倍增型有机光电探测器的研究进展

介绍了倍增型有机光电探测器的发展、工作机理、性能调控及相关的应用探索. 2015年张福俊课题组以单载流子传输通道的给受体混合(质量比约为100:1)薄膜为有源层，率先报道了界面附近受陷电子诱导空穴隧穿注入的倍增型有机光电探测器，并抑制了器件的暗电流密度.通过优化有源层厚度调控了界面附近受陷电荷的体分布，制备出超窄响应的倍增型有机光电探测器，并提出载流子注入窄化的新概念.利用三元策略及双层策略，制备出了宽响应倍增型有机光电探测器.利用光子俘获层调控器件的响应范围，以及利用倍增层获得了较大的外量子效率，将二极管型与倍增型器件的优势集中在一个器件中.引入光学调控层或将宽带隙材料引入有源层中，调控界面附近受陷电子分布，优化了器件的光谱形状，进而制备出响应光谱宽且平的倍增型有机光电探测器.将制备的倍增型有机光电探测器应用到心率监测、单像素成像及光开关等领域，取得较好的应用成果.     

论引力波探测器方位与引力波源方位间的关系

本文从计算棒状引力波天线的指向性函数出发,讨论了引力波源的方位和天线棒方位之间的关系,找到了从符合实验数据求出引力波源方位以及利用单一引力波探测器对连续引力波源的定位方法。所得的结果也适用于其他形式的一维引力波天线。一旦引力波探测器的灵敏度达到足以确定引力波强度时,本文的结果无疑对引力波天文学将是很有意义的。 关键词：     

Varying Track Etch Rates along the Fission Fragments＇ Trajectories in CR-39 Detectors

We determine the behavior of track etch rate VT along the tracks in CR-39 detectors exposed to fission fragments from ^252Cf source. CR-39 detectors are etched at 70℃ in different concentrations of Na2COa-mixed 6M NaOH solutions for different etching time intervals of 5-10min starting from 15 min up to 210min. Two values of track etch rate are determined along the fission fragment trajectories. The variation in VT is correlated with the energy loss rate of the fission fragment in the detector material.     

The KLOE Online Calibration System

Based on all the features of the KLOE online software,the online calibration system performs current calibration quality checking in real time and starts automatically new calibration procedures when needed.Acalibration manager process controls the system,implementing the interface to the online system,receiving information from the run control and translating its state transitions to a separate state machine.It acts as a “ calibration run controller“and performs failure recovery when requested by a set of process checkers.The core of the system is a multi-threaded OO histogram server that receives histogramming commands by remote processes and operates on local ROOT histograms.A client library and C,fortran and C application interface libraries allow the user to connect and define his own histogram or read histograms owned by others using an bool-like interface.Several calibration processes running in parallel in a destributed,multiplatform environment can fill the same histograms,allowing fast external information check.A monitor thread allow remote browsing for visual inspection,Pre-filtered data are read in nonprivileged spy mode from the data acquisition system via the Kloe Integrated Dataflow,privileged spy mode from the data acquisiton system via the Kole Integrated Dataflow.The main characteristics of the system are presented.
