11. Studies of cosmic rays with the anticoincidence system of the PAMELA satellite experiment
Sammanfattning : PAMELA is a satellite-borne experiment designed to study the charged component of the cosmic radiation of galactic, solar and trapped nature. The main scientific objective is the study of the antimatter component of cosmic rays over a wide range of energies (antiprotons: 80 MeV–190 GeV, positrons: 50 MeV–270 GeV). LÄS MER
12. Positrons and electrons in the cosmic radiation measured by the CAPRICE94 experiment
Sammanfattning : .... LÄS MER
13. The GLAST Satellite Calorimeter
Sammanfattning : The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. LÄS MER
14. Background radiation and soft errors in CMOS circuits
Sammanfattning : Background radiation in natural environments from ground level to airplane flight altitudes consists of electrons, neutrons, protons, pions, muons, and other types of particles. These particles originate either from cosmic rays or from radioactive decay. LÄS MER
15. Molecular gas and ionizing radiation in star-forming galaxies
Sammanfattning : In cosmic history, some of the major changes such as reionization were driven by baryons (i.e. the stars and gas in galaxies), despite the fact that they contribute only few percent to the total mass-energy budget in the Universe. LÄS MER
