Electron Radiation Defects in TaC1−x and TiC0.97
The electrical resistivity changes of TaC0.99 and TaC0.80 have been measured at 21 K during irradiation with electrons of incident energies ranging from 2.5 to 0.25 MeV: a non-zero production rate is observed, even at the lowest energies. The recovery of defects was followed up to 400 K for TaC0.99 and TiC0.97 irradiated with 2.25 MeV electrons and up to 160 K for TaC0.80 irradiated with 0.75 MeV electrons. The results are compared to fast neutron radiation damage data. For TiC0.97 and TaC0.99, the contributions of the different defects to the production rates and recovery spectra are tentatively separated, and a rough estimate of Frenkel pair resistivities is given.
