DIAGNOSTIC TECHNIQUE FOR PULSED HIGH-CURRENT RELATIVISTIC ELECTRON BEAM IN LINEAR INDUCTION ACCELERATOR Russian patent published in 2016 - IPC G01T1/00 

FIELD: physics.

SUBSTANCE: invention relates to acceleration engineering, namely to diagnostic techniques for transfer of pulsed high-current relativistic electron beams (PHCREB) in powerful linear accelerators. Diagnostic technique for a pulsed high-current relativistic electron beam in a linear induction accelerator duct involves detecting the amplitude and shape of the beam current pulses using induction current sensors and integral values of deceleration radiation doses on the duct walls with the help of thermoluminescent dosimeters increasing in quantity the current sensors number and installed along the duct, by analyzing the obtained information conclusions are made on the change of equilibrium state of the beam associated with amplitude-time variations of the beam current pulses, and areas and levels of the beam electronic losses on the duct walls are determined, herewith measuring devices are added with a set of scintillation detectors of deceleration radiation with nanosecond resolution while locating them nearby the thermoluminescent dosimeters and registering the amplitude and shape of pulses with the scintillation detectors, calibrating them by integral dose with the thermoluminescent dosimeters, comparing the amplitude and shape of pulses from the scintillation detectors and from the current sensors and the results of the comparative analysis additionally demonstrate the change of levels of electronic losses of the pulse high-current relativistic electron beam on the duct walls for the current pulse duration during passage of the beam along the acceleration duct.

EFFECT: higher information content of the diagnostic technique for a high-current relativistic electron beam in a linear induction accelerator.
