  1. When the neutron decay constant is measured in the zero power assembly, the dt external neutron measurement system ( scintillator photomultiplier tube detector st - pmt ) may provide trigger - signal and time correlationship

    摘要在零功率堆上進行了衰變常數測量實驗中,建立外中子源dt中子測量系統可以為物理診斷系統提供觸發信號和時間關聯信號。
  2. 2 the design and manufacture of focs instrument system the foundation of commercial fiber optical chemical technique is to manufacture a fiber optical chemical instrument system. an instrument is assembled with xenon light as the source, bifurcate quartz fiber as the carrier for light, high precision photomultiplier tube for the conversion of light signal to electron signal and the 16 - digit multi - channels analog - to - digital card for collection of data

    生產人作者選擇氖燈為光源、設計聚焦系統,以石英分支光纖作為傳輸光信號介質,高精度光電倍增管檢測, 16位多道數據採集卡為a d轉換,採用visualbasic編寫windows平臺操作軟體,菜單提示,窗口人機對話,研製成功單通道光纖化學過程傳感儀器系統。
  3. A new method of absolute calibration of photodetector sensitivity based on spontaneous parametric down - conversion ( spdc ) biphoton field is described. the process of spdc is studied theoretically. the single photon detection probability and two - photon coincidence probability are derived and the calibration principle for photodetectors is explained. an experimental system has been set up. the sensitivity of a photon - counting photomultiplier tube was measured, and the results were compared with those obtained using conventional method

    討論了一種基於自發參量下轉換雙光子場絕對校準光電探測器靈敏度的新方法,著重推導了對自發參量下轉換過程中產生的單光子的探測概率和雙光子的符合速率,從而闡明了絕對測量光電探測器量子效率的原理.基於這一方法對光子計數型光電倍增管的響應靈敏度進行了測量,並將實驗結果與常規方法測得的結果進行了比較
  4. We adopt double alkali cathodal tube 9789qb, which was made by emi corporation in england, as our photomultiplier, whose spectrum ranges between 300nm to 650nm, with less noise counters and single - photon apices, which make it suitable as a single - photon - counter. the disparted - voltage device is designed in a reasonable way and the cooling system of iquefied nitrogen which makes it small in size, simple in structure, easy in processing, cheap in cost and good in performance

    該管型的光譜范圍在300 650nm ,具有暗計數少,有單光子峰的特點,適于做單光子計數器;本文的光電倍增管分壓器設計合理而冷卻系統採用液氮,該系統體積小、結構簡單、加工便利、成本低廉且性能良好。
