The 2026 International Conference on Instrumentation for Colliding Beam Physics (INSTR 2026) will be held at the University of Science and Technology of China (USTC) in Hefei, China, from October 12 to 16, 2026. The INSTR series is a major international instrumentation conference that typically takes place on a triennial basis, alternating with two other prestigious international instrumentation conferences: the Vienna Conference on Instrumentation (VCI) and the Pisa Meeting on Advanced Detectors (ELBA). The INSTR series is dedicated to reviewing the state of the art and recent advances in instrumentation for colliding-beam experiments and related fields, while fostering synergy across the particle and nuclear physics communities. 

This edition of the INSTR conference centers on frontier developments in collider experimental instrumentation, with special emphasis on instrumentation challenges and technological prospects for future colliders. The scientific program covers a broad range of topics: collider–detector integration, tracking and vertex detectors, particle identification, calorimetry, muon detectors, electronics, and trigger and data acquisition systems.
