我们研究了各种尺寸的细长闪烁体样品的定时和光产额特性。无论是光产量和时间分辨率下降指数相对于从一端的距离，反斜率参数的时间分辨率被发现是两倍的光产量。这是解释的光电子统计图片，这也可以解释所观察到的位置依赖性的时间分辨率的飞行时间计数器。
We have studied the timing and light yield characteristics of long and thin scintillator samples of various sizes. Both the light yield and the time resolution degrade exponentially with respect to the distance from one end; the inverse slope parameters for the time resolutions are found to be twice those of the light yield. This is interpreted in terms of a photoelectron statistics picture, which can also explain the observed position dependence of time resolution for time-of-flight counters.
