一体化总中子探测仪的研制

研制的一体化总中子探测仪将电子学部件小型化并集成于探测器顶部，与探测器组成一体，达到了体积小、移动方便的目的;用能转动方向的LED实时显示测量结果，通过计算机进行数据处理和报警显示;探头部分设计为具有一定的探测方向性。该探测仪可用于核视察及在车间、仓库进行长期监测，也可用于寻找在设备或核废物中能发射中子的核材料。仪器对前方相距10cm处的252Cf中子源的探测效率为0.92%。经过长期试用考验，总中子探测仪稳定可靠。

Development of Integrated Total Neutron Measurement System

An integrated total neutron measurement system was successfully developed. The miniaturized electronics components were fixed above the head of the detector. The system has a small body, so it is convenient to move. A rotatable LED was used to display the results, and it can also be controlled by computer for a long period measurement and assay. The system has special direction for measurement, can be used in nuclear inspection and monitoring facility storage, searching the neutron from nuclear materials in equipment or in nuclear waste. The neutron efficiency for 252Cf source at 10 cm in front of the system is 0.92%. The reliability and stability of the system has been proved for a long period test.
