Simulation Studies for a Time Projection Chamber at the ILC

The International Linear Collider (ILC) is planned to be the next large accelerator. The ILC will be able to perform high precision measurements which need to be matched by the detector performance. To optimise the detector design, detailed simulation studies are needed. A high resolution Time Projection Chamber (TPC) with gas amplification based on Gas Electron Multipliers (GEMs), is one of the options for the main tracking system at the ILC. In this book a detailed simulation tool to study the performance of a TPC is described. Its goal is to find the optimal settings to reach an excellent momentum and spatial resolution. The results achieved with the simulation are compared to data acquired with a TPC prototype. The framework is then used to carry out some exemplary studies to test the performance of a TPC at the ILC. The detailed simulation of the amplification structure using GEMs allows to also address the issue of ion backdrift. The results are compared to the design goals of the TESLA Technical Design Report. §This book is mainly addressed to the physics community involved with detector development, research for the ILC or an interest in detector performance and issues.
