Problems solved by technology

However, the structure it adopts is a more general OSL dating instrument structure, and it is only suitable for the radiation dose detection of food.
[0006] At present, the dating of mineral samples requires the measuring instrument to be small in size, light in weight, and easy to carry, etc., but the existing dating instruments cannot meet the requirements

Embodiment Construction

[0037] Such as figure 1 As shown, an embodiment of the present invention is a portable mineral dating instrument, which determines the age of the mineral by measuring the radiation dose received during the long burial period. This embodiment includes two main parts: the detector composed of the darkroom 1 and the photomultiplier tube 2 and the host 5; the photomultiplier tube 2 and the host 5 in the detector are connected by a control line (1) 3, and the host 5 is connected to the photoelectric The control signal of the multiplier tube 2 and the electric pulse converted by the photomultiplier tube 2 are transmitted by the control line (1) 3; the darkroom 1 and the host 5 are connected through the control line (2) 4, and the host 5 switches the excitation light source 9 The control signal is transmitted through the control line (2) 4.

[0038] Such as figure 2 As shown, the darkroom 1 of this embodiment includes a darkroom housing 8, a darkroom upper cover 6, a darkroom base 13, ...

Abstract

The invention relates to a portable mineral age determinator specifically applied to age determination of geological mineral samples. The age determinator includes a detection machine and a host machine that are connected through a control line. The darkroom comprises a darkroom housing, a top cover of the darkroom, a darkroom base plate, a photomultiplier fixed on the top cover of the darkroom, an optical filter for detection fixed in front of the photomultiplier, an excitation light source installed on the darkroom base plate and controlled by the host machine, an excitation optical filter fixed in front of the excitation light source, and a detachable box type sample wafer holder positioned at the center of the darkroom base plate. The host machine comprises an ARM (Advanced RISC Machines) machine, a liquid crystal screen, a high pressure control module, a high pressure module, a pulse shaping module, a counting module and a light source control module. The darkroom is configured with a double-housing structure, in other words, another housing exists outside the darkroom. And each interface of the detection machine is provided with a sealed structure. The present invention has the advantages of small volume, light weight and portability.

Description

Technical field [0001] The invention relates to a portable mineral dating instrument specifically applied to the dating of geological mineral samples. Background technique [0002] The geological age refers to the time when various geological events occurred on the earth. It has two meanings: one refers to the sequence of occurrence of geomorphic events, called the relative geological age; the other refers to the age since the occurrence of geomorphic events, which is called isotopic geological age due to the use of isotopic techniques ( Absolute geological age). The combination of these two aspects constitutes a complete understanding of geological events and the evolution of the earth and crust. [0003] In view of the inherent characteristics of solid mineral crystals, it grows in the natural environment, the defects generated in the process of crystal formation and the radiation brought to it by the acquired environment will cause the lattice defects inside the crystal to for...
