✦ Synopsis

We measured the upper critical field H c2 and the critical current density J c on neutron-irradiated MgB 2 samples and studied the effects of damaging on pinning mechanisms. We observed a strong enhancement of the upper critical field and great improvement of the critical current magnetic field dependence in an intermediate range of fluence. We demonstrated that the critical current increase is not only due to the H c2 improvement but the irradiation substantially changes the pinning force improving the critical current density at high magnetic field.

We report on the fabrication of MgB 2 neutron detector based on 10 B enriched superconducting MgB 2 thin films. The MgB 2 thin films were prepared by a multiple targets sputtering system. To increase the nuclear reactions of MgB 2 with neutrons, we used a 10 B-enriched target (97.0%). The MgB 2 mean
