ALBUQUERQUE, N.M. — Sandia’s Z machine has produced plasmas that exceed temperatures of 2 billion degrees Kelvin — hotter than the interiors of stars. The unexpectedly hot output, if its cause were ...

The introduction of tritium is of high technical interest because a 50/50 mix of tritium and deuterium — the two isotopes of hydrogen — emits 80 times more neutrons, and 500 times more energy, than ...

Sandia's Z machine, built to generate radiation fields for validating models of nuclear weapons, has produced plasmas that exceed 2 billion degrees Kelvin — hotter than the interiors of stars.

Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a two-billion-year discrepancy ...

ALBUQUERQUE, N.M. -- Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid. The object of the ...
