摘要

Using pulsed sources of 14‐MeV neutrons (dose ∼109 neutrons/cm2) and fission neutrons, an investigation of short‐term annealing in silicon has been performed. In n‐type material, for approximately equal amounts of stable damage, the amount of unstable damage at 5×10-2 sec was ∼3.0 times greater for 14 MeV than for fission‐neutron irradiation. Considering that the ratio of stable damage for equal neutron fluences is ∼2.8, the total and unstable damage ratios at this same time, for equal neutron fluences, are ∼4.6 and ∼8.5. Although the available dose of 14‐MeV neutrons was small, it produced about a factor‐of‐two change in the carrier lifetime of high quality bulk material. No differences in the annealing curves were observed for fission‐neutron irradiations varying by two orders‐of‐magnitude in dose, suggesting that the data obtained for 14‐MeV neutrons would also be valid at higher doses.
