It is very important to measure the plasma performances of fusion reactors such as fuel ion density, plasma temperature, fusion power, fast neutron energy, and neutron flux. Various diagnostic systems are needed to measure fast neutron…

Matter in neutron star collisions can reach densities up to few times the nuclear saturation threshold and temperatures up to one hundred MeV. Understanding the structure and composition of such matter requires many-body nonperturbative…
Nuclear fusion promises a nearly limitless energy source, but achieving breakeven-where fusion output exceeds input-requires extreme plasma conditions and complex confinement systems. Here we propose an alternative approach based on…
The possibility that muon-catalyzed nuclear fusion at ambient temperature takes place in deuterated metals is analyzed theoretically. It is suggested that the muon-catalyzed deuterium-deuterium (dd) or deuterium-tritium (dt) fusion rate,…
