11 Cosmic Rays There are different types of cosmic rays: Galactic cosmic rays are probably accelerated in the blast waves of supernova remnants in the Milky Way Galaxy. Solar cosmic rays are produced in high energy processes at or near the Sun after a violent eruption at the Sun. Composition of galactic cosmic rays: Protons: 87 % Helium nuclei: 12 % Heavy atomic nuclei: 1 % Rainer Hippler INTAS
12 Galactic Cosmic Rays Galactic cosmic rays (GCR) originating from the Galaxy are accelerated to the highest energies known. Rainer Hippler INTAS
13 Solar cosmic rays Solar cosmic rays (SCR) originate from energetic solar particle events (SEP). SCR have a steeper energy dependence and do not extend to as large energies as GCR. Rainer Hippler INTAS
14 Spaceweather Storms SCR are ejected in the course of Coronal mass ejections (CME) providing hazards to the earth environment, in particular to satellites, aircraft and spacecraft crew and passengers, and to power lines on ground. Rainer Hippler INTAS

21 Objectives (I) Calculation and simulation of particle trajectories and detector response functions: (i) Performing multiple simulations of the particle traversal through the atmosphere and detectors. (ii) Preparing data bases for alternative input values of modeling algorithms, covering important energy ranges and particle types. (iii) Estimation of the detector response for different species of primary flux for the cosmic ray detectors and telescopes. Rainer Hippler INTAS

23 Asymptotic viewing directions Location: MuSTAnG Greifswald 13 (of 49) Viewing directions: V, N, E, S, W Detector size: 0.25 m 2 Rigidity spectrum: GV Rainer Hippler INTAS
24 Objectives (II) Detector hardware development: Existing networks of particle telescopes are unable to measure the energy of Solar Cosmic Ray (SCR) in the range 5-20 GeV. Modernization and enlargement of existing CR telescopes is foreseen, in particular: Modernization and enlargement of Aragats Multidirectional Muon Monitor (AMMM): We propose to enlarge the muon detector at Aragats station up to 120 m 2 and to equip it with modern electronics for precise measurements of the energy spectra of SCR up to GeV and with improved angular resolution. Enlargement of MuSTAnG: The University of Greifswald is presently setting up a Muon Telescope for Spaceweather Anisotropies at Greifswald (MuSTAnG). The telescope is financed by the European Space Agency (ESA). An enlargement to 24 m 2 is foreseen. Rainer Hippler INTAS
25 Objectives (III) Advanced Data Processing: Detector software development for data acquisition and advanced data processing. Establishing data bases attached to the Internet portal with fast access modes. Development of a fast-computing system for enhanced collaborative environments and enhanced data sharing. Calculation of the energy spectra of Solar Energetic Particle events: Calculation of Solar energetic particle events (SEP) Eurasian Muon and Neutron Telescope Network (Aragat, Bern, Greifswald, Tel Aviv) for Radiation and Spaceweather Storm Warning.
