Description
The completion of LHC Run 3 marks a natural milestone to assess the state of the art in beam diagnostics across the CERN accelerator complex and to define the instrumentation developments ahead. This contribution presents an updated R&D roadmap for the CERN Beam Instrumentation Group, built from a concise review of the current diagnostics, known operational limitations requiring upgrade or redesign, and needs collected from operation and future accelerator studies. Key R&D lines include next-generation electromagnetic pick-ups and monitors, non-invasive transverse and longitudinal beam profiling, and novel interceptive diagnostics based on low-density materials. A challenge shared by many of these developments is the need for detector and readout technologies that perform reliably in radiation environments, as illustrated for instance by the demanding requirements on beam imaging systems. This drives work on radiation-tolerant detectors and front-end architectures, high-dynamic-range, fast and robust DAQs. The roadmap also considers the growing role of automation, AI-assisted and ML techniques in future diagnostic systems design, operation and maintenance. The updated plan is positioned against the CERN timeline for full exploitation of the accelerator complex through end of life of the LHC and for the feasibility of next-generation facilities.
