Abstract

The invention relates to a multi-mass-to-charge-ratio ion beam mass spectrometry device and method. The multi-mass-to-charge-ratio ion beam mass spectrometry device comprises an ion source, a focusingmodule, a magnetic separation module, an acquisition module and a data processing module. The ion source is used for emitting an ion beam comprising ions with multiple mass-to-charge ratios; the focusing module is used for focusing the ion beam; the magnetic separation module is used for separating ions with different mass-to-charge ratios in the focused ion beam along different curvature radiuses according to the magnetic stiffness; the acquisition module is arranged at the ion beam imaging end of the magnetic separation module and is used for receiving the ions with different mass-to-chargeratios corresponding to the curvature radiuses and generating corresponding electric signals; and the data processing module is connected with the acquisition module, and is used for determining thetypes and proportions of ions with different mass-to-charge ratios according to the curvature radius and the electric signals generated by the acquisition module. The device solves the problems that in the prior art, the device is long in distinguishing time, and the application range is narrow due to the fact that the sample component proportion distinguishing capacity is insufficient.

Description

technical field

[0001] The invention relates to a multi-mass-to-charge ratio ion beam mass spectrometry device and method, and belongs to the technical field of accelerators. Background technique

[0002] Accelerator-based mass spectroscopic analysis (accelerator-based mass spectroscopic analysis) refers to a nuclear analysis method that combines accelerator and mass spectrometry. The mass-to-charge ratio characteristics of the ion beam are separated to identify the ion type and proportion of the sample.

[0003] Accelerator mass spectrometry technology was produced in the 1970s. At the beginning of its development, it was mainly used for the rapid and accurate measurement of radioactive isotopes in earth science and archaeology. After more than half a century of development, accelerator mass spectrometry has been deeply used in many modern scientific and technological fields such as archaeology, biomedicine, geology, hydrology, cosmology, nuclear physics, etc., widely invo...
