Abstract
Low temperature irradiation of polycrystalline ceramics YBa{sub 2}Cu{sub 3}O{sub 7} with high energy electrons (0.3 to 2.5 MeV) has three distinct consequences: - A critical temperature decrease, far more fast (in absolute and in relative value) than in usual metallics superconductors, - an extra trapping of vortex lines by irradiation defects, a weak trapping due to the superconductive coherence short length (20 A). - A critical current modification of the intergranulary transport: sometimes an increase at small dose (+ annealing eventually), but always a diminution at high doses. In this communication, we show in particular how alternate magnetic transmissivity measurements in function of an applied static magnetic field have allowed to determine the irradiation effect on the first penetration critical field, the critical current and the irreversibility line. 19 refs.; 5 figs.
