Abstract

We report on an experimental study of a variety of techniques for discriminating between (isolated) electrons and pions in a lead and scintillating fiber calorimeter without longitudinal segmentation. Using information from the lateral shower development, from a pre-shower detector, from the time structure of the signals, or from a combination of these we measure pion rejection factors of up to several thousand while maintaining electron efficiencies of 95% or higher.

    It is also possible to use the time structure of the calorimeter signals themselves, for example for particle identification. This was demonstrated by the SPACAL Collaboration, who used the pulse width at 20% of the amplitude (FWFM) to this end [76] and measured very significant differences between the distributions of this variable for electrons and pions. In their case, the differences were considerably increased by the fact that the upstream ends of their fibers were made reflective.

    The shower time structure of steel absorbers shows advantages over the more dense tungsten [6]. A number of studies have previously addressed various aspects of the time development of hadronic showers [4,5,7,8]. Dedicated efforts have been made recently to measure the time structure of the hadronic showers and provide benchmarking input for the simulation tools [6].

    Since sampling fluctuations are a major limiting factor both for electrons and hadrons in well designed dual-readout calorimeters, it stands to reason to use the same high sampling fraction and frequency throughout the calorimeter. This uniform structure is also a crucial factor for eliminating the intercalibration problems that plague all longitudinally segmented calorimeter systems [7,8]. On the other hand, elimination of longitudinal segmentation offers the possibility to make a finer lateral segmentation with the same number of electronic readout channels.

    Our early work on the electron identification and the position resolution can be found in Refs. [4,5], where performances of a preshower detector, an Si-pad detector, and a lead-scintillation fiber calorimeter were evaluated using a test beam facility at KEK. Some of the previous studies by other groups can be found in Refs. [6–11]. The first 80 layers, called FCAL, make a 5×5 tower structure and are divided into four longitudinal sections (20 layers for each).
