TPC with MPGD Readout

Participants: CERN, DESY, GSI, NIKHEF, UHH; ESR: 3 × 3 yrs (contact person: T. Behnke, DESY)

Large volume tracking for ILC and PANDA at FAIR using MPGD and pixel readout.

The Time Projection Chamber (TPC) is the detector of choice for large volume tracking with minimal material with highest information density. It is used in the ALICE experiment at the LHC and will be a key technology for the next generation of experiments e.g. at FAIR (PANDA) and at the International Linear Collider. In order to cope with the enormous particle densities and data rates, the TPCs will need to be equipped with micro-patterned ampli­fication, gating and readout structures.

All 3 ESRs will work on technological feasibility and prototype studies which will be realized in the frame of existing large experimental collaborations. For PANDA, a GEM-TPC will be tested in the running experiment FOPI. DESY and NIKHEF are pursuing the development of a large high precision TPC as the main tracker for a detector at ILC. A large prototype is being constructed in the framework of the EC-funded EUDET project, which will serve as a detailed test of large MPGD detectors and demonstrate their capabilities for large scale applications. The ESR at NIKHEF will participate in a particularly innovative development, namely the creation of an amplification grid directly on the readout chip by advanced wafer post-processing techniques.
