Matter/Antimatter Reaction Assembly (M/ARA)

Known more commonly as the warp core, the Matter/Antimatter Reaction Assembly uses the controlled intermixing of deuterium and anti-deuterium to create energy in the form of plasma to power a starship's warp engines and other systems. At each end of the warp core, there is a reactant injector connected to either the ships deuterium tanks (the matter reactant injector or MRI) or anti-deuterium tanks (the antimatter reactant injector or ARI). These injectors control the rate of flow into the reaction assembly, and thus the amount of power being generated. The magnetic constrictor segments are the next major component of the M/ARA, connecting the reactant injectors to the reaction chamber. These segments use intense magnetic fields to channel the reactants at the right angle and pressure. The reaction chamber uses dilithium to mediate the matter/anti-matter reaction, and this is where the two substances annihilate one another to create plasma, which is channeled to the warp coils through the power transfer conduits.
