Structure for realizing ultra-high temperature heating of synchrotron radiation light source in-situ tensile CT imaging experiment

Abstract

The invention provides a structure for realizing ultra-high temperature heating of a synchrotron radiation light source in-situ tensile CT imaging experiment. The structure comprises an electron gun,a vacuum chamber and a vacuum unit communicated with the vacuum chamber. An in-situ stretching table is arranged in the vacuum chamber, the electron gun is arranged above the side wall of the vacuum chamber and communicated with the vacuum chamber, and electron beams emitted by the electron gun can bombard a sample on the in-situ stretching table. Heaters are arranged on the two sides of the sample on the in-situ stretching table, and a heat insulation structure is arranged between the rotating shaft of the in-situ stretching table and the clamp. The in-situ stretching table rotating shaft iscoated with a cooling device. The structure can heat the sample to room temperature to 1800 DEG C, and ensure that the in-situ stretching device and other precision parts are in a room temperature state.

Description

technical field [0001] The invention relates to heating technology, in particular to a structure for realizing ultra-high temperature heating in in situ stretching CT imaging experiments of synchrotron radiation light sources. Background technique [0002] Synchrotron radiation light source is one of the large scientific devices that the world's scientific and technological powers attach great importance to. Synchrotron radiation light has the advantages of high brightness, high coherence, and high penetrating ability, and has become a powerful probe for detecting the microstructure of matter and its evolution law. CT imaging is an important application of synchrotron radiation. This technology can non-destructively analyze the different microstructures inside materials, and has important applications in archaeology, geology, materials and other fields. When it is necessary to use synchrotron radiation CT imaging technology to study the microstructure evolution of matter in ...
