Positron liquid perfusion system and method

Abstract

The invention discloses a positron liquid perfusion system and method. The positron liquid perfusion system comprises a part to be detected and a positron liquid perfusion pipeline system. The perfusion system is based on the perfusion system and includes: conducting liquid filling on the part to be detected according to specific needs of the part to be detected; and placing the part to be detected in a gamma photon detecting and imaging device and conducting the static or real-time three-dimensional imaging on the perfusion inner cavity structure. The positron liquid perfusion system and method is based on the positron annihilation principle, and can conduct the three-dimensional imaging on the complicated inner cavity structure of part and the inner wall micro-defects through the nuclide probe in the positron liquid.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a testing method for performing three-dimensional imaging of complex inner cavity structures of parts through positron liquid perfusion. Background technique [0002] As early as 1928, British physicist Dirac P A M predicted that electrons have anti-electrons when studying the quantum theory of electrons. In 1932, American physicist Anderson CD discovered the existence of positrons in the cloud chamber photos of cosmic rays, marking the existence of human beings. Start working on positrons. Later, people noticed that the gamma photons generated after the annihilation of positrons can obtain information such as electronic structures, defects and phase transitions inside metal materials, semiconductor materials, non-metal materials, and condensed matter, which has attracted the attention of scientists and scholars around the world. , is also the reason for the rapi...
