Positron collector

Positron collectors, also known as antimatter receptors or colloquially as "pulsar leeches", were devices used to collect and organize antimatter for use as fuels in subspace vehicles. Most positron collectors were built around pulsar stars, which were the most sufficient source of antimatter.

The first positron collectors were developed by the Rakatans, and remained in use by all spacefaring species in the galaxy for millennia onward. The average positron collector were around five square kilometers in width. The Galactic Empire established a several self-sustaining positron arrays (systems of 100 or more positron collectors) around a number of pulsar stars in the galaxy. The largest positron collector to exist was the Antimatter Retrieval Ring, which was a large, ring-shaped positron collector built around the MAGNT-000 star and used by the Galactic Republic.

Dyson spheres (named after the ancient Republic scientist Dysonerus), which were massive superstructures used to collect all energy, including antimatter, emitted by stars.
