摘要

在加拿大TRIUMF的TNF设施中，对D-Pace的UniBEaM带电粒子束谱仪系统中$\mathbf{200}\ \mu \mathbf{m}$和$\mathbf{600} \ \mu \mathbf{m}$直径的Ce3+掺杂二氧化硅光纤进行了0 ~ 400 MeV中子的测试。发现探测器对中子的响应与光纤长度暴露成线性关系，并利用光纤沿其水平轴测量中子束。这证明了UniBEaM在测量中子束剖面方面的潜力。

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

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.
