Category 1: Peer-reviewed literature

Observations of temporary Forbush decreases (FDs) in the Galactic cosmic-ray (GCR) flux due to the passage of solar storms are useful for space-weather studies and alerts. Here…

Monte Carlo Simulation of the Neutron Monitor and Position-Dependent Bare Neutron Counter Yield Functions at Mawson Station, Antarctica 38th International Cosmic Ray Conference, 2024 (Ref: 17183)
Authors:
Madlee S.Ruffolo D.Sáiz A.Muangha P.Nuntiyakul W.Seripienlert A.Mangeard P.S.Duldig M.L.Humble J.
Category 3: Conference paper

Neutron monitors (NMs) are ground-based detectors that are widely used to detect secondary particles produced by the collisions of primary cosmic rays (CRs) and air molecules in the Earth's atmosphere. Bare neutron counters (BCs), operated without the lead producer and polyethylene reflector…

Cross-counter time-delay distributions at the Mawson neutron monitor Proceedings of 38th International Cosmic Ray Conference, 2024 (Ref: 17184)
Authors:
Sáiz A.Ruffolo D.Sukha T.Muangha P.Mitthumsiri W.Chaiwongkhot K.Nuntiyakul W.Somboon E.Evenson P.Duldig M.Humble J.
Category 3: Conference paper

For decades, neutron monitors have been the primary source of ground-level data for studying cosmic rays with rigidities slightly above the geomagnetic cutoff. The NM64 instrument design, the standard for neutron monitors, has been optimized to monitor neutrons produced in atmospheric cascades.
