“…Furthermore, the cryogenic equipment without liquid helium and liquid nitrogen adopted in large neutron facilities, such as cryostats, superconducting magnets, and other cryogenic systems have been reviewed clearly [18]. A specific neutron scattering measurement for researching internal stresses in engineering materials at the lowest temperatures of 30 K has been established, but the related diffraction angle and temperature accuracy were missing [19].…”

Internal stresses play a crucial part in determining a material's properties, which emphasizes the significance of accurate stress measurement and analysis. Neutron diffraction technology is a very promising approach to studying the complex microstructural properties of many materials, especially with the growing demand for cryogenic studies. This new device has a robust load capacity of 50 kN and works smoothly in a wide temperature range of 6 K to 473 K. Furthermore, the diffraction angle is 47 degrees broader. Regardless of the samples, we observed that a thermal balance point existed close to 180 K. Importantly, thermal resistance (TR) was eliminated by the use of an analytical method, which has an extraordinarily small error of 2%. Using this exact calibration methodology ensures that the sample temperature is accurate during the experiments. This work presents a crucial apparatus for investigating the complexity of internal stresses in materials and offers an effective method for estimating and managing sample temperatures while doing research.
