We present new insight into the ongoing machine learning analysis of KASCADE experiment archival data, that contain air shower events with ∼ 1 − 100 PeV primary energy. The aim of the study is to improve the accuracy of high-energy cosmic rays mass composition reconstruction with respect to the standard KASCADE technique. We introduce five mass groups: protons, helium, carbon, silicon and iron nuclei and interpret the reconstruction process as a classification task. We employ a random forest technique as well as two promising neural network architectures — a self-attention perceptron and a convolutional neural network. These models are being trained with KASCADE CORSIKA simulations. We examine the behavior of the mass composition reconstruction for several hadronic interaction models and additionally check the credibility of our methods with a small "unblinded" part of the real KASCADE data.

Measurements of the natural radiation background, specifically in the upper troposphere and low stratosphere, are important in order to compare and eventually inter-calibrate different experimental set-ups, as well as to provide a reliable basis for improving the existing models related to the environmental radiation in the Earth’s atmosphere. Here, we report results from a new zero-pressure stratospheric balloon flight in the frame of the HEMERA-2 mission, obtained by measurements performed with a small portable device, (MDU)-1 Liulin. We derived the altitude profile of the atmospheric radiation in the Arctic region, namely in between Esrange Kiruna, Sweden and Rovaniemi, Finland. The preliminary analysis shows a good agreement between the measurements and Oulu models for atmospheric ionization and exposure to radiation.

The DArk Matter Particle Explorer (DAMPE) is a space-based particle detector launched on December 2015 from the Jiuquan Satellite Launch Center in China, and since then smoothly operating in a Sun-synchronous orbit. The main goals of the DAMPE mission include the study of the Cosmic-Ray Electron-positron (CRE) energy spectrum, the study of galactic cosmic-rays (CR), gamma-ray astronomy, and indirect dark matter search. The large acceptance and the detector figures make DAMPE able to measure the CREs and gamma-rays spectra up to few TeV, and cosmic-ray nuclei spectra up to hundreds of TeV, with unprecedented statistics and resolutions. An overview of the DAMPE mission will be presented, along with main results and ongoing activities, focusing on CR spectral measurements.
