Electrostatic Detection of Stainless Steel Dust Particles For Fusion Applications
Authors: P. Landy, C.H. Skinner and H. Schnieder
Abstract:
Dust accumulation inside next-step fusion devices poses a significant safety concern and dust diagnostics will be
needed to assure safe operations. An electrostatic dust detection device has been successfully demonstrated in the
National Spherical Torus Experiment (NSTX), Tore Supra and the Large Helical Device (LHD) and the detector’s
response to carbon particles was previously characterized in laboratory experiments. This paper presents laboratory
results showing that detection of stainless steel particle levels at levels as low as several μ g/cm2 is also possible.
