Radiation hardness of permanent magnets of NdFeB in high energy neutron fields
Magnetic properties of NdFeB permanent magnet samples were measured before and after irradiation with conditions similar to conditions of DRIBs (phase 1) (FLNR, JINR) facility. Demagnetization of the samples after 8-day irradiation was found to be in the range of 17 to 87 %. Estimation of magnet �...

| Sumario: | Magnetic properties of NdFeB permanent magnet samples were measured before and after irradiation with conditions similar to conditions of DRIBs (phase 1) (FLNR, JINR) facility. Demagnetization of the samples after 8-day irradiation was found to be in the range of 17 to 87 %. Estimation of magnet 'life time' was made in the case of setting up these magnets on ECR ion source of DRIBs (phase 1) facility. Possible reasons of considerable demagnetization of the magnets are discussed. |
