Characteristics of a Ce-Doped Silica Fiber Irradiated by a Neutron Field Up to 400 MeV

Abstract

A $\mathbf{200}\ \mu \mathbf{m}$ and $\mathbf{600} \ \mu \mathbf{m}$ diameter Ce3+ doped silica fiber, part of the UniBEaM charged-particle beam profiler system from D-Pace, were tested with 0 – 400 MeV neutrons at the TNF facility at TRIUMF, Canada. The detector's response to neutrons as a function of fiber length exposure was found to be linear, and the fiber was used to measure this neutron beam along its horizontal axis. This demonstrates the potential of the UniBEaM to measure neutron beam profiles.
