Automatic assembly and test of CALICE second generation SMD readout boards — •Phi Chau for the CALICE-D collaboration — Johannes Gutenberg-Universität Mainz

The CALICE collaboration is developing an analog hadronic sampling calorimeter (AHCAL) for the International Linear Collider (ILC) using scintillator with silicon photomultiplier (SiPM) readout. Due to an optimization of the design for particle flow algorithm, small detection units are necessary. This leads to a high number of channels for the AHCAL (in total around 8.000.000) which represents a challenge for the construction and calibration in a suitable time window. To assure a fast assembly of the detection units the design of the readout board are optimized for an automatic assembly process. This presentation will show the automatic assembly of this optimized second generation readout boards (6 boards x 144 channels) and the very good performances of these boards measured in an integrated cosmic ray test stand. Also preparations for the 2017 assembly run of a large number of readout boards (with around 20.000 channels) are shown.
