Schematic view of the setup and cross sections from the (a) top and from the (b) side. (a = vacuum vessel with three viewports; b = plasma; c = microparticle; d = laser; e = polarizer, polarizing the light perpendicularly to the scatter plane; f = laser beam; g = collector rotating around the plasma; h = camera; i = photodiodes; j = pillars between electrodes; k = detection boundaries; l = electrodes; m = stepper motor to rotate the collector around the plasma; n = particle dispenser; o = modification of electrodes for particle confinement; p = spectrometer; q = optical fibre; r = connection to pumping system; s = gas inlet.)
