ACTIVITIES AND PLANS TERA Foundation (Created in1992) UgoAmaldi University of Milano Bicocca and TERA Foundation
1st program: design and Government approval of National Centre for carbon ions (and protons) Construction and commissioning by CNAO Foundation and INFN : 2005-2011 in Pavia Synchrotron building Hospital bulding
