MEPhI: Neutron Analyzer

2024: Product Announcement

In August 2024, the world's first neutron analyzer was presented in Russia, capable of determining the composition of rocks. The development belongs to the National Research Nuclear University MEPhI. This device opens up new opportunities for the mining, oil and metallurgical industries, as well as for scientific research, allowing rapid and accurate analysis of the chemical composition of samples.

The analyzer works on the basis of the neutron radiation method, which uses irradiation of samples with fast neutrons. The device is able to penetrate deep into the sample and conduct non-destructive elemental analysis throughout its volume. The analysis time is only 30 minutes, which is much faster than existing analogues. A feature of the device is the ability to determine even light elements, such as hydrogen, boron and chlorine, which makes it especially in demand in various industries.

According to the developers, the neutron analyzer is based on measuring the spectra of gamma radiation, which occurs when neutrons interact with the nuclei of atoms in rocks. When irradiated with fast neutrons, inelastic scattering occurs, and the nuclei begin to emit gamma quanta. The radiation spectrum is unique for each chemical element, which makes it possible to determine their concentration in the sample with high accuracy. Additionally, the instrument uses thermal neutrons to analyze elements that are difficult to detect using other methods.

Oleg Chakilev, engineer of the Department of Applied Nuclear Physics, NRNU MEPhI, noted that the device can be used at various stages of mining - from exploration to control of the content of elements in ore. This is particularly important for the separation of ore into enriched and depleted ore. In addition, the analyzer can be used to analyze cuttings - rock leaving the well during drilling, which helps to determine the location of oil or gas deposits.^[1]
