BH3105E型中子剂量当量仪研制

The Development of BH3105E Type Neutron Dose-equivalent Meter

研制成功BH3105E型中子剂量当量仪。仪器采用镉吸收棒法实现热中子至14 MeV区间等剂量当量测量;选用6Li玻璃闪烁体作为中子探测器;探头输出信号送至硬件电路进行处理。信号经主放大器、脉冲幅度甄别器、整形器由处理器进行计数采集。仪器系统软件设计实现了测量数据存储,采用串口协议与单片机进行通讯。

A new BH3105E Type Neutron Dose-equivalent Meter has been developed.The ＂multi-stick＂ absorption method is used for thermal-14 MeV neutron equal dose-equivalent detection,what gives a high neutron sensitivity of 5cps/μSv·h-1.RS-232 interface is accepted for signal communication.
