Abstract
The invention relates to a mineral age tester with a background compensation function, which is particularly applied to the age testing of geological mineral samples. The mineral age tester comprises a detector and a host machine which are connected with each other by a control line, wherein the detector comprises a test darkroom and a background darkroom which are called as a darkroom collectively and are integrally connected side by side and a test photomultiplier and a background compensation photomultiplier which are respectively arranged on the test darkroom and the background darkroom; the shapes and structures of the test darkroom and the background darkroom are identical; positions of added sample wafers relative to the test photomultiplier and the background photomultiplier are the same, and the types of the test photomultiplier and the background compensation photomultiplier are the same; the types and specifications of detecting optical filters arranged in front of the two photomultipliers are the same; the darkroom has a dual-layer shell structure, namely a shell is wrapped outside a darkroom base; and sealing structures are arranged at each interface of the detector. The mineral age tester has the advantages of small volume, light weight, high sealability and sensitivity, dynamic compensation and the like, and is convenient to operate.
Description
technical field [0001] The invention relates to a mineral age measuring instrument with background compensation function which is specifically applied to the age determination of geological mineral samples. Background technique [0002] Solid mineral crystals grow in the natural environment, and the congenital defects generated during the growth process and the radiation from the acquired environment will cause lattice defects inside the crystal, forming free energy storage electrons. These energy storage electrons stored in the crystal will emit photons when stimulated by external energy. The method of using light energy to excite mineral crystals is called optical luminescence. Optical luminescence is a kind of phosphorescence. Under a fixed light source and the same excitation conditions, the total amount of photons of this phosphorescence is proportional to the total amount of energy-storing electrons in a solid. This is the theoretical basis for the application of opti...
