Use of Cherenkov counters in experiments at accelerators for particle identification

The key properties of Cherenkov radiation are briefly discussed, together with various types of Cherenkov counters used to identify relativistic particles in accelerator studies. Specific examples of the application of Cherenkov counters in experiments are discussed. Particular attention is given to the role of Cherenkov counters in antinuclei observations, including the discovery of the antiproton.
