A study is made of the ultra-short laser pulse irradiation of Ar cluster targets. Experiments have been performed with large cluster sizes and using very high laser contrasts, which have allowed clear and unambiguous observation of exotic inner-shell transitions in near-neutral Ar ions. The interaction of the main laser pulse with the unperturbed target is a necessary requirement for observing these lines. Our measurements are supported by kinetics calculations in which a very detailed atomic model is used. The calculations predict all of the spectral features found experimentally, and support the notion that the X-ray emission arises from many ion stages of the Ar plasma, from near-neutral through He-like ions, and from a range of plasma temperatures and densities.

Mult-code ${{it ab initio}}$ calculation of ionization distributions and radiation losses for tungsten in tokamak plasmas

We present calculations of ionization balance and radioactive power losses for tungsten in magnetic fusion plasmas. The simulation were performed within the framework of non-LTE code comparison workshops utilizing independent collisional-radioactive models. The calculations generally agree with each other, however, a clear disagreement with experimental ionization distributions at low temperatures, 2 keV $$<$$ $$T$$$$_{e}$$ $$<$$ 3 keV.
