In this work we present a wide spectrum of ac/dc magnetic and magneto-optical characterizations of Bi2Sr2Ca2Cu3Ox (BSCCO) tapes and MgB2 tapes, before and after irradiation by means of high energy ions. The fluences were about 1011 ions/square centimeter. BSCCO tapes were irradiated up to 15% of their thickness by means of 0.25 GeV gold ions (Tandem facility energy ); the penetration depth was evaluated by TRIM simulations. In such tapes there is a decrease of critical temperature of about 0.5 K [1,2,3]; a large sensitivity to the high energy ions is exhibited, showing up in a significant enhancement of critical currents as well as in a large shift of the irreversibility line towards high temperatures (clear signatures of Bose-glass-like transition are present).
