Development and Characterization of a Radiation-Tolerant Power Supply for Beam Instrumentation
Year: 2026
Type: article
Abstract: CERN’s Beam Instrumentation Group is developing a mini-crate to host the future Beam Loss Monitor (BLM) and Beam Positioning Monitor (BPM) systems acquisition electronics at HL-LHC and SPS accelerators. For this purpose, a new power supply has been designed to meet the low noise requirements, high reliability, and availability standards for these harsh radioactive environments. This design makes use of CERN-developed ASICs and radiation-tolerant qualified COTS and follows a modular architecture for quick interventions and safe handling. The paper presents the design, prototype characterisation results, identified issues, and mitigation methods to achieve the required radiation tolerance.
