Time Resolution Study using Garfield++

In this project, different silicon sensors are simulated. The goal is to study how different parameters affect the time resolution considering different geometries of silicon detectors and front-ends. This will be important for the Vertex Locator Detector in LHCb, in future upgrades of the LHCb experiment. This study was made using the simulation tool Garfield++. For thicker pad sensors, it has been shown that the time resolution is better. High noise is shown to worsen time resolution. When varying the temperature, the low temperature sensors show an improved time resolution caused by a higher mobility of the electrons and holes. When comparing the pixel detector with the pad, the time resolution obtained was worse. The uncorrected resolution obtained for different thicknesses in a pixel detector is similar, due to a similar weighting field.
