Particle detectors play a crucial role in advancing high-energy physics by enabling the detection, identification, and measurement of particles produced in high-energy collisions. These sophisticated systems integrate diverse technologies, such as tracking detectors, calorimeters, and muon systems, each optimized for precise spatial resolution, energy measurement, or particle identification. Recent upgrades in particle detectors, driven by the challenges of next-generation colliders like the HL-LHC, focus on enhanced radiation tolerance, higher rate capabilities, and improved resolution to handle unprecedented collision environments. This presentation provides an overview of current detector technologies, with an emphasis on novel developments in gaseous detectors, silicon trackers, and calorimetry, highlighting their applications, performance under extreme conditions, and contributions to uncovering new physics phenomena.
