【摘要】 研制成功煤（石油）井补偿中子法测井用的中子闪烁体对——ST1604、ST1605。其中子灵敏物质分别是Φ3、Φ4的多柱型⁶Li玻璃闪烁体,对热中子的透射探测效率分别为50—60％和～100％,而对⁶⁰Coγ射线探测效率<0.3％。此产品也可作其他强γ场中的高灵敏中子探测器。更多还原

【Abstract】 Glass scintil1ator pair types ST 1604 and ST 1605 for compensation neutron logging is developed. The neutron sensitive material used is multistick lithium glass scintillator 3 and 4 mm in diameter respectively. Thermoneutron detection efficiencies are 50-60% and-100% respectively. The detection efficiency for 60Co γ ray is lower than 0.3%. ST 1604 and ST 1605 may also be used as high sensitive neutron detectors in an intensive γ ray field.更多还原
