Description

The ENUBET ERC project (2016-2021) is studying a narrow band neutrino beam where lepton production could be monitored at single particle level in an instrumented decay tunnel. For this purpose we have developed a specialized shashlik calorimeter with a compact readout. The modules are composed of 1.5 cm thick steel absorbers coupled to 5 mm thick plastic scintillators. A matrix of 3 x 3 fibers run transversely with a density of one fiber/cm2 and an overall surface of about 10cm^2. Fibers are coupled individually to HD SiPM mounted on a custom PCB allowing reduce the dead zones between adjacent modules to an extremely small level compared to "fiber bundling" configurations. This setup allows a very effective longitudinal segmentation or e/pi separation. We will present the results of test beams performed in 2016-2018 at the CERN-PS East Area. We will also discuss the characterization of SiPM of different cell size (12μm and 15 μm) before and after being exposed to neutron fluxes up to 10^{12}/cm^2 at the INFN-LNL CN accelerator facility in June 2017. We have also successfully characterized at CERN a (12 X0) shashlik calorimeter based on polysiloxane scintillators. These are scintillators which come in liquid form, are poured around the fiber arrays and finally made solid with a thermal treatment.
