Depinning frequency in a heavily neutron-irradiated MgB2 sample

The magnetic-field-induced variations of the microwave surface resistance have been investigated in a heavily neutron-irradiated MgB2 sample, in which the irradiation has caused the merging of the two gaps into a single value. The experimental results have been analyzed in the framework of the Coffey and Clem model. By fitting the experimental data, we have determined the field dependence of th...

Cryogenic temperature performance of heavily irradiated silicon detectors

The charge collection e$ciency (CCE) of silicon detectors, previously irradiated with high neutron #uences, has been measured at 4.2, 77 and 195 K. The CCE recovery measured after 1.2]1014 n/cm2 is 100% at a bias voltage of 50 V. For 2]1015 n/cm2 the most probable signal collected for minimum ionising particles is 13 000 electrons, corresponding to 50% CCE, at a bias voltage of 250 V. Negligibl...
