Abstract:
European Union intents to built a society based on knowledge. In these efforts a few new interesting research projects have been approved. In the Astrophysics and Particle Physics one of the major objectives is the building a underground detector, for cosmic rays, with a volume around 100000 cubic meters. In the frame of the FP7-INFRASTRUCURES-2007/212343 Project with the title „Design of a pan-European Infrastructure for Large Apparatus studying Grand Unification and Neutrino Astrophysics” (LAGUNA), three detectors could be built, namely: GLACIER, LENA and MEMPHYS. 7 underground laboratories, from 7 European countries, try to obtain the right to built one of these detectors, namely: Great Britain, France, Spain, Finland, Italy, Poland and Romania. The two institutions from Romania involved in this projects - National Institute for Nuclear Physics and Engineering and University of Bucharest, Faculty of Physics - proposed the salt mine "Unirea" from Slanic-Prahova as a possible place to install two of the three detectors: GLACIER and LENA. In this work we present the main general geological and physical arguments to place here these detectors. A good quality factor of the rocks, the existence of the large caverns, the solidity and stability of the site are the main arguments, especially for GLACIER detectors. In the case of the LENA detector a longer building of the site 200 m deeper than the present site seems to be necessary.
