Operation and Noise Measurement of Functional 2S Modules for the CMS High Luminosity Upgrade

For High Luminosity LHC, the entire tracker detector of the CMS detector will be ex- changed as part of the Phase-II Upgrade. This upgrade aims to improve particle iden- tification, momentum resolution, and vertexing resolution for enhanced physics studies at the HL-LHC. This upgrade will include an inner part (Inner Tracker with micro pix- elated Modules) and at larger radii the Outer Tracker with two different module types (macro pixel and strip Modules). Noise measurement plays a crucial role in the eval- uation and optimization of detector performance in High-Energy Physics experimental measurements. This study focuses on the operation and noise measurements of func- tional 2S Module w.r.t temperature. The operational temperature test was performed in a dedicated Burn-in setup that works with well-controlled operational conditions. A dedicated monitoring setup for the burn-in setup is developed as part of a project that is discussed in detail. The results of this study provide valuable insights into the noise characteristics of the 2S Module Outer Tracker and offer guidance for potential improvements in the detector assembly and operational conditions. The findings con- tribute to the ongoing efforts to enhance the performance of the CMS tracker, enabling more precise measurements of particles detection by reducing noise as the function of temperature.
