Advanced detector R&D is a critical enabler for future experimental programs in particle physics. Increasing luminosities, collision rates, radiation levels, and data volumes impose stringent requirements on spatial and temporal resolution, radiation tolerance, material budget, power efficiency, and system-level integration. In response, a coordinated European approach has been established within the European Strategy for Particle Physics, defining long-term priorities for accelerator- and experiment-driven detector innovation, documented by the ECFA Detector Roadmap. Based on it, the DRD program, consisting of eight Detector Research and Development (DRD) collaborations, provides a structured framework to address these challenges through focused, cooperative R&D across different sensor technologies like gaseous-, liquid, solid-state- and photon detectors, as well as calorimetry and quantum sensors, complemented by work on electronics and mechanics. Through strategic alignment, shared infrastructure, and cross-experiment synergies, the DRD program is positioned to mitigate technological risk, optimize resource utilization, and ensure the timely availability of mature detector solutions for next-generation collider experiments, while also advancing innovative ideas.
This talk provides an overview of the needs of current and future HEP experiments and the DRD program. It concludes with highlights of the speaker’s own R&D activities on monolithic pixel sensors, silicon carbide detectors, and their applications in medicine and dosimetry.
