| Abstract |
Cosmic Ray Neutron Sensing (CRNS) is a ground-based
technique that utilizes epithermal neutron measurements as a proxy for
environmental hydrogen content. Similarly to other ground-based cosmic
ray detectors (e.g., neutron monitors), CRNS detectors are affected by
the solar cycle and space weather events. Typically, these effects must
be corrected, but CRNS detectors have also been specifically used to
observe space weather. The specific sensitivity of CRNS detectors to the
primary spectrum and the relationship to other cosmic ray measurements
is not fully understood. A latitude survey was undertaken during the
maximum of solar cycle 25, utilizing a mini neutron monitor, two CRNS
detectors of different design and a muon telescope onboard the German
Research Vessel Polarstern. The observations are presented and used to
derive differential response functions and yield functions for two
neutron detectors. While the differential response, between neutron
detectors is similar, it strongly deviates between muon and neutron
detectors. |
