Abstract:
The muons represent the EAS penetrating component and carry information about the mass and the energy of the primary cosmic particle, under the influence of the Earth magnetic field. The study of the high energy muon flux brings new informations regarding the muon multiplicities and the hadronic interaction models. The high energy muons represent, also, the main contribution at the natural radiation dose in underground which is important for low background measurements.
A new experimental facility for studies of high energy muons is proposed as underground facility in a salt mine in Slanic Prahova, Romania. Simulation studies using CORSIKA and MUSIC codes estimate the expected muon rate at aprox. 600 mwe (meter water equivalent). The energy cut off is estimated to be 150-200 GeV. A new mobile laboratory which permit measurements at surface and in underground is in pconstruction. For the future a muon experiment (MUON-UG) is planned to get installed in the mine to study hadronic interaction features as revealed by the flux and the multiplicities of high energy muons
