摘要

我们提出了一种用背面照明CMOS图像传感器覆盖一层厚度为(20±5)μm的硼酸钠转换层来检测热中子的方法。中子引起的事件通过电荷阈值和几何考虑与光子引起的事件区别开来。该探测器在RA6反应堆的BNCT径向光束中辐照，以证明其在混合中子-伽马光束中的潜在应用。

Thermal neutron detector for mixed neutron and gamma beams using a commercial, boron-coated, CMOS image sensor

We present the detection of thermal neutrons using a Back Side Illuminated CMOS image sensor covered with a converter layer of sodium borate with a thickness of (20±5) μm. Events caused by neutrons are distinguished from events caused by gamma photons by a charge threshold and geometrical considerations. The detector was irradiated in the BNCT radial beam of the RA6 reactor to prove its potential use in mixed neutron-gamma beams.
