Summary
The Preshower Detectors form part of the CMS Electromagnetic Calorimeter and
are located in the endcap regions, just in front of the lead tungstate crystals.
They consist of two orthogonal planes of silicon strip sensors interleaved with
two planes of lead absorbers. A combined beam test of close-to-final
prototypes of the Hadron calorimeter, the crystal calorimeter and the
Preshower detector was performed in the summer of 2007. Calibrations were
made using muon, electron, and pion data and the combined crystal and
Preshower energy resolution was studied using electrons. Good signal/noise
performance was obtained in both sets of measurements.
