摘要

近年來，液態閃爍體探測器廣泛地應用於大型粒子探測器當中，如大亞灣微中子實驗。此類探測器多使用光電倍增管捕捉訊號及放大。其增益的程度與計算粒子能量有密切的關係，因此對其增益的校正及監控對實驗數據的可信度佔有關鍵的因素。在大亞灣實驗當中使用兩種校正及監控光電倍增管增益的方法－無光噪音及發光二極體光源。本論文比較在此兩種方法下取得的光電倍增管增益的差異程度。

Recently, liquid scintillation detectors are extensively used with particle detectors in many projects such as Dayabay. Mostly in such detectors, photomultiplier tubes (PMTs) are used for the detection of light. The gains of PMTs have closely relation with the calculation for particle energy, so it is crucial for calibrating the gains of PMTs. Such as Dayabay, there are two methods, Dark noise and LED light, to get the gains of PMTs. In this thesis, we discuss the discrepancy in the two methods.
