“…Large area photosensors directly coupled to the scintillator provide longitudinal segmentation at the price of introducing dead areas [17]. In calorimetric applications [12][13][14] Silicon PhotoMultipliers (SiPM) offer performance comparable with conventional PMT but can be miniaturized down to the scale of a SMD component, whose size can be matched to the diameter of the WLS fibers [18].…”

A: An iron-plastic-scintillator shashlik calorimeter with a 4.3 X 0 longitudinal segmentation was tested in November 2016 at the CERN East Area facility with charged particles up to 5 GeV. The performance of this detector in terms of electron energy resolution, linearity, response to muons and hadron showers are presented in this paper and compared with simulation. Such a fine-grained longitudinal segmentation is achieved using a very compact light readout system developed by the SCENTT and ENUBET Collaborations, which is based on fiber-SiPM coupling boards embedded in the bulk of the detector. We demonstrate that this system fulfills the requirements for neutrino physics applications and discuss performance and additional improvements.

“…The INFN SCENTT Collaboration has developed an ultra-compact module (UCM) where every single fiber segment is directly connected to a Silicon PhotoMultiplier (SiPM) thus avoiding dead regions due to fiber bundling with a net improvement in the homogeneity of the longitudinal sampling. An extensive experimental campaign ( [42,43,44,45]) at the CERN-PS has followed within the ENUBET Collaboration. The UCM concept has also been adopted for the polysiloxane based shashlik calorimeter described in this work.…”

We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a ∼ 6×6×45 cm 3 (13 X 0 depth) prototype. A Wavelength Shifting fiber array of 36 elements runs perpendicularly to the stack of iron (15 mm) and polysiloxane scintillator (15 mm) tiles with a density of about one over cm 2 . Unlike shashlik calorimeters based on plastic organic scintillators, here fibers are optically matched with the scintillator without any intermediate air gap. The prototype features a compact light readout based on Silicon Photo-Multipliers embedded in the bulk of the detector. The detector was tested with electrons, pions and muons with energies ranging from 1 to 7 GeV at the CERN-PS. This solution offers a highly radiation hard detector to instrument the decay region of a neutrino beam, providing an event-by-event measurement of high-angle decay products associated with neutrino production (ENUBET, Enhanced NeUtrino BEams from kaon Tagging, ERC project). The results in terms of light yield, uniformity and energy resolution, are compared to a similar calorimeter built with ordinary plastic scintillators.

“…UCM prototypes have been characterized with cosmic rays and with charged particles (e/π/µ) in the 1-5 GeV range at the CERN-PS East Area facility (T9 beamline) in several exposures in 2016 (July-November) and 2017 (August-October) [11,12,13].…”
