The remote operated vibrating sample magnetometer (VSM) for neutron irradiated samples has been developed. The maximum range of applied magnetic field is more than ±0.5/?0 A/m, and the resolution of magnetic moment is higher than 5 ×10-8 A?m2. The hysteresis loops of neutron irradiated samples were measured by this VSM, and the relationships between dose, which is one of epresentative irradiation parameter, and magnetic properties such as magnetic coercive force were examined. As result, it was revealed tha...

The remote operated vibrating sample magnetometer (VSM) for neutron irradiated samples has been developed. The maximum range of applied magnetic field is more t han ￡0.5/10 A/m, and the resolution of magnetization is higher than 5 x10-A'm2. The magnetization curves of neutron irradiated samples were measured by this VSM , and the relationships between dose, which is one of representative irradiation parameter, and magnetic properties such as magnetic coercive force. As result, it was revealed that there a...

Development of Remote Operated Vibrating Sample Magnetometerfor Evaluation of Irradiation Damage

Proper management of neutron irradiation damage on structural materials is important to ensure the Lealth of long-life fast breeder reactor (FBR) plants. Therefore, the effective index f or irradiation amage or the combination of those should be developed. In this study, the effects of dose, helium, nd the ratio of helium to dose on tensile and creep properties of FBR gra de type 316 stainless steel were investigated in the assumed irradiation damage range of FBR structural materials, that is, up to bout 1...
