Abstract

The invention discloses a measurement device for accelerator ray bundles. The measurement device for the accelerator ray bundles comprises an attenuation body device, a detector and a position adjusting device. The attenuation body device is provided with a working part, the working part resists ray bundles from an accelerator target spot and reduces strength of the ray bundles, the detector is used for detecting strength or dosage of the ray bundles which penetrate through the working part of the attenuation body device and the position adjusting device is used for carrying the attenuation body device and the detector and adjusting spatial positions of the attenuation body device and the detector. The thickness of the working part of the attenuation body device is variable, and therefore different attenuation to the strength of the ray bundles is conducted. The attenuation body device with the working part of which the thickness is variable and the position adjusting device for carrying and positioning the attenuation body device and the detector are arranged on the measurement device, and therefore adjustment of the attenuation body device and positioning accuracy of the device are improved.

Description

technical field [0001] The invention relates to a precise measuring device for a ray beam, in particular to a measuring device for an accelerator ray beam. Background technique [0002] In the application field of nuclear technology, especially in the container safety inspection system, it is often necessary to measure the dose or dose rate, energy and half-value layer of the ray beam emitted by the electron accelerator. The ray beam emitted by the accelerator is invisible and divergent, such as fan-shaped, conical, rectangular, etc., and the attenuator, detector, attenuator and ray are required in the process of measuring the energy and half-value layer of the accelerator ray beam The mutual positional relationship between the beam targets has a great influence on the accuracy of the measurement results. If the placement is not in place or the mutual position changes during the test, large measurement errors will be introduced. However, in existing measurement methods, the...
