Development of Prototype Neutron Flux Monitor for ITER 总被引:1,自引:0,他引:1
The prototype neutron flux monitor consists of a high purity 235U fission chamber detector and a “blank” detector, which is a fissile material free detector with the same dimension as the fission chamber detector to identify noise issues such as noise coming from gamma rays. The main parameters of the fission chamber assembly that have been measured in the laboratory are confirmed to approach the technological level of the International Thermonuclear Experimental Reactor (ITER) in the near future. This prototype neutron flux monitor will be further developed to become a neutron flux monitor suitable for the operation phase of D-D fusion on the ITER. 相似文献

气体电离探测器目前仍广泛用于核工业、核医学、同位素应用等领域。作为探测器中的电信号引出,电极支撑等则有不少采用陶瓷及陶瓷—金属封接,对于要求机械强度高、绝缘电阻大、高温性能稳定的探测器而言,必须采用陶瓷—金属封接。 气体电离探测器的种类繁多,用途广泛,要求陶瓷—金属封接件具有不同的几何尺寸和相应的结构。以下就在设计封接件中的一些要求,以及北京核仪器厂目前已有的封接件作一简单的介绍。 相似文献
