Abstract

A set of two cylindrical multiwire proportional chambers, 2.2 meter long and 1 meter in diameter, are being built as part of the central tracking detector of the H1 experiment, at HERA. The chamber bodies are of sandwich type; the cathodes are segmented in pads. The transmission line, which is part of the sandwich, has an impedance matched to the preamplifiers. The electronic readout has been tested on a flat prototype chamber; the time resolution is well below the 96 ns bunch crossing time at HERA.

Technical aspects of the three major components of the H1 detector at the electron-proton storage ring HERA are described. This paper covers the detector status up to the end of 1994 when a major upgrading of some of its elements was undertaken. A description of the other elements of the detector and some performance figures from luminosity runs at HERA during 1993 and 1994 are given in a paper previously published in this journal.
