09:15 - 10:15
A brief overview is given about the research in the last hundred years, which formed our present understanding of cosmic rays. The basic properties of cosmic rays will be introduced and embedded in historical context.

The focus of ground-based gamma-ray astronomy lies in studying the origins of energetic Cosmic Rays (CRs) through the gamma-ray emission produced in the interactions of CRs with their environment. Since the first TeV sources were detected by ground-based instruments around 30 years ago the field has matured considerably, with over 200 Very-High-Energy (VHE, > 1TeV) sources currently known. Just within the last couple of years, considerable progress has been made particularly in the field of transient sources like GRBs and Novae. The successful scientific development of the field is also reflected in the phase transition from closed experiments to the Cherenkov Telescope Array, the first open astronomical observatory in ground-based gamma-ray astronomy, currently under construction.

Electrons (and positrons) are unique among the cosmic-ray species. Due to their relatively low masses, they are more strongly affected by the large-scale magnetic fields which govern cosmic-ray diffusion in the Galaxy. Source modeling indicates that a nearby accelerator such as the Vela supernova remnant could produce a clear signature in the energy spectrum of cosmic-ray electrons at TeV energies. In addition, some dark matter candidates could decay through a leptonic channel, producing a line signature in the electron spectrum at an energy governed by their masses. This talk will discuss the motivation for and the current state of direct observations of cosmic-ray electrons, mostly in the context of the Calorimetric Electron Telescope (CALET). CALET is a current, space-based cosmic-ray electron telescope on the International Space Station (ISS) designed for direct, calorimetric detection of electrons at 1 GeV–10+ TeV energies, gamma rays at 1 GeV–1 TeV energies, and cosmic-ray hadrons up to PeV energies. Electromagnetic calorimetry, detector calibration and response, and the detection and reconstruction of cosmic-ray events will be summarized in the context of CALET, and current results will be compared with those of other instruments, including DAMPE, AMS-02, and Fermi-LAT. Finally, the analysis of photon events and their similarities to electrons will be summarized.

Ground-based gamma ray detectors allows us to study the highest energy gamma rays whose flux is too small to measured by satellites. In this talk we will describe the physics of the extensive air showers and the techniques developed to separate the small number of gamma ray induced showers from the background of hadron induced showers.

Abstract: Magnetic-rigidity spectrometers, making use of the curved tracks of charged particles traversing strong magnetic fields in the bores of permanent or superconducting magnets, are among the most versatile tools available for cosmic ray research. As the only instruments that can determine charge sign except at very low energies, they are essential in antimatter measurements and searches. They are also the most sensitive means of distinguishing isotopes at energies above a few hundred MeV/nucleon. The requirements for a successful magnetic-rigidity spectrometer and its components will be reviewed together with a brief discussion of their history, important examples, and a review of important scientific results.
