摘要:

The known solution for eddy-currents in a thick cylindrical conductor is compared with a computation from the surface-currents only. Such a computation requires only a two-dimensional array of discrete points, where the finite-element and other methods require a full three-dimensional, expensive array.

摘要:

Strontium-doped thermally pretreated NaCl crystals, X-irradiated at room temperature, were heated to 500°K for glow - curve measurements. The recorded glow curves show two definite peaks at 340 and 460°K. Study of the growth of these peaks with X-irradiation time indicates that the 460°K peak may be related to impurity - vacancy dipole in association with a negative ion vacancy situated in the dislocation region of the crystal.

摘要:

A B2. type Fe-40 at % Al ordered alloy was irradiated at 20 K either with fission neutrons or 2.5 MeV electrons. During isochronal annealing experiments of the radiation induced resistivity a different behavior was observed for the two irradiations. A decrease below pre-irradiated resistivity occurs after electron irradiation but not after the neutron one.

摘要:

A new model for hydrogen isotope exchange by ion implantation has been developed. The basic difference between our approach and previous work is that we include the depth distribution of the implanted species. The outstanding feature of this local mixing model is that the only adjustable parameter is the saturation hydrogen concentration which is specific to the target material and dependent only on temperature. The model is shown to give excellent agreement both with new data on H/D exchange in the low Z, coating materials VB2, Tie, TiB2, and B reported here and with previously reported data on stainless steel. The saturation hydrogen concentrations used to fit these data were 0.15, 0.25, 0.15, 0.45, and 1.00 times atomic density respectively. This model should be useful in predicting the recycling behavior of hydrogen isotopes in tokamak limiter and wall materials.

摘要:

Three physically distinct boundary conditions have been previously used in the real space computer simulation of point defects. The difference between them is discussed and their effect on vacancy formation energy is investigated.

摘要:

Thermal glow curves of thermally pretreated NaCl:Sr crystals have been recorded after irradiation with ultraviolet light at room temperature. The observed glow curves exhibit a prominent glow peak at 380°K only when the specimen is annealed and quenched from 750°C. This peak is attributed to the dipole clusters which disintegrate after heating the specimen beyond 380°K
