Abstract: Promoting the development of deep-sea mineral exploration instrumentation can help alleviate the global resource shortage faced by mankind. X-ray fluorescence (XRF) spectrometry analysis has been widely used in the in-situ analysis of deep-sea minerals due to its fast analytical speed, non-destructive and wide analytical range. This paper focuses on the structural safety and detection efficiency of X-ray fluorescence in-situ measurement equipment under high pressure for deep-sea XRF analysis. The paper will first combine finite element analysis (FEA) and experimentation to design and optimize the structure of an X-ray probe tube required for deep-sea mineral exploration, determining the Be window thickness to ensure stress safety. Then, the Monte Carlo method was used to analyze and optimize the Be window thickness on the X-ray probe tube to improve the accuracy of the elemental analyses. Finally, the effect of the seawater thickness between the transmitter outer tube and the rock wall was also considered. The results show that based on the ocean depth in different detection environments, Be windows with a thickness of 1.5 mm or 2.0 mm can be selected to improve the detection efficiency of the device while ensuring the structural safety of the instrument. According to the design features and detection requirements of the device, in the deep-sea exploration of minerals with characteristic peak energy below 10 keV, the transmitter outer tube should be as close as possible to the rock wall inside the logging, and when the characteristic peak energy of the minerals is more than 10 keV, the distance between the transmitter outer tube and the rock wall inside the logging should be controlled to be about 2 mm. This study provides feasible solutions for future deep-sea mineral resource development, and a useful reference for elemental analysis of minerals in deep-sea or other extreme working environments.
