The intensity and optical quality of RIBs are in general much poorer than those of stable beams. Because of this, very efficient and sensitive detection systems are needed. One such system consists of a gas volume that serves as both a sensitive detector and as the target itself. This is called an active target detector. These detectors, initially developed for high‐energy physics, found profitable applications in medium‐ and low‐energy nuclear physics as well, as confirmed by a successful series of experiments. The next generation of active target detectors builds on these experiments to go beyond, incorporating developments in gas detector technology and newly‐designed electronic systems. Since active target detectors possess intrinsic high detection efficiency, low detection threshold, excellent angular and position resolution, and the ability to reconstruct the kinematics of every event in three dimensions, they will play a vital role in future studies of most exotic nuclei. This talk will give an introductory overview on the topic of active target detectors.
