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] like image 3 , 4 As shown, the present invention provides a multi-channel KB microscope structure with quasi-coaxial observation function, the structure is composed of 2n pieces of KB mirrors 1 to 2n arranged in the same direction, and the mirrors are in the meridional direction and the sagittal direction. They are sequentially combined to form a plurality of independent imaging channels, namely, 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 arranged in the same direction, and for the KB mirror 1' to mirror n' in the sagittal direction, the working reflection surfaces are also in the same direction. to arrange.

[0027] The KB mirrors arranged in the same direction have slight differences in the spatial attitude. After the X-rays emitted by the object point pass through them, image points with a certain spatial ...

Abstract

The invention relates to a multi-channel KB microscope structure with quasi-coaxial observation function. The structure includes a plurality of mirror groups arranged in sequence along the optical axis direction, and each mirror group is respectively composed of a first mirror group arranged along the meridional direction. The reflection mirror is composed of a second reflection mirror arranged along the sagittal direction, so as to form multiple independent imaging channels. Compared with the prior art, the present invention has the advantages of strong coaxiality, reduced viewing angle difference, independent imaging, and consideration of different X-ray energy requirements. The invention is especially aimed at the research of inertial confinement fusion (ICF), realizes the reflection of X-rays in a relatively large energy span, can effectively improve the observation accuracy of ICF physical experiments, and solves the difficulties related to fusion ignition at home and abroad.

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 infer the temperature and density of the hot spot plasma by observing the signal intensity of the hot spot plasma in different energy X-ray energy segments in the later stage of ignition, which is the focus and difficulty of the current research on fusion ignition at home and abroad. The region of interest for the observation of hot spots has spatial features of small size (about several hundred 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 radiati...
