Gaseous detectors are widely used in particle physics, rare-event searches, neutron instrumentation, and many other areas. They offer versatile solutions when precision measurements are required in large volumes, and with appropriate geometries and configurations, they provide good spatial resolution, timing information, and particle identification capabilities.

In this talk, I will review the evolution of gaseous detector technologies, illustrated with real-life examples from projects I have worked on, ranging from classic wire chambers to state-of-the-art micropattern gaseous detectors. The examples include Delay Wire Chambers (DWC) for beam monitoring at CERN test beam lines, the ATLAS Transition Radiation Tracker (TRT) collecting data since 2009, Micromegas detectors used in education at ELSA, B-10–based neutron-sensitive detectors being developed for future neutron sources, and a GridPix-based Time Projection Chamber (TPC) designed for rare-event searches.

I will review construction procedures, calibration and monitoring techniques, and Data Acquisition (DAQ) systems, supported by results from multiple test beam campaigns. Through these examples, I aim to provide a clear picture of how gaseous detectors are developed and operated in practice.
