摘要:

基于Timepix 3芯片的TPC的GridPix读出器是为将来在直线对撞机上的应用而开发的。GridPix检测器由一个带有集成放大网格的Timepix 3芯片读出的气体漂移体积组成。它的性能进行了研究,在一个测试束与2.5 GeV的电子。GridPix探测器可高效检测单个电离电子。Timepix 3芯片允许高采样率和时间行走校正。扩散被发现是在像素平面和漂移方向上的轨道位置测量上的主要误差,并且在像素平面中的系统失真低于10 $μ$ m。使用截断和,能量损失(dE/dx)的分辨率为4.1%,发现有效的轨道长度为1米。

英文摘要:

A GridPix readout for a TPC based on the Timepix3 chip is developed for future applications at a linear collider. The GridPix detector consists of a gaseous drift volume read out by a single Timepix3 chip with an integrated amplification grid. Its performance is studied in a test beam with 2.5 GeV electrons. The GridPix detector detects single ionization electrons with high efficiency. The Timepix3 chip allowed for high sample rates and time walk corrections. Diffusion is found to be the dominating error on the track position measurement both in the pixel plane and in the drift direction, and systematic distortions in the pixel plane are below 10 $μ$m. Using a truncated sum, an energy loss (dE/dx) resolution of 4.1% is found for an effective track length of 1 m.
