Development of a Radial TPC with MSGC readout for the STAR Experiment at RHIC
Abstract
The high particle density in Heavy Ion collisions at RHIC requires good pattern recognition and two track resolution capabilities. In STAR a TPC is seen as a tracking detector in the forward direction(2.2<η<4.5) the electrons drift in the radial direction, transverse to the magnetic field. The readout chambers use MSGC's with pad readout. With a"cool" gas a two track resolution of a few mm can be obtained. Results of electron diffusion and Lorentz angle measurements for Ar/DME and Ar/CO2 gas mixtures will be presented.
