2 00 6 Spatial resolution of a GEM readout TPC using the charge dispersion signal
A large volume Time Projection Chamber (TPC) is being considered for the central charged particle tracker for the detector for the proposed International Linear Col-lider (ILC). To meet the ILC-TPC spatial resolution challenge of ∼ 100 µm with a manageable number of readout pads and channels of electronics, Micro Pattern Gas Detectors (MPGD) are being developed which could use pads comparable i...
متن کاملR&d on the Gem Readout of the Tesla Tpc
Studies for the TESLA TPC (Time Projection Chamber) with GEM (Gas Electron Multiplier) readout at DESY/Hamburg University are presented. Two test chamber setups are being operated. The studies include basic GEM performance, tracking and the determination of the resolution using different pad sizes and geometries. Our measurements show that chevron shaped pads lead to a better point resolution c...
متن کاملA TPC with Triple-GEM Gas Amplification and TimePix Readout
We present measurements with a GEM based TPC prototypes and the TimePix CMOS ASIC as charge collecting anode. Tests with a small prototype were performed in a 5GeV electron beam at DESY. It is shown that the point resolution for short drift distances is better than 20 μm. The achieved time resolution is better than 10 ns at 100MHz clock frequency. Furthermore, experimental studies with an enlar...
متن کاملTPC Performance in Magnetic Fields with GEM and Pad Readout
A novel charged particle tracking device, a high precision time projection chamber with gas electron multiplier and pad readout, is a leading candidate as the central tracker for an experiment at the International Linear Collider. To characterize the performance of such a system, a small TPC has been operated within a magnetic field, measuring cosmic-ray and laser tracks. Good tracking resoluti...
متن کاملSpatial Resolution Studies with a GEM-TPC in High Magnetic Fields
A large volume Time Projection Chamber (TPC) has been proposed as main tracking device at the International Linear Collider (ILC). Gas electron multipliers (GEMs) are studied as potential replacement of the conventional wire based gas amplification system of TPCs. This talk presents recent results from R&D activities with a small GEM-TPC prototype. The spatial resolution was measured for differ...
