建立渺子半衰期實驗

Abstract

舉凡目前世界各大型物理實驗，主要架構都包括1.感測器裝置、2. 前端訊號處理裝置、3.資料擷取系統、4.校正、5.蒙地卡羅分析、6.數據分析，今欲以渺子半衰期實驗，來實際進行一個完整而簡化物理實驗的設計操作。 本論文中說明由我自行設計的感測器的裝置、訊號處理裝置和資料擷取系統，並透過實際的訊號校正，證明資料擷取系統的穩定與準確性；透過蒙地卡羅模擬的實驗結果預測，以及實驗的數據分析，證明我們所裝置的渺子半衰期偵測器是可以完成、成功的測量出渺子半衰期 ns，與世界平均渺子半衰期2.19μs相合。

There are many big experiments in the world. Although they very complicated, most of them contain the following main components for a successful operation. These include 1.sensoring system 2.front end electronics 3.data acquisition system 4.calibration tools 5.Monte Carlo simulation 6.data analysis. Now we take a muon lifetime experiment for practice. It realistically demonstrates the procedure to construct a simplified physics experiment.. In this thesis, I will explain sensor setup, front end system and DAQ system which are designed by myself. By the calibrating processes, I will show that DAQ system is stable and dependable. From Monte Carlo simulating, I can predict the result of this experiment. At last by experimental data analysis, I will show that this set-up which I design is able to successfully measure the muon lifetime. This value agrees with the world average of muon lifetime 2.19μs.
