Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Wolfenden, Joseph (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.)
An optical beam loss monitor (oBLM) has recently been installed at the slow extraction region of the Super Proton Synchrotron (SPS) at CERN. The oBLM offers a new method for detecting beam losses at the SPS by utilizing the Cherenkov radiation emitted during beam loss interactions with an optical fibre. [...]

Upgrade and evolution of the ad target beam imaging system at CERN: a two-year performance analysis / Burger, Stephane (CERN) ; Roncarolo, Federico (CERN) ; Martínez Samblas, Javier (CERN) ; Gonzalez-Berges, Manuel (CERN)
During CERN’s Long Shutdown 2 (LS2) in 2022, the Anti-Proton Decelerator (AD) target area underwent major renovations, including a significant upgrade to its beam imaging system. The previous tube-based camera, used in a high-radiation environment, had limitations in sensitivity and resolution for continuous measurements.The upgraded design uses an innovative in-air light-emitting screen mechanically coupled to the AD target, monitored by a digital camera through a 20-meter optical line from a radiation-safe zone.

The Super Proton Synchrotron (SPS) beam loss monitoring (BLM) system at CERN, operational for several decades, currently comprises 286 Ionisation Chambers (ICs) around the SPS ring and approximately 144 additional detectors along various extraction lines (TT20, TT40, TT60, etc.). A complete renovation of the system is planned during Long Shutdown 3 (LS3), encompassing detectors, cabling, and acquisition electronics. [...]
