Development and performance of Megatile prototypes for the CALICE AHCAL — •Rosmanitz Anna for the CALICE-D collaboration — Johannes Gutenberg-Universität Mainz, Institut für Physik
The CALICE collaboration is developing a highly granular Analog Hadronic Calorimeter (AHCal) for a future e+e- linear collider. At the moment, the detector consists of 3x3 cm2 scintillating tiles, singularly wrapped in reflective foil, glued to an electronic board, and read out by silicon photomultipliers (SiPM). To simplify and speed up the assembly process, the Megatile was developed at the University of Mainz as an alternative concept. It is built from a single scintillator plate with cut-out trenches that are filled with a TiO2-glue mixture to maintain the same granularity. Several full-scale prototypes have been built and tested with cosmic rays in the lab and with an electron beam. This talk presents the Megatile concept and its performance in particular in terms of light yield and cross talk.
