AHCAL scintillator tile production — •Stephan Martens, Erika Garutti, and David Lomidze for the CALICE-D collaboration — Institute of Experimental Physics, Hamburg University
The CALICE collaboration develops a prototype particle flow calorimeter with excellent spatial and time resolution to investigate hadronic shower development with 3×3×0.3 cm3 granularity. The single channel of the AHCAL (analog hadronic calorimeter) prototype is a plastic scintillator tile wrapped in reflector foil and coupled to a silicon photomultiplier. The complete prototype requires about 24000 single channels, arranged in 40 sampling layers of about 0.5 m2 in size.
A Light Yield (LY) of about 16-18 photoelectrons per minimum ionizing particle, with a spread lower than 10% can be reached if the production of the single channels is automatized and accurately controlled.
We present the automatized production of AHCAL tiles and their characterization in terms of LY.
