Abstract

The invention discloses a high-temporal-spatial-resolution soft X-ray radiation flow quantitative measuring system. According to the system, a measured light source is arranged in front of two grazingincidence X-ray microscopes, X-rays emitted by the light source respectively pass through two channels of the microscopes and are respectively imaged to an X-ray diode detector and a cathode of an X-ray streak camera through a slotted scintillator, a neutral attenuator and a composite filter, photoelectrons are generated, and high-temporal-spatial-resolution measurement of the X-ray radiation flow can be realized. Compared with the prior art, according to the system, pinholes are replaced by the grazing incidence X-ray microscopes for imaging, the spatial resolution and the sensitivity of themeasuring system are improved, the streak camera and the X-ray diode detector perform comparative measurement, quantitative measurement of the X-ray radiation flow is realized by the streak camera, and the temporal resolution of the measurement of the radiation flow is improved; besides, high-temporal-spatial resolution quantitative measurement can be performed on the energy flow of the nanosecond pulse soft X-ray source radiation, and the application prospect of the system in the field of pulse X-ray radiation detection is wide.

Description

technical field [0001] The invention belongs to the field of pulsed X-ray detection, and in particular relates to a quantitative measurement system for soft X-ray radiation flow with high temporal and spatial resolution. Background technique [0002] In the prior art, pinhole imaging is adopted, and a diaphragm with a diameter of 2 mm is placed on the image plane, so that the X-rays emitted by a specific area of ​​the light source pass through, and the X-rays emitted from the small hole of the diaphragm are detected by a flat-response X-ray diode detector The measurement can realize area-resolved X-ray radiation flow quantitative measurement (a space-resolved radiation flow detection device CN 105158789 B and a local area soft X-ray radiation flow quantitative measurement device and measurement method CN 105204059 B). [0003] In the above technology, a pinhole with a diameter of 80-100 μm is used to image the X-ray radiation of the light source. The spatial resolution is eq...
