagnet of the betatron, maximum output of radiation from the accelerator is achieved, thereby determining optimum delay for applying an injection voltage pulse across the cathode of the injector.

EFFECT: simple method of determining maximum kinetic energy of electrons accelerated in a betatron.
