Unique combination of plasma temperature and density has been achieved with X-ray free-electron laser
In the first February issue of Nature, a Letter [1] appeared attracting an attention of specialists in areas of high-energy-density physics, laboratory astrophysics, inertial confinement fusion (ICF) and plasma physics. An international team of researchers headed by young Oxford physicist Sam Vinko created a unique state of matter by isochorically heating a thin aluminium foil using a tightly focused X-ray beam produced by the LCLS (Linac Coherent Light Source) free-electron laser in California.
