Overview of production and tests for the CALICE AHCAL technological prototype — •Phi Chau for the CALICE-D collaboration — Johannes Gutenberg-Universität Mainz, Institut für Physik

The CALICE collaboration is studying several calorimeter concepts, each one optimized for a usage of particle flow algorithm, for a future linear collider detector. One of these concepts, the analog hadronic calorimeter (AHCAL), is using a sandwich design with tungsten or steel absorber plates. Due to a particle flow algorithm optimized design, small detection units are needed. This results in a large number of channels (around 8.000.000) which is realized by a system composed of small scintillator tiles each read out by a silicon photomultiplier (SiPM). Construction and calibration within a suitable time window are challenging and have to be optimized. Also the design of the components has to be adjusted for mass assembly.
In 2017 the production and testing of a large technological prototype with 160 electronics boards and around 23.000 channels was started. This presentation will show an overview of the technological prototype and its production. Also various test results related to performance and quality checks will be presented.
