Description
Technical Field
The invention relates to the technical field of soft X-ray pulse calibration systems and peripheral matched equipment thereof, in particular to a monochromator for pulse type soft X-ray calibration.
Background
Detectors such as X-ray diodes (XRD) are important equipment for laser inertial confinement fusion quantitative experiments and are mainly used for obtaining key physical quantities such as black cavity radiation spectrums, radiation temperatures and the like. In the radiation-driven inertial confinement fusion research, the accurate measurement of the black cavity radiation soft X-ray spectrum depends on the accurate calibration and spectrum resolving algorithm of the energy spectrum response characteristic of a multi-channel XRD spectrometer. However, the current general light source for calibrating the XRD detector adopts a synchrotron radiation light source, and the calibration source has two natural defects: 1) the light time for synchrotron radiation is limited, and only one light window time is used in one year, so that whether the performance and the state of XRD change in a laser inertial confinement fusion experiment or after the experiment cannot be confirmed and verified in time; 2) the synchronous radiation light source is a continuous direct current light source, the experimental environment and the measurement object of XRD are generated by the action of super-strong laser and substances, and have extremely strong pulse (ns pulse) characteristics and large transient power of an X-ray source, namely, the XRD calibration source has large difference with the experimental measurement object. Based on the strong pulse generated by the action of the strong laser plasma, the calibration light source has the characteristics of high brightness, good stability and the like, the purpose that the XRD calibration condition is close to the measurement application condition is realized, and the XRD measurement precision can be improved.
In 2007, some scholars propose a high-power laser-based Shenguang II laser device, which uses two multilayer mirrors with basically consistent performance as a dispersion element to convert continuous X-rays generated by laser targeting into monochromatic light (4 channels) with the same energy, so as to obtain dual-channel strong-pulse soft X-ray monochromatic light, and further realize calibration of two XRD energy points. Except for the Shenguang II laser device, the strong pulse soft X-ray calibration system with double energy points is realized by using a filter and a multilayer mirror structure, and no other effective mode or method exists. Based on high power laser deity II laser device, two multilayer mirrors with basically consistent performance are used as dispersion elements, the problem of synchronous radiation direct current continuous calibration is solved, but the following defects still exist: 1) the calibration system only comprises double pairs of soft X-ray energy points, the range of the covered energy points is narrow, and the calibration application is limited; 2) the calibration system takes the multilayer mirror as a dispersion element, has low energy spectrum resolution (the energy spectrum resolution is less than 50), and has certain influence on the precise calibration of the detector, thereby influencing the uncertainty of an experimental result.
Therefore, how to change the current situation that the coverage energy point range is narrow and the energy spectrum resolution is low in the soft X-ray pulse calibration process in the prior art becomes a problem to be solved urgently by those skilled in the art.
