The National Ignition Facility (NIF) neutron time of flight (NTOF) diagnostic will measure neutron yield and ion temperature in all NIF campaigns in DD, DT, and THD(*) implosions. The NIF NTOF diagnostic is designed to measure neutron yield from 1x10(9) to 2x10(19). The NTOF consists of several detectors of varying sensitivity located on the NIF at about 5 and 20 m from the target. Production, testing, and calibration of the NIF NTOF detectors have begun at the Laboratory for Laser Energetics (LLE). Operational tests of the NTOF detectors were performed on several facilities including the OMEGA laser at LLE and the Titan laser at Lawrence Livermore National Laboratory. Neutron calibrations were carried out on the OMEGA laser. Results of the NTOF detector tests and calibration will be presented.
国家点火装置（NIF）的中子飞行时间（NTOF）诊断系统将在NIF的所有氘 - 氘（DD）、氘 - 氚（DT）和氚 - 氢 - 氘（THD()）内爆实验中测量中子产额和离子温度。NIF的NTOF诊断系统旨在测量1×10⁹至2×10¹⁹的中子产额。NTOF由几个灵敏度不同的探测器组成，位于NIF上距离靶约5米和20米处。NIF的NTOF探测器的生产、测试和校准工作已在激光能量学实验室（LLE）展开。NTOF探测器的运行测试在多个设施上进行，包括LLE的欧米茄激光装置和劳伦斯利弗莫尔国家实验室的泰坦激光装置。在欧米茄激光装置上进行了中子校准。将展示NTOF探测器测试和校准的结果。 （注：原文中THD()这里的*不太明确其准确含义，翻译时保留原样）
