硅像素传感器的时间分辨率

Time resolution of silicon pixel sensors

Werner Riegler, Gianluca Aglieri Rinella

摘要:

我们推导出表达式的硅探测器的时间分辨率,使用朗道理论和PAI模型描述的电荷沉积的高能粒子。首先,我们使用的质心时间的诱导信号,并推导出解析表达式的三个组件有助于时间分辨率,即电荷沉积波动,噪声和波动的信号形状由于加权场的变化。然后,我们推导出表达式的时间分辨率,使用前沿歧视的信号为各种电子整形时间。文中还讨论了具有内增益的硅探测器的时间分辨率。

英文摘要:

We derive expressions for the time resolution of silicon detectors, using the Landau theory and a PAI model for describing the charge deposit of high energy particles. First we use the centroid time of the induced signal and derive analytic expressions for the three components contributing to the time resolution, namely charge deposit fluctuations, noise and fluctuations of the signal shape due to weighting field variations. Then we derive expressions for the time resolution using leading edge discrimination of the signal for various electronics shaping times. Time resolution of silicon detectors with internal gain is discussed as well.
