First results from the CERES radial TPC

The CERES/NA45 experiment at the CERN SPS was upgraded in 1998 by the addition of a cylindrical Time Projection Chamber. The aim is to improve the mass resolution of e sup + e sup - pairs in the rho/omega/phi region to DELTA m/m < 2%. A progress report is given on the TPC performance during the 1...

Descripción
Sumario:The CERES/NA45 experiment at the CERN SPS was upgraded in 1998 by the addition of a cylindrical Time Projection Chamber. The aim is to improve the mass resolution of e sup + e sup - pairs in the rho/omega/phi region to DELTA m/m < 2%. A progress report is given on the TPC performance during the 1998 commissioning runs (laser rays, beam halo muons, and particles produced by proton/pi and lead beams hitting Pb and Au targets).
