Abstract

Launched from McMurdo (Antarctica) in December 2005, the balloon experiment CREAM (cosmic ray energetics and mass) collected about 15 million triggers during its second flight of 28 days. Redundant charge identification, by two pixelated silicon arrays and a time resolved pulse shaping technique from a scintillator system, allowed a clear signature of the primary nuclei. The energy was measured with a tungsten/SciFi calorimeter preceded by a graphite target. Preliminary results from the analysis of the data of the second flight are presented.

First measurements of periodicities and anisotropies of cosmic ray flux observed with a water-Cherenkov detector at the Marambio Antarctic base

Noelia Ayelen Santos, Sergio Dasso, Adriana Maria Gulisano, Omar Areso, Matias Pereira, Hernan Asorey, Lucas Rubinstein, LAGO collaboration

Summary: A new water-Cherenkov radiation detector at the Argentine Marambio Antarctic Base has been monitoring the variability of galactic cosmic ray flux since 2019. Its main purpose is to provide experimental data for studying the interplanetary transport of cosmic rays during transient events at different space/time scales. This paper introduces the detector and analyzes observations made over one year. After analyzing and correcting for atmospheric conditions, the study focuses on periodicities and modulations due to heliospheric phenomena. Two periods are observed: a 1-day period associated with Earth's rotation and spatial anisotropy of the cosmic ray flux, and a -30-day period due to solar impact and the rotation of the Sun. Through analysis and considering geomagnetic effects, the capability of the detector to observe anisotropies and other interplanetary modulations on cosmic ray flux arriving at Earth is determined.

Background model of phoswich X-ray detector on board small balloon

Abhijit Roy, Ritabrata Sarkar, Sandip K. Chakrabarti

Summary: The study thoroughly modeled the background counts observed in an X-ray detector at balloon altitude used for astronomical observations, utilizing Monte Carlo simulation to estimate detector background from various plausible sources. It was found that high energy particles and radiation from Galactic Cosmic Rays interacting with atmospheric nuclei are major contributors to background counts, with induced radioactivity in detector materials also playing a significant role. The research considered detailed 3D modeling of Earth's atmosphere and magnetosphere to calculate the radiation environment at balloon altitude and utilized a proper mass model of the detector to calculate background counts.

Summary: This paper reports results on the measurement of the cosmic-ray composition using the TALE air fluorescence detector, focusing on X-max distributions of showers observed over a wide energy range. The study shows that the composition of cosmic rays becomes heavier with increasing energy, consistent with a rigidity-dependent cutoff of events from Galactic sources. Additionally, a change in the cosmic-ray composition is observed at energies just above 10(17) eV.

Angular distribution of low momentum atmospheric muons at ground level

I. Briki, M. Mazouz, L. Ghedira

Summary: We report measurements of the angular distributions of low momentum atmospheric muons at 38 m above sea level for zenith angles between -60 and 60 degrees in the south-north direction. The muon detection was performed using two NaI(Tl) scintillation detectors mounted in coincidence. The integrated and differential muon flux were determined by analyzing the deposited energy spectra in the scintillators backed up by a Geant4 simulation of the experimental setup. The results are consistent with the cosn(0) distribution and fill the gap in the geomagnetic cutoff rigidity interval 8 GV < Pc < 14 GV where no similar measurements were performed before. We found that n = 1.88 - 0.12 P mu c in the domain of muon momentum cutoff P mu c < 1 GeV/c. These measurements are useful for muon studies requiring accurate integrated flux.

Polarized Radiation and the Emergence of Biological Homochirality on Earth and Beyond

Noemie Globus, Anatoli Fedynitch, Roger D. Blandford

Summary: This article explores the potential mechanism of cosmic radiation on the emergence of biological homochirality, emphasizing the impact of parity violation in weak interactions on polarization transport in cosmic ray showers. The study shows that muons retain their polarization even at energies that can initiate mutagenesis, potentially establishing a connection between broken symmetries in the standard model of particle physics and living organisms. The research calculates radiation doses from primary and secondary cosmic rays at various targets in the solar system and discusses implications for enantioselective mutagenesis as a driver of homochiralization.

A minimal model for understanding secondary cosmic rays

Ramanath Cowsik, Dawson Huth

Summary: We use a phenomenological approach in a minimal model to study the spectral intensity of secondary cosmic-ray particles such as positrons, antiprotons, Lithium, Beryllium, and Boron. Our analysis shows that at GeV energies, cosmic rays traverse a significant amount of matter in the regions surrounding their sources. This amount decreases with increasing cosmic-ray energy and becomes negligible beyond 100 GeV. In the interstellar medium, cosmic rays of all energies up to 105 GeV/n pass through approximately 1-2 g/cm2 of matter before entering the intergalactic medium. The bulk of positrons and antiprotons are generated in the interstellar medium. Additionally, cosmic-ray nuclei like C, N, and O produce additional amounts of Li, Be, and B nuclei with spectra similar to those of C, O, etc. The implications of these minimal model findings for gamma-ray observations and the importance of spatial and temporal discreteness of cosmic-ray sources for modeling cosmic-ray propagation are briefly discussed.

Universality of the muon component of extensive air showers

L. Cazon, R. Conceicao, F. Riehn

Summary: In extensive air shower experiments, the characteristics of muons in the shower, such as their number, arrival time, direction, and energy, are determined by the 3-dimensional distribution associated with the hadronic core of the shower. This distribution is influenced by parameters such as zenith angle, primary mass, and the hadronic interaction model used. By analyzing the production distributions of muons as a function of these parameters, the universality of their behavior in air showers can be studied.

Summary: The Radio Neutrino Observatory in Greenland (RNO-G) is searching for astrophysical neutrinos with energy > 10 PeV by detecting the radio emission from particle cascades in the ice. They present a simulation study showing how RNO-G can measure the energy of the cascades and estimate the energy of the incoming neutrino. The method uses differences in arrival times and electric field reconstruction to determine the neutrino interaction location and estimate the shower energy.

Summary: In order to detect the highest-energy neutrinos, polar-sited experiments have used impulsive radio emission resulting from neutrino interactions. This study suggests that 'fake' neutrino signals can be generated naturally through the triboelectric effect, specifically from wind blowing over granular surfaces such as snow. By analyzing data from past and current neutrino experiments, evidence of these backgrounds is found, characterized by specific wind velocity, frequency spectra, and discharge preferences.

Summary: The COSINE-100 experiment did not reach a conclusion regarding the observations claimed by the DAMA/LIBRA experiment due to the higher background of the NaI(Tl) crystals used in COSINE-100. To address this, the COSINE-100 experiment will be upgraded to COSINE-200, using ultra-low background NaI(Tl) detectors. The performance of an ultra-pure NaI(Tl) crystal detector produced at IBS, Korea is reported in this article.
