A calibration neutron monitor for long-term cosmic ray modulation studies
(North-West University, 2006)The propagation of high-energy cosmic rays is influenced by the time-varying heliospheric magnetic field embedded in the solar wind, and by the geomagnetic field. To penetrate through this geomagnetic field, they must ... -
A GPS-based method for pressure corrections to neutron monitor data
(North-West University, 2008)Galactic cosmic rays are high-energy particles in the heliosphere. When entering the atmosphere of earth, they interact with the nuclei of air molecules, which then cascade down to the earth's surface. The nuclear active ... -
Synthesis and evaluation of a charge sensitive amplifier for neutron counters
(2013)Cosmic-ray fluctuations are monitored by neutron monitors using several different kinds of proportional counter tubes. An important component of these monitors is the electronic subsystem that registers and counts output ... -
Synthesis and evaluation of a monitoring and control system for a neutron monitor
(2014)Neutron monitors detect secondary particles produced by the collision of cosmic rays and atmospheric nuclei. The need exists for a mini-neutron monitor data acquisition system (MNM-DAS) to replace the existing recording ... -
Synthesis and evaluation of an autonomous neutron monitor system for use in a very low temperature environment
(North-West University (South Africa) , Potchefstroom Campus, 2016)The long standing study field of cosmic rays has been around since 1932 and as such, so has neutron monitors used to observe these high energy particles. One of the determining factors influencing the measurement of particles ...
