... the sub-Mev domain is very rich in physics, it is not trivial to perform deep and sensitive observations mainly because of the strong background induced in detectors by space environment, as cosmic rays, radiations belts, Earth albedo and Sun flares ...

... factor not completely suppressed by screening, namely interna l temperature (other non-suppressed local factors ­ the magnet ic field and cosmic rays proved to be not influencing on the detectors within their sensit ivit y at all) leads to correlat ion ...

... of rapid optical flashes of astrophysical origin, which is being performed by detecting the stellar-like ob jects visible on several consecutive differential images (to filter out sporadic noise events and cosmic rays) and not changing their position ...

... first shield against the radioactive emissions of the rocks and the environment that surround the facility and as a detector of the scarce residues of cosmic rays that cross the more than one thousand meters of rock under which the laboratory is located ...

... The energy deposited by protons and heavy ions present in Earth radiation belts, Solar flares and Galactic Cosmic Rays was estimated which can results in degradation of device performance by the creation of electron-holes pairs. ...
