Time Projection Chambers (TPC) have been part of particle physics since the 1970s. Good tracking, excellent pattern recognition and particle identification make them still attractive for future experiments as the International Linear Collider. As a result, research at DESY focuses on a large, high precision TPC with a material budget of 5% X0, capable of reaching a 100 μm single point resolution by utilizing Micro Pattern Gaseous Detectors compared to the multi-wire proportional chamber readout.
