Chasing Time: Evaluation of Clock Stability  towards LHCb Upgrade
Clock distribution within the current LHCb Timing and Fast Control (TFC) system relies on a custom architecture that lacks comprehensive stability evaluation across proposed alternatives. As the system prepares for an upgrade in Run 5, achieving reliable synchronization and monitoring at high precision becomes critical. This project focuses on developing and deploying an automated, modular testing infrastructure to evaluate the stability of different timing architectures. Cross-instrument measurements and runtime analysis techniques are used to assess signal behavior along the critical path. The results so far provide quantitative insight into clock phase behavior and hint the technological direction for the upgraded TFC system - opening the door of possibilities of subsequent testing and evaluation.
