Problems solved by technology

[0004] In short, this kind of sample console requires multiple functions, and has the characteristics of insulation, heat conduction, and non-magnetism. In addition, the limitation of ultra-high vacuum on the use of materials makes its design difficult.
At present, the commercial equipment on the market is expensive, and there is no special non-magnetic design, and the functions do not match, so it needs to be designed separately to meet the needs of XMCD experiments.

Abstract

The invention provides a low-temperature sample operation bench used for soft X-ray magnetic circular dichroism (MCD). The operation bench includes: a wiring chamber having an upper end and a lower end; an X-Y-Z three-dimension moving bench mounted on a XMCD ultrahigh-vacuum chamber, the lower end of the wiring chamber mounted on the X-Y-Z three-dimension moving bench; a liquid nitrogen cooling apparatus connected to the upper end of the wiring chamber and passing through the X-Y-Z three-dimension moving bench; a copper cold head fixed on the lower end of the liquid nitrogen cooling apparatus; and a sample bracket being installed on the lower end of the copper cold head and being insulated from the copper cold head. The liquid nitrogen cooling apparatus is filled with liquid nitrogen so as to cool the sample on the sample bench. The low-temperature sample operation bench used for soft X-ray MCD achieves liquid nitrogen low temperature refrigeration as most as possible on the basis of consideration of insulation, magnet-free and high vacuum degree.

Description

technical field [0001] The invention relates to a low-temperature sample operating platform, in particular to a sample operating platform for measuring soft X-ray magnetic circular dichroism absorption spectrum under the conditions of ultra-high vacuum, strong magnetic field and low temperature. Background technique [0002] The soft X-ray magnetic circular dichroism (XMCD) experimental technique is a powerful tool for the characterization of magnetic materials, and has extensive and important applications in condensed matter physics, magnetism, and material science. This experimental technology has strict requirements on the sample environment, and needs to take into account experimental conditions such as ultra-high vacuum, strong magnetic field, and low temperature. At present, there is a lack of perfect XMCD experimental equipment in China, and there is even a lack of low-temperature sample consoles suitable for such experimental conditions. [0003] Since the sample man...
