| dc.description.abstract | 本計畫旨在建構一粒子偵測器陣列以研究用此陣列偵測大氣中水平行進的緲子之可行性。我們從偵測器的製作和組裝開始，然後逐步完成了四支偵測器的各項基本特性之測試和量測。接著將這四支偵測器組裝成一組陣列。建構完成後即以此偵測器陣列進行了短期但連續的觀測。由觀測所得的資料，我們得以對水平行進（在天頂角約86.2∘~ 93.8∘的範圍內）及以小角度的向上或向下（在天頂角約77.3∘~ 84.8∘及95.2∘~ 102.7∘的範圍內）行進之緲子事例進行初步的分析及探討。實驗結果顯示，使用粒子偵測器陣列可以偵測到此類事例。我們也因此確認了此偵測方式確實可行。同時，實驗數據也顯示接近水平方向的緲子數量，雖比垂直方向的緲子數量少很多，但其通量比起微中子事例仍是高出很高。仍有許多細節還有待未來更進一步的研究。 | zh_TW |
| dc.description.abstract | The goal of this project is to build a particle detector array and to study the possibility of using this array to detect atmospheric muons from near horizon. First, we assembled the detectors, and then measured some basic specifications of those 4 detectors. We then design and construct a detector array. By using this detector array, we measured horizontal muons for 80 hours. Data collected during this experiment were then analyzed. Two types of events are presented, one is near horizontal direction (86.2? < ? < 93.8?, ? is zenith angle) ; the other types is slanted events (downward events 77.3? < ? < 84.8? or upward events 95.2? < ? < 102.7?). Events were detected in both cases, which prove this type of detector array can detect horizontal muons. These horizontal events are quite abundant, although much fewer then those events from the vertical direction. In conclusion, we have confirmed the possibility of using such particle detector array to detect horizontal muon events. There are many unknowns exist, which require some further researches. | en_US |
