(Imaging Cosmic and Rare Underground Signals)
The ICARUS program concerns the usage of Liquid Argon (LAr) detector for studies of neutrinos from CNGS beam. The ICARUS detector filled with 600 tons of liquid argon, T600, has started data taking in 2010 (see neutrino eventGallery). The detector is placed at the undeground laboratory in Gran Sasso. The advantage of the LAr detector is its excellent spatial and calorimetric resolution which makes possible a perfect visualization of tracks of the charged particles.
The technology of the Liquid Argon Time Projection Chamber (LAr TPC), was first proposed by Professor Carlo Rubbia in 1977, was conceived as a tool for a completely uniform imaging with high accuracy of very massive volumes (several thousand tons). ICARUS is the first large scale detector, exploiting this detection technique. Originally, it was planned to perform the detector upgrade up to 2-3 ktons, by adding modules similar to the existing ones. In 2005 the decision was taken to change the concept in favor of a monolithic detector of this scale.As a Physics teacher I do believe in Great EINSTEIN!
