Abstract

The invention provides a mesh electrode diamond X-ray measuring device. The end face of diamond in the measuring device is plated with a mesh electrode and a circular electrode. A connecting ring is fixedly connected to the front end of a shell through a thread in a sleeving mode. A gasket, the diamond, an insulation ring and an insulation layer are sequentially arranged on the central axis in the shell. The gasket, the diamond and the insulation ring are pressed in the shell through the connecting ring. The gasket is connected with the mesh electrode in a pressed mode. The insulation layer is fixedly connected with the shell. A core pin is wrapped in the insulation layer and penetrates through the insulation ring to be connected with the circular electrode. A joint externally connected with a cable is arranged at the tail end of the shell. Through the mesh electrode diamond X-ray measuring device, attenuation of X-rays is reduced, it is guaranteed that the low-energy X-rays can directly irradiate the diamond, and X-ray radiation measurement in the inertial confinement fusion field is realized. A concentric structure is more beneficial for realizing impedance matching of detectors, and measurement signal distortion is reduced. The large-area mesh electrode is more beneficial for sensitivity calibration and measurement application.

Description

technical field [0001] The invention belongs to the field of X-ray radiation measurement, in particular to a mesh electrode diamond X-ray measurement device. Background technique [0002] Most current detection of radiation relies on silicon photodiodes or PIN diodes. The downside of silicon photodiodes is that they respond to visible light and are susceptible to damage from neutron radiation. Another commonly used soft X-ray detector is the vacuum X-ray diode, but the sensitivity of the X-ray diode is very low and varies with the photon energy. Therefore, it is necessary to seek an X-ray detector that does not respond to visible light and responds flatly within the spectrum range. Inertial confinement fusion ignition experiments require detectors to respond quickly, have high sensitivity, and have a certain ability to resist radiation damage. Both natural single crystal and polycrystalline diamond can be used for a variety of radiation detection, including X-ray, gamma r...
