AbstractThe Tion diagnostic is a 1020-channel scintillator array on the Nova laser at Livermore. It measures the arrival time of single D-D or D-T neutrons at 27 m from the target with time resolution of 4 ns. The effect of neutron scattering has been obtained from Monte-Carlo neutron transport simulations and the scattered response is convolved with a Gaussian source to fit the data. The data analysis has been checked using targets which produce roughly equal numbers of D-T and D-D counts. The temperature obtained from Tion and from a current-mode neutron time-of-flight detector are in agreement for neutron yields above 1 × 109.
Tion诊断装置是利弗莫尔Nova激光装置上的一个1020通道闪烁体阵列。它测量单个D-D或D-T中子到达距靶标27 m处的时间，时间分辨率为4 ns。中子散射的影响已通过蒙特卡罗中子输运模拟获得，并将散射响应与高斯源进行卷积以拟合数据。数据分析已使用产生大致相等D-T和D-D计数的靶标进行了检验。对于中子产额高于1 × 10⁹的情况，由Tion和电流模式中子飞行时间探测器得到的温度是一致的。
