Abstract

The invention discloses a microbeam proton fluorescence spectrometer, which comprises a proton accelerator (4), a proton convergence component and a detector (6), wherein the proton accelerator (4) is used for emitting protons, the proton convergence component is used for converging protons emitted by the proton accelerator (4), and the detector (6) is used for receiving the fluorescence excited from the protons; the proton convergence component is a capillary optical converger (1); and the capillary optical converger (1) at least comprises a single capillary (2). The fluorescence spectrometer converges protons by using the capillary optical converger (1); and the capillary optical converger (1) is made of glass capillaries, and does not need to be supported by a bracket. Thus, the invention has the advantages of simple structure and low cost, thereby realizing proton convergence in a simple, economical and practical way. In addition, the invention simplifies the structure of the fluorescence spectrometer and lowers the production and use cost of the fluorescence spectrometer.

Description

technical field [0001] The invention relates to the technical field of proton fluorescence analysis, in particular to a micro-beam proton fluorescence spectrometer for performing micro-area proton fluorescence analysis on samples. Background technique [0002] Proton fluorescence technology uses proton beams to excite the characteristic X-rays of atoms in the sample, and then analyzes the characteristic X-rays to obtain information such as the elemental composition of the sample. Due to the low detection limit of proton fluorescence technology, this technology has a wide range of applications. With the continuous improvement of people's requirements for sample analysis, micro-beam proton fluorescence technology has attracted much attention, because micro-beam proton fluorescence technology can perform two-dimensional proton fluorescence micro-area scanning analysis on samples. In the development of micro-beam proton fluorescence technology, how to make protons converge is th...
