X-IRRADIATED, GAMMA-IRRADIATED AND BETA-IRRADIATED Y-BA-CU-O SUPERCONDUCTOR STUDIED BY THERMOSTIMULATED EXOELECTRON EMISSION

The results of measurements of the thermostimulated exoelectron emissi on (TSEE) from Y1Ba2Cu3O7-delta superconductor are presented. They wer e recorded during heating in the temperature range 290-600 K supercond uctor previously irradiated with X-, gamma- and beta-radiation. Intera ction between electromagnetic or corpuscular radiation and the sample cause the creation of defects which give TSEE maxima for other tempera ture. The size of maxima depend only on a dose of absorbed radiation. Heating the sample at a temperature T greater than or equal to 550 K c ompletely removes electron traps which were created during irradiation .
