摘要:

在过去的二十年里,电荷耦合器件(CCD)已成功地用于几个高能物理实验。它们的高空间分辨率和薄敏感层使其成为研究短寿命粒子的绝佳工具。线性对撞机味道识别(LCFI)合作正在开发列并行CCD(CPCCD),用于未来线性对撞机的顶点探测器。CPCCD的读取速度比标准CCD快许多倍,大大提高了它们的操作速度。本文提出了一个计算电荷转移效率的解析模型。用分析模型确定的CTI值与全TCAD模拟的CTI值基本一致。分析模型允许有效地研究CTI在读出频率、工作温度和占用率等参数上的变化。

英文摘要:

Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying short-lived particles. The Linear Collider Flavour Identification (LCFI) collaboration is developing Column-Parallel CCDs (CPCCDs) for the vertex detector of a future Linear Collider. The CPCCDs can be read out many times faster than standard CCDs, significantly increasing their operating speed. An Analytic Model has been developed for the determination of the charge transfer inefficiency (CTI) of a CPCCD. The CTI values determined with the Analytic Model agree largely with those from a full TCAD simulation. The Analytic Model allows efficient study of the variation of the CTI on parameters like readout frequency, operating temperature and occupancy.
