A review of the process of accumulating a positron (antielectron) plasma is presented. Positron sources and techniques to moderate, accumulate and characterise positrons are described, with examples of data collected using the positron beamline at Swansea University. Motivation is given for studying antimatter to explain the composition of the universe, in addition to some historical context. The use of positrons beyond research in fundamental physics is also discussed.
