Mezzanine board testing for the CMS Calorimeter Endcap upgrade
ORAL
Abstract
The High Granularity Calorimeter (HGCAL) is a significant upgrade to the Compact Muon Solenoid (CMS) detector that requires new hardware for detector controls and data readout. A mezzanine board was developed to expand the range of the HGCAL "engine" circuit boards by allowing one engine to connect to four sensor modules instead of the previous maximum of three. This project established a testing procedure to validate the board's key communication pathways, specifically the General Purpose Input and Output (GPIO) pins and the Analog to Digital Converter (ADC) pins of the lpGBT chip. These testing programs and their graphical user interface (GUI) will be used to quickly and simply ensure that approximately 240 mezzanine boards are fully functional before their installation in the detector.
