Description
To cope with severe radiation dosage and increased event pileup in a high luminosity environment, the existing endcap calorimeters of the CMS experiment will be replaced by a high granularity calorimeter (HGCAL). To make the most of the increased granularity, a precise placement of detector modules into the sampling planes is of utmost importance. This requires the module components’ physical dimensions and other features to be within strict bounds. We have developed a suite of programs for an optical coordinate measuring machine, used to perform various measurements on HGCAL baseplates, and have subsequently extracted quality assurance results from the recorded data. Our key objective is to verify the baseplates produced in India for their quality, such as flatness, thickness, and accuracy in fiducial placement, and to provide feedback to the manufacturers for better quality control. The talk will describe various baseplate features and their measurement methods.
