Abstract
For large TPCs in future experiments at the Large Hadron Collider (LHC , CERN) and at the Relativistic Heavy Ion Collider (RHIC, Brookhaven) it is of great interest to optimize the gas characteristics and the re adout geometry for the planned application. For this a large number of argon, neon and helium based gases with CH4, C2H6 and CO2 admixtures as quenchers were studied. The drift velocity and the transverse and l ongitudinal electron diffusion were measured for drift field strengths between 70 and 200 V/cm. Improvements of the readout chambers were te sted. Effects on the spatial and the two-track resolution are discusse d.
