タイル／ファイバーカロリーメータ

抄録

  Scintillating tile/fiber calorimetry is being developed intensively for high-energy hadron collider experiments. It takes advantage of high speed response of scintillator. Signals from scintillating tiles are readout by use of about 1 mmφ waveshifting fibers embedded in the tile hence the calorimeter dead space is minimized and the longitudinal segmentation is easily achieved. We describe the principle of the tile/fiber calorimeter and the status of R&D on fiber manufacturing methods, optimization of tile/fiber optics, and development of radiation hard scintillators. The performance as a calorimeter is evaluated using Monte Carlo simulations. Scintillating tile/fiber calorimetry is a good candidate for precision calorimetry in future hadron collider experiments.
