The invention discloses an X-ray time evolution process measuring device, and relates to the field of X-ray radiation flow quantitative measurement. The X-ray time evolution process measuring device comprises an X-ray time evolution process measuring device and an X-ray time evolution process measuring device, wherein the pulse broadening system comprises an acceleration region, a drift region anda collection region, the acceleration region is used for accelerating electrons and enabling the speeds of the electrons entering the acceleration region at different time periods to be different, the drift region is used for enabling the electrons to move at a constant speed, and the collection region is used for collecting the electrons; and the signal processing system is connected with the collection area and is used for obtaining a signal measurement result through broadening and back-stepping calculation. The X-ray time evolution process measuring device can broaden a signal, and then ameasuring result of a short pulse signal is obtained through broaden back-stepping calculation, so high-time-resolution measurement is realized.
Description
technical field [0001] The invention relates to the field of quantitative measurement of X-ray radiation flow, in particular to an X-ray time evolution process measurement device. Background technique [0002] In inertial confinement laser fusion research, X-ray radiation flow diagnostics are currently measured using two complementary techniques. [0003] One technique is to use a soft X-ray spectrometer composed of an X-ray diode (XRD) array to measure X-ray radiation flux and radiation energy spectrum. At present, a time-resolved energy spectrum with a resolution of 100 ps can be obtained through the energy channel response. [0004] Another technique is to use a flat response detector composed of a flat response film and a gold cathode XRD. This detector is also measured based on an XRD detector, and its time resolution is consistent with that of a soft X-ray spectrometer composed of an XRD array. Although this technology and device can realize quantitative measurement ...
