The Z machine is the most powerful source of X-rays on Earth, located at Sandia National Laboratories in Albuquerque, New Mexico, USA. It's a type of pulsed power machine that generates extremely high temperatures and pressures by delivering a rapid pulse of electrical current to a target.
This intense energy release creates conditions similar to those found in nuclear fusion reactions and the cores of stars, allowing scientists to study phenomena like nuclear fusion, high-energy-density physics, and astrophysics.
