Abstract

The paper presents a research of the different components variations of the secondary cosmic rays (SCR). These are being monitored at the Cosmic Rays Laboratory, PGI, Apatity, using an integrated set based on the SCR basic components detectors. Also, besides stationary equipment, a mobile complex has been developed and made, which consists of a scintillation spectrometer, a charged component detector (CCD) based on the Geiger-Muller counters, and a neutron component detector (Е > 1 MeV) based on helium counters SNM-18. The mobile complex was put into operation in the early 2019. It operates in parallel with the basic equipment, recording SCRs. Small dimensions, effective energy consumption and ability to record data onto flash drives allows this complex to be used in SCR-monitoring in remote places, as well as on ships away at sea.

Highlights

When high-energy particles of the primary cosmic radiation pass through the Earth’s atmosphere, there appears a cascade of particles various in type and different in energy [1].The particles flux forms a secondary cosmic radiation (SCR) which is recorded at Polar Geophysical Institute (PGI), Apatity, with an integrated monitoring system developed and made at PGI
Due to the geometric parameters, simplicity of the set and their ability to operate in a self-contained regime, the detectors were integrated into a mobile complex to record several SCR components
The secondary particles fluxes consisting of the SCR electromagnetic, hadronic and charged components are recorded by detectors of different types: a neutron monitor (NM)

Summary

Introduction

When high-energy particles of the primary cosmic radiation pass through the Earth’s atmosphere, there appears a cascade of particles various in type and different in energy [1]. The particles flux forms a secondary cosmic radiation (SCR) which is recorded at Polar Geophysical Institute (PGI), Apatity, with an integrated monitoring system developed and made at PGI. The complex consists of detectors recording different SCR components, which allows accumulating an extensive database. Based on the detectors available and on specified tasks, mobile recording devices have been made. Due to the geometric parameters, simplicity of the set and their ability to operate in a self-contained regime, the detectors were integrated into a mobile complex to record several SCR components. The complex integrates a scintillation spectrometer, a charged component detector (CCD) based on the Geiger-Muller counters, and a neutron component detector (Е < 1 MeV) based on helium counters SNM-18
