Test beam results of the Megatile prototype for the CALICE AHCAL — •Anna Rosmanitz for the CALICE-D collaboration — Johannes Gutenberg-Universität Mainz
The CALICE collaboration develops several highly granular calorimeter concepts for a future e+e− collider, that are specialised for Particle Flow Algorithms.
The current design for the AHCAL consists of small, seperately produced scintillator tiles with a size of 3x3 cm2 read out by silicon photomultipliers (SiPM). They are separately wrapped in reflective foil and glued to the boards. In total, the AHCAL is going to have 8 million channels.
To facilitate the assembly process, the Megatile, a structured scintillator plate, was developed at the University of Mainz. Its advantage is that larger sections of 12x12 channels are produced at once with the channels separated by tilted trenches filled with reflective TiO2.
Different prototypes of the Megatile have been tested in test beams at DESY with electrons. This talk presents the light yield and cross talk results from this analysis.
