On the relationship of cosmic ray flux and precipitation [PDF]

open access: yes, 2001
This paper evaluates whether there is empirical evidence to support the hypothesis that solar variability is linked to the Earth's climate through the modulation of atmospheric precipitation processes.

Cosmic ray proton spectrum determined with the imaging atmospheric Cherenkov technique

open access: yesPhysical Review D, 1999
The HEGRA system of 4 Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to determine the flux and the spectrum of cosmic ray protons over a limited energy range around 1.5 TeV. Although the IACT system is designed for the detection of gamma-rays with energies above 500 GeV, it has also a large detection area of $ \simeq 10^6 m^2 \cdot 3 ...

The 22-Year Hale Cycle in Cosmic Ray Flux – Evidence for Direct Heliospheric Modulation [PDF]

open access: yes, 2014
The ability to predict times of greater galactic cosmic ray (GCR) fluxes is important for reducing the hazards caused by these particles to satellite communications, aviation, or astronauts.

Low Background Radiation Detection Techniques and Mitigation of Radioactive Backgrounds

open access: yesFrontiers in Physics, 2020
The study of rare fundamental physics phenomena, such as double-beta decay, rare nuclear decays and dark matter, requires very low levels of background radiation in order to observe a signal.

A new numerical technique to determine primary cosmic ray composition in the ankle region [PDF]

open access: yesAstroparticle Physics, 2009
In this paper we introduce a new multiparametric technique that attempts to tackle simultaneously the problems of composition determination and hadronic interaction uncertainty. Employing simulations of a real world detector under its planned operational conditions, and disregarding systematics, we can asses that the present technique should be able to

A simple technique for gamma ray and cosmic ray spectroscopy using plastic scintillator

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2016
A new and simple technique has been developed using plastic scintillator detectors for gamma ray and cosmic ray spectroscopy without single channel analyzer (SCA) or multichannel analyzer (MCA). In these experiments only a leading edge discriminator (LED) and NIM scalers have been used.
