TL;DR: The CERES/NA45 experiment at the CERN SPS was upgraded in 1998 by the addition of a cylindrical Time Projection Chamber (TPC) to improve the mass resolution of e+e− pairs in the ρ/ω/φ region to Δm/m < 2 as mentioned in this paper.

TL;DR: In this article, a two-dimensional position readout of wire chambers is described, where a cathode is segmented into small pixels that are read out in specific groups (pads), and the electronics are mounted on the outer face of the chamber with a chip-on-board technique, pushing the material thickness to a minimum.
