Light yield characterization of single channels for the AHCAL — •Saiva Huck for the CALICE-D collaboration — Universität Hamburg

The light yield of the active single channels for the Analog Hadron Calorimeter (AHCAL) was characterized and compared.
The AHCAL is a highly granular prototype hadron calorimeter with 8 million single channels designed by the collaboration Calorimeter for Linear Collider Experiment (CALICE) for the International Linear Collider (ILC). One channel consists of a 29.60×29.60×2.98 mm3 plastic scintillator tile which is wrapped in reflective material and read out via a Silicon Photomultiplier (SiPM).
The light yield of scintillator tiles from different producers, wrapped in different materials and read out by SiPMs from 3 producers was measured as function of SiPM voltage using electrons from a 90Sr source at the Institute for Experimental Physics of the University of Hamburg. The results were evaluated with respect to the requirements of the ILC.
A number of combinations were found which fulfill the light yield goal of the CALICE collaboration and can be used in the AHCAL prototype.
