THE LIQUID ARGON TPC FOR THE ICARUS EXPERIMENT

The ICARUS project aims at the realisation of a large Liquid argon TPC to be run at the Underground Laboratories of Gran Sasso in Italy. An intense R&D activity has put on firm grounds this new detector technol ogy and experimentally confirmed its feasibility on a few ton scale. B ased on these solid achievements, the collaboration is now confident o f being able to build and safely operate a multi-kton detector. The re seach program of the experiment involves the systematic study of a wid e spectrum of physical phenomena covering many orders of magnitude in the energy deposited in the detector: from the few MeV of solar neutri no interactions, to the about one GeV of the proton decay and atmosphe ric neutrinos, up to the higher energies of neutrinos from accelerator s.
