Abstract

The invention provides a miniature time-resolved laser pumped X-ray detector. The miniature time-resolved laser pumped X-ray detector comprises: a miniature X-ray instrument arranged in the reflected light direction of a beam splitter and used for receiving a reflected beam emitted from the beam splitter and guiding the reflected beam to bump high-energy electron beam bunch in the instrument to generate ultra-short pulse X-rays; and a two-dimensional pixel array X-ray detector arranged behind a three-dimensional sample stage used for receiving diffraction pattern information generated after the detection ultra-short pulse X-rays passing through an excited sample, and analyzing, wherein the diffraction pattern information is analyzed and displayed by a computer electrically connected with the two-dimensional pixel array X-ray detector. Ultra-fast femtosecond laser and the detection X-rays have the natural time synchronization characteristic; and compared with existing devices of the same kind, the miniature time-resolved laser pumped X-ray detector has the advantages of compact structure, small size and low cost, can be used to build large hospitals and academic institutions, and is convenient to promote.

Description

technical field [0001] The invention belongs to the technical field of time-resolved pump detectors, in particular to a miniaturized time-resolved laser-pumped X-ray detector. Background technique [0002] In the fields of biology, chemistry, and new materials, it is necessary to detect the transient or ultrafast process of the change of the microstructure of matter, which is of great significance to the scientific understanding of the nature of matter. For example, the motion of atoms in single molecules, liquids or crystals, the breaking and forming of chemical bonds, the transfer of charges, the isomerization of molecules, etc. Using the pump-probe method established based on the femtosecond pulse laser with ultrashort pulse width to study the above ultrafast process is to apply a beam of ultrashort pulse laser to the material to stimulate a transient change process, after a certain time delay After a period of time, another beam of ultrashort pulse laser is used as a pr...
