Description
The Phase-2 upgrade of the CMS detector for the high luminosity era of the LHC, will install a new tracking system to cope with the increased pileup and track multiplicity. The inner layers of the outer tracker will be equipped with pixel-strip (PS) modules that have a high segmentation to provide an accurate position measurement. A PS module contains two types of silicon sensors, namely, strip and macro-pixel (PS-p) sensors. The PS-p sensor and its readout chip (the macro-pixel ASIC, or MPA) together form the macro-pixel sub-assembly (MaPSA). A rigorous quality control (QC) procedure has been developed and validated using prototype MaPSAs. This talk will describe the MaPSA QC setup and procedure, and the measurement results on the prototypes.
