New developments in calorimetric particle detection
2018, Progress in Particle and Nuclear PhysicsCitation Excerpt :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.
Ultra-fast hadronic calorimetry
2018, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :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].
Particle identification in the longitudinally unsegmented RD52 calorimeter
2014, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :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.

2002, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :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).
