Description

The High-Luminosity Large Hadron Collider (HL-LHC) upgrade, expected to begin in 2026, will reach higher instantaneous luminosities and collision rates in an effort to explore new physics beyond the Standard Model. The current CMS Tracker will be fully replaced, and the new silicon tracking system will contain an Inner Tracker and an Outer Tracker. The Phase-II Outer Tracker (OT) is designed to withstand increased radiation levels and data input, and it will include 5,592 pixel–strip (PS) and 7,608 strip–strip (2S) sensor modules. Module production is distributed across seven international centers, necessitating standardized procedures for testing and quality grading. Testing of modules requires a device, such as the burn-in box, that replicates the temperature cycling conditions that modules must be able to withstand, with test data recorded in ROOT files. The Phase-II Outer Tracker Analyzer of Test Outputs (POTATO) is a software developed in C++ that evaluates the quality of modules by analyzing and grading ROOT files and storing results in a centralized database. Once completed, POTATO will allow technicians to analyze characteristics, such as noise, of specific modules and effectively assess global module production. This presentation will discuss my contributions toward enhancing POTATO’s grader functionality and assisting in module production, including inspections and tests of module components, during my experience at Fermilab.
