Embodiment

[0026] Such as Figure 1-Figure 5 As shown, a time-resolved fast-response X-ray detector includes a housing 1, a cathode, an anode 3, a coaxial output window 6, and a high-voltage input connector 7. The anode 3 is cylindrical, and its bottom is smoothly chamfered. In a dense mesh structure, a high-pressure resistant membrane 2 is attached to the outer side wall of the high-pressure resistant membrane 2 and a casing 5 is sheathed on the high-pressure resistant membrane 2, and a capacitor structure is formed by the anode 3, the high-pressure resistant membrane 2 and the casing 5. A coaxial connector 4 is fixed at the bottom of the housing 1, the cathode is formed by the inner conductor 41 of the coaxial connector, and the coaxial output window 6 is connected to the coaxial connector 4. Inwardly from the input window of the housing 1 are the anode 3, the coaxial connector 4, and the coaxial output window 6, and the bottom of the anode 3 is close to the inner conductor 41 of the co...

Abstract

The invention discloses a time resolution fast response X ray detector, comprising a shell, a cathode, an anode, a coaxial output window and a high-voltage input connector. The anode is barrel-shaped, the bottom of the anode is of a smoothly beveled dense sieve pore structure, and a high-voltage resistant film is pasted on the external sidewall of the anode; the high-voltage resistant film is externally sleeved with the shell; and the anode, the high-voltage resistant film and the shell form a capacitance structure. The detector provided by the invention has the characteristics of fast time response, high-voltage resistance, small volume and steady work.

Description

Technical field [0001] The invention belongs to the field of X-ray detectors, and in particular relates to a time-resolved fast-response X-ray detector. Background technique [0002] The X-ray pulse signal generated in the study of laser nuclear fusion carries a lot of information, and its pulse width is very narrow. In order to clarify the time change process of the X-ray pulse signal, a fast response X-ray detector is required. Furthermore, due to the complex spatial energy distribution of the generated X-ray signal and the limited space left by the host device for the detection area, in order to improve the accuracy of the spatial energy spectrum distribution of X-ray detection, a smaller and fast-response X-ray detector is required. [0003] There are many types of common X-ray detectors, including gas detectors, scintillator detectors and photoconductive detectors. The sensitivity of the gas detector is very low and the time response is very long, the shortest can only be in...
