Description
The European Spallation Source (ESS) is undergoing its next technical commissioning run, with the goal of achieving first Beam On Target (BOT). This milestone requires the full superconducting linac—27 cryomodules consisting of 26 Spoke, 36 Medium‑Beta, and 20 High‑Beta cavities—to achieve nominal parameters. This paper presents a statistical study of the Cold Tuning System (CTS) based on data from repeated tuning and detuning operations. The analysis focuses on tuning methodology and key parameters, assessing its repeatability and stability. The results provide a detailed characterisation of each CTS, ensuring stable cavity fields.
