“…Two designs have been established [321,322], with the second one directly compatible with the current HBU design. For these scintillator tiles, promising first results with a molding procedure compatible with mass production have been achieved, demonstrating that large scale production of the required tiles is possible.…”

“…Simple fiberless coupling of the photon sensor leads to significant non-uniformities of the response, with a strong increase of the signal close to the SiPM [3]. Uniformity can be reestablished by special shaping of the scintillator, with a reduction of the material close to the photon sensor by a drilled hole or depression [3], [5]. In addition, the embedding of the SiPM into the tile leads to a significant increase in the overall signal.…”

Abstract-The recent availability of blue sensitive silicon photomultipliers allows the direct readout of blue emitting plastic scintillator tiles without the use of a wavelength shifting fiber. Such directly read out tiles, without light guides, are attractive for the use in highly granular calorimeters that use large numbers of individual cells and in other applications where very compact designs are needed. However, the total signal amplitude and the uniformity of the response can be problematic in such cases. We have developed a scanning setup to investigate the response of scintillator tiles with SiPM readout in detail. It was used to develop optimized scintillator tile geometries for highly granular hadronic calorimetry at future colliders and to investigate the feasibility of a SiPM readout for the trigger of the ATLAS ALFA luminosity detectors. We report on results obtained with specialized scintillator tile geometries, discuss first results obtained with directly coupled SiPM readout of the ATLAS ALFA trigger tiles and introduce the application of fiberless readout in an experiment to study the time structure of hadronic showers.

“…Different tile geometries were tested [4][5][6][7] and the tile design with the dimple on the tile big face was chosen, which provides both the suitability to mass production and appropriate uniformity of response. In this study, two tiles with dimple design from different materials were tested to compare their light yield and uniformity of response to minimum ionizing particles (MIP).…”

A new technological prototype of the highly granular hadron calorimeter for future collider experiments is being developed by the CALICE collaboration. The proposed baseline design of active elements considers scintillator tiles with a silicon photomultiplier readout. The light yield and uniformity of response of two tiles with dimple geometry from different producers were measured. The technology proposed for the ILD detector was used: each tile was individually wrapped in the reflecting foil and the SiPm was coupled directly to the dimple side of the scintillator tile. The measured response to minimum ionizing particle is almost twice better for BICRON408 scintillator than for polystyrene-based scintillator, while the estimated uniformity of response is better for the polystyrene-based scintillator tile produced by injection molding.
