Problems solved by technology

In order to ensure the inversion accuracy of hot spot temperature and density, X-ray energy is required to have a certain distinction, which has insurmountable difficulties in the preparation of multi-layer films with multi-channel KB structures that share mirrors. Therefore, multi-channel KB microscopes are currently common Only work for a single energy or energy segment

Embodiment

[0025] Such as image 3 , 4 As shown, the present invention provides a multi-channel KB microscope structure with a quasi-coaxial observation function, which is composed of 2n blocks of KB mirrors 1 to 2n arranged in the same direction, and the mirrors are arranged in the meridian direction and the sagittal direction They are sequentially combined to form a plurality of independent imaging channels respectively, that is, mirrors 1 and 1' form image 1, mirrors 2 and 2' form image 2, ..., mirrors n and n' form image n.

[0026] For the KB mirror 1 to mirror n in the meridional direction, the working reflection surfaces are all arranged in the same direction, and for the KB mirror 1' to mirror n' in the sagittal direction, the working reflection surfaces are also arranged in the same direction. to arrange.

[0027] The KB mirrors arranged in the same direction have slight differences in their spatial attitudes. After the X-rays emitted by the object point pass through them, ima...

Abstract

The invention relates to a multichannel KB microscope structure with a quasi-coaxial observation function. The structure comprises a plurality of reflecting mirror sets which are sequentially arrangedin the optical axis direction, wherein each reflecting mirror set is composed of a first reflecting mirror arranged in the meridian direction and a second reflecting mirror arranged in the sagittal direction, so that a plurality of independent imaging channels are formed. Compared with the prior art, the structure of the invention has the advantages of high coaxiality, reduction of observation visual angle difference, independent imaging, consideration of different X-ray energy requirements and the like. According to the invention, X-ray reflection is realized in a large energy span especially for the research of ICF (Inertial Constraint Fusion), so that the observation precision of ICF physical experiments can be effectively improved, and the difficulties of fusion ignition related research at home and abroad are solved.

Description

technical field [0001] The invention relates to the field of laser inertial confinement fusion observation, in particular to a multi-channel KB microscope structure with quasi-coaxial observation function. Background technique [0002] X-ray imaging is an important diagnostic tool for high energy density physics (HEDP) and inertial confinement fusion (ICF) research. Its core is to inversely deduce the temperature and density of hot spot plasma by observing the signal intensity of hot spot plasma at different energy X-ray energy ranges in the late stage of ignition, which is the focus and difficulty of fusion ignition related research at home and abroad. The region of interest for observing hot spots has spatial features of small size (about hundreds of microns), so the KB (Kirkpatrick-Baez) microscope with high spatial resolution of 3-5 μm is the key equipment for such diagnostic observations. At the same time, the spatial information of hot spot radiation also has signific...
