Description
The High Luminosity LHC upgrade mandates a comprehensive overhaul of the CMS Drift Tubes (DT) electronics due to trigger rates surpassing current capabilities. By leveraging advancements in optical and bandwidth technologies, this upgrade presents an opportunity to redefine the architecture of DT electronics. On-detector functions undergo streamlining to facilitate the relocation of data processing to a more accessible back-end environment. The On-detector Board for Drift Tubes (OBDT) is the critical component in this transition, integrating essential functionalities such as slow control and time distribution through LpGBT chips and VTRX+ optical transceivers. Notable design enhancements aim to facilitate integration into the CMS system, with specific attention given to the radiation-resistant components, such as the flash-based PolarFire FPGA from Microsemi. The deployment of OBDTs in a sector of the CMS alongside back-end prototypes adhering to the ATCA standard represents a notable milestone in this upgrade effort. Rigorous testing procedures are conducted to ensure the suitability of these systems for the demanding operating conditions of the HL-LHC, with a primary emphasis on functionality and reliability. This report outlines an innovative approach to DT electronics, promising enhanced performance in a challenging HL-LHC environment.
