Description

The CMS High Granularity Calorimeter (HGCAL) will be an
entirely new calorimeter for the high-luminosity phase of the LHC. It
comprises hexagonal silicon modules and scintillating tile modules with
silicon photomultipliers for readout, i.e., SiPM-on-tile modules. At
DESY, about 2,000 modules are going to be assembled, which requires
rigorous and automated quality control (QC) procedures. This
contribution will show the design and workflow of the developed QC
framework. Its modular approach allows the QC tests to be broken down
into a series of steps, which involve interfacing with specialized
hardware for data acquisition, studying the module's response when
changing configuration parameters, performing on-the-fly data analysis,
deriving calibration parameters, and automated reporting. The framework
offers a one-click solution to enable even non-expert users to execute
the QC procedures and determine if an assembled SiPM-on-tile module
meets the standards required for integration into the CMS HGCAL.
