The PANDA experiment at the facility for anti-proton and ion research (FAIR) will study the strong interaction by precision spectroscopy. A detector system with excellent particle identification (PID) is therefore required. Charged hadron identification in the barrel region will be performed by a compact ring imaging Cherenkov detector based on the DIRC (Detection of Internally Reflected Cheren...

During the past ten years, gamma-ray Bursts (GRB) have been extensively studied in the keV-MeV energy range but the higher energy emission still remains mysterious. Ground based observatories have the possibility to investigate energy range around one GeV using the “single particle technique”. The aim of the present study is to investigate the capability of the Pierre Auger Observatory to detec...

In the future neutrino experiments, a beta-beam, which can produce pure electron neutrino beam, is expected to achive precise measurement of the neutrino oscillation parameters. In the νμ appearance measurement of a beta-beam, a detector does not need to identify particle charge and thus, a water Cherecov detector will be a candidate for the far detector. In this paper, we study the expected si...
