Scintillation muon telescope module with fiber-optic light collection

A scintillation muon telescope module with fiber-optic light collection using silicon photomultipliers was developed, tested, and installed for continuous monitoring to study cosmic ray variations. The aim of this study was to create a scintillation muon telescope module, continuously monitor the muon component in test mode, and study the long-term stability of the detector parameters. Methods for processing the obtained data were developed. To assess the stability of the module parameters, an internal control technique was used, involving data from other detectors. The results of testing and long-term continuous monitoring showed that the stability of the developed muon detector is better than 0.1%/year, without the need for its operation in a thermostatic chamber. The study concludes that ease of operation, cost, compactness, low power consumption and stability are factors that determine the advantages of the developed module, which is an essential element for constructing a multidirectional muon telescope.

Mobile neutron monitor for latitude cosmic ray monitoring

Neutron monitors are a standard tool for high-precision continuous monitoring of galactic cosmic ray flux variations arising from variations in heliospheric conditions and solar activity for space weather applications. These measurements form the basis for solving the inverse problem of determining the cosmic ray anisotropy vector beyond the magnetosphere. To support such studies, periodic latitude measurements are necessary to determine the coupling functions of primary and secondary cosmic rays variations. The aim of this work is to develop and characterize a modernized standard neutron monitor based on a CHM-15 boron thermal neutron counter and a data acquisition system designed for marine expeditionary studies of cosmic ray variations. Modern nuclear physics experimental methods and the principles of microprocessor-based data acquisition systems were used to solve this problem. The results of test trials and of continuous monitoring showed that the characteristics of the upgraded and standard neutron monitor are similar, and the ease of use, compactness, and stability allow us to conclude that the mobile neutron detector can be used in expeditionary conditions with limited access for maintenance personnel.

Approximation of the reception coefficients of cosmic rays neutron component for latitude measurement

When solving scientific and applied problems, such as latitude monitoring, it is important to correctly exclude primary cosmic ray variations from observation data. Therefore, the purpose of this study was to develop and implement a method for correcting monitoring data, the key point of which was to obtain reception coefficients as a function of latitude. This resulted in an approximation of the rigidity dependence of the zeroth and first harmonic cosmic rays anisotropy coefficients, calculated for a ground-based cosmic ray detectors network. Analysis of the obtained results showed that the approximation was performed with high accuracy, and the results are suitable for use in latitude measurements during marine expeditions.
