X-ray induced fluorescence is demonstrated as a novel and fast method for measuring vapor pressures at high temperatures and high pressures. As such, it is an excellent complement to the effusion method, which is limited to lower pressures. High-ener

Measurements of the free‐free absorption coefficient in high‐pressure (50–400 psia) e‐beam‐excited rare‐gas plasmas have been used to deduce the temporal evolution of electron density in these systems. The measurements were carried out us
