论文摘要
根据分析源和高达30个分段晶体的源和沿梁数据，讨论了Ganil上高级伽马跟踪阵列（AGATA）的性能。数据处理将详细描述。显示了单个探测器的性能。讨论了单个检测器的效率以及$γ$ ray跟踪后的效率。还提出了$γ$ - 雷跟踪的最新发展。将实验实现的峰值到总数与模拟进行了比较，显示了$γ$ - 射线跟踪阵列中背面划分的$γ$射线对峰值到量的影响。还给出了使用多普勒在梁内数据扩展的估计位置分辨率的估计。 源测量的角度相关性与不同的方法一起显示，以考虑$γ$ - 射线跟踪对角相关性归一化的影响。
The performance of the Advanced GAmma Tracking Array (AGATA) at GANIL is discussed, on the basis of the analysis of source and in-beam data taken with up to 30 segmented crystals. Data processing is described in detail. The performance of individual detectors are shown. The efficiency of the individual detectors as well as the efficiency after $γ$-ray tracking are discussed. Recent developments of $γ$-ray tracking are also presented. The experimentally achieved peak-to-total is compared with simulations showing the impact of back-scattered $γ$ rays on the peak-to-total in a $γ$-ray tracking array. An estimate of the achieved position resolution using the Doppler broadening of in-beam data is also given. Angular correlations from source measurements are shown together with different methods to take into account the effects of $γ$-ray tracking on the normalization of the angular correlations.
