Muon-catalyzed fusion

Methods for obtaining muons, however, require far more energy than can be produced by the resulting fusion reactions. Muons decay rapidly due to their unstable nature and cannot be usefully stored.

Another benefit of muon-catalyzed fusion is that the fusion process can start with pure deuterium gas without tritium. Plasma fusion reactors like ITER or Wendelstein X7 need tritium to initiate and also need a tritium factory. Muon-catalyzed fusion generates tritium under operation and increases operating efficiency up to an optimum point when the deuterium:tritium ratio reaches about 1:1. Muon-catalyzed fusion can operate as a tritium factory and deliver tritium for material and plasma fusion research.
