here it how others think its done;
Sandia’s Z machine exceeds two billion degrees Kelvin
Temperatures hotter than the interiors of stars
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 understood and harnessed, could eventually mean that smaller, less costly nuclear fusion plants would produce the same amount of energy as larger plants.
