皮埃尔俄歇天文台表面探测器的性能

Performance of the Pierre Auger Observatory Surface Detector

Tiina Suomijarvi

摘要:

皮埃尔·俄歇天文台的表面探测器将由1600个切伦科夫水箱组成,对高能宇宙射线产生的空气簇射的地面粒子进行采样。到达时间由GPS获得,电力由太阳能电池板提供。阵列的建设已接近完成,大量探测器已运行三年多。本文讨论了探测器各组成部分的性能。给出了信号测量的准确性和触发稳定性。讨论了太阳能发电系统和其他硬件的性能,以及水的纯度和长期稳定性。

英文摘要:

The Surface Detector of the Pierre Auger Observatory will consist of 1600 water Cherenkov tanks sampling ground particles of air showers produced by energetic cosmic rays. The arrival times are obtained from GPS and power is provided by solar panels. The construction of the array is nearly completed and a large number of detectors has been operational for more than three years. In this paper the performance of different components of the detectors are discussed. The accuracy of the signal measurement and the trigger stability are presented. The performance of the solar power system and other hardware, as well as the water purity and its long-term stability are discussed.
