摘要

康卜吞散射光子探測器是一個三維-鍺探測器的高空氣球實驗探測器。它被設計使用在天文，觀測光子能量介於0.2百萬電子伏特到10百萬電子伏特的發射線。康普頓散射光子探測器的數據讀出系統會將訊號放大,數位化並且根據不同的觸發訊號去讀出一系列的數據資料。 它也負責對飛行電腦溝通，接受飛行電腦傳達的指令然後做出動作，並且將讀出的數位數據傳入飛行電腦。這篇論文概括讀出系統的設計還有重要的科學與試成果。

The Nuclear Compton Telescope (NCT) is a balloon-borne telescope based on the 3D-positioning germanium detectors. It is designed to study astrophysical sources of gamma-ray emission in the energy range of 0.2 MeV to 10 MeV. The data readout system of NCT is designed to amplify, digitize and collect signals from a germanium detector according to a certain trigger scheme. It also has an interface to the NCT flight computer to receive commands and transfer data. This paper contains the design and the scientific test result of the readout system.
