设计研制了用于在线脉冲γ剂量测量装置的数据采集系统,并对其性能进行了测试,结果显示在稳态和脉冲输入时,输出电荷和输入辐射能量都具有良好线性。系统在西北核技术研究所的“晨光号”加速器进行了实验,并和热释光剂量计的结果进行了比较,相对偏差为±5%。数据采集系统的研制为在线测量单次脉冲γ剂量提供了一种新的技术途径。

A data acquisition system designed for on-line pulsed-gamma dosimetry was designed and tested for performance. The results show that both the output charge and the input radiant energy have good linearity at steady-state and pulsed input. The system was tested at the Northwestern Institute of Nuclear Technology “dawn ” accelerator and compared with the results of the thermoluminescence dosimeter, the relative deviation of ± 5%. The development of data acquisition system provides a new technical approach for on-line measurement of single pulse gamma dose.
