Abstract: | To investigate the interaction of dusty plasma with magnetized plasmas at divertor plasma
simulator, radial profiles of plasma density (ne) and electron temperature were measured in terms
of plasma discharge currents and magnetic flux intensity by using a fast scanning probes system
with triple tips. Dusty plasma with dusts (a generation rate of 3 μg s−1 and a size of 1–10 μm)
was produced via interactions between a high-power laser beam and a full tungsten target. As ne
increases, the scale of the effects of dusty plasma injection on magnetized plasmas was
decreased. Also, the duration of transient fluctuation was reduced. For numerical estimation of
plasma density perturbation due to dusty plasma injection, the result was ∼10% at a core region
of the magnetized plasma with ne of (2–5)×1011 cm−3 at steady state condition. |
