Neutron Flux Measurements in Radiation Damage Experiments of ND-FE-B magnets by High Energy Electrons
Abstract: The demagnetization of permanent magnets used for a insertion device, due to 2 GeV electrons and secondary particles, has been studied and the reduction of those magnetic field strengths was observed in several magnet conditions. Coincidently, the neutron flux measurements was conducted using a threshold activation method for the study of interrelation between neutron flux and the demagnetization. The neutron flux from 1.2 MeV to 140 MeV was measured by using Bi, Ti, and In foils. It was also validated that Bi(n,xn) reactions is applicable as a measurement tool of an energy-informed neutron flux in high energy electron accelerator. The interrelation was discussed based on the obtained neutron flux.
