Neutron Jammers (ニュートロンジャマー Nyūtoronjamā?) (also called N-Jammers) are devices used in the Cosmic Era timeline.
Technical Informations
An N-Jammer is a device which suppresses nuclear fission reactions by blocking the movement of free neutrons (nuclear fusion, which does not rely on neutron emission, would be unaffected by an N-Jammer).
