Description

Permanent magnets are necessary materials for particle accelerator components. As the beam intensity of the accelerator increases, demagnetization effects in permanent magnet materials is becoming one of the important issues. In order to measure the demagnetization rate of the magnet materials such as NdFeB, SmCo, and Ferrite magnets, a neutron irradiation experiment in Kyoto University Research Reactor was carried out. By comparing the magnetization before and after the irradiation, relation between the demagnetization rate and irradiated dose were studied. In this presentation, results of the experiment will be presented.
