Journal ArticleDOI
First results on the hybrid photodiode tube
TL;DR: The performance of a new breed of light detectors based on a photocathode followed by a planar silicon diode working in the bombarding mode is reported in this article, which was developed by the LAA project in order to produce a fast light detector capable of covering a span of the more than 4 orders of magnitude of linearity required by the scintillating fibre and lead (spaghetti) calorimeter.
Journal ArticleDOI

TL;DR: In this article, the performance of a fine-grained 13-ton lead/scintillating-fiber calorimeter, in particular on its response to electrons, pions and multiparticles (reaction products from pions interacting in a target upstream of the detector).

TL;DR: In this paper, a variety of techniques for discriminating between (isolated) electrons and pions in a lead and scintillating fiber calorimeter without longitudinal segmentation are presented.

TL;DR: The lateral profile of the energy deposition in a prototype of a lead and scintillating fiber calorimeter, constructed in the framework of the LAA project at CERN, has been measured for both electromagnetic and hadronic showers in the energy range from 5 to 150 GeV.
