abstract = {Series of experiments on tungsten (W) erosion and transport
in Argon (Ar) plasma were conducted at the linear plasma
device PSI-2. W erosion was measured with three independent
methods: WΙ spectroscopy, mass loss and quartz
micro-balance (QMB) deposition sensor. Consistent set of
data produced in these experiments was interpreted using the
3D ERO code simulations, which have reproduced all the main
trends observed. Influence of the physical model assumptions
(e.g. energy and angular distributions of sputtered
particles) was demonstrated. The effect of WΙ effective
quasi-metastable (MS) state population dynamics on
spectroscopy measurements is shown; the characteristic
relaxation time is determined. The measured physical
sputtering yields for W are close to the simulated data
obtained in the binary collision approximation (BCA)
approach (SDTrimSP code). The remaining discrepancies
between simulations and the experiment, mostly in
spectroscopy, are accounted to the uncertainties in the
plasma parameters and atomic data.},
