HGCAL Assembly Support Software

The endcap calorimeter upgrade to the Compact Muon Solenoid will replace radiation damaged components and substantially improve the physics performance in preparation for the High Luminosity LHC. The detector will be comprised of over 100 distinct types of circuits boards, which will be placed in complex configurations on cooling plates, to form over 60 different types of "cassettes." These cassettes will then be stacked to form the final detector. We present work developing software to assist assembly technicians in the process of constructing the detector and the management and tracking of the components therein. The software presented consumes generic configuration files, and produces a variety of information related to the construction, including component lists, construction history, component scanning, and interactive 3D models. Though this software package is designed for the assembly of the endcap calorimeter, the generic configuration format means it is compatible with nearly any construction.
