Abstract

The invention discloses an X-ray energy measuring system for an accelerator, comprising an X-ray dosage detection device, a collection device and a discriminator, wherein the X-ray dosage detection device comprises a plurality of detectors which are arranged at intervals in parallel, wherein signals of adjacent detectors are isolated so as to prevent signal crosstalk between each detector; a collection device; and a comparison device which includes a storage unit for storing a standard absorption curve of a standard energy accelerator on the X-ray dosage detection device, wherein the X-ray detection device is exposed through a series of standard energy accelerators so as to obtain a series of standard absorption curves corresponding to the energy stages of the series of standard energy accelerators; and a computation unit for executing comparison of the absorption curves with the standard absorption curves so as to determine the energy the accelerator to be detected.

Description

technical field [0001] The invention relates to the field of energy and energy spectrum characteristic measurement of an accelerator X-ray source. More specifically, the present invention relates to a system for measuring the energy of accelerator X-rays. The invention adopts the principle of the transmission method, and uses the multi-layer detector group one-time exposure method to obtain the absorption curve of the accelerator dose in the group of detectors, supplemented by search and comparison of the standard energy accelerator dose absorption curve, and quickly and correctly determine the accelerator energy. Background technique [0002] Accelerator X-ray source is accelerated electrons to high energy by microwave acceleration tube or electrostatic acceleration tube. When electrons bombard the target material, due to bremsstrahlung radiation, a large number of X-rays appear symmetrically with the direction of electron movement. Average energy, energy spectrum, angular...
