Neutron and X-ray double-spectrum imaging camera

Abstract

The invention discloses a neutron and X-ray double-spectrum imaging camera. The neutron and X-ray double-spectrum imaging camera comprises a flight pipe, the flight pipe comprises a main part, and a first branch part and a second branch part communicated with the main part, wherein the main part and the second branch part are coaxially arranged, and axis of the first branch part and the axis of the second branch part have an included angle; a composite imaging assembly, a first optical image sensor and a second optical image sensor are respectively arranged at outside of the main part, the first branch part and the second branch part, an optical element, a X-ray scintillator and a neutron scintillator are arranged in the flight pipe, wherein the X-ray scintillator is positioned at a frontpart of the optical element, and the neutron scintillator is positioned at a rear part of the optical element. By employing the above structure, two spectrum segment images of neutron radiation and X-ray radiation emitted by a certain radiation source direction can be recorded, an X-ray signal and a neutron radiation signal are separated in a reasonable mode, and a signal to noise ratio of the images is high.

Description

technical field [0001] The invention belongs to the technical field of radiation detection, in particular to a neutron and X-ray dual-spectrum imaging camera. Background technique [0002] Radiation sources produced in fusion or fission reactions emit two types of radiation, X-ray radiation and neutron radiation, two types of ionizing radiation originating from physical reactions at different stages inside the radiation source. Recording the radiation images of different spectral bands of the radiation source from the same angle can provide information on the spatial distribution of different reaction processes or material states in the radiation source, and help people accurately grasp the physical state of the radiation source. [0003] However, due to the different penetration capabilities of different ionizing radiations, the imaging elements and radiation detection materials used are also different. Due to the strong penetrating power of neutron radiation, the penumbra...

AI Technical Summary

Problems solved by technology

If two different recording devices are used to perform neutron radiation imaging and X-ray radiation imaging on the radiation source, the recorded images will not be comparable in space due to the different viewing angles of the recording devices, and it will not be possible to provide accurate information inside the radiation source. The spatial information of , it is urgent to solve the above problems
