This paper describes the hardware and software of the probe, the core component of the new generation Xray fluorescence logging instrument. SiPIN semiconductor detector has been adopted in XRF logging probe and a structure fixing the excitation source on both sides of the detector has been designed. In this system, the ARM7 microprocessor is used as a control core, and RS485 is employed as communication protocol, with the maximum measurable depth being 2 000 meters below the ground. This system was tentatively applied in the Lala copper mine of Huili County, Sichuan Province, and the results show that the Xray fluorescence logging instrument can obtain the content of elements in various ores within rocks and sidewalls rapidly. Hence this system provides an effective analytical method for exploring deeper resources.
