“…Additionally the Tara central cell was stabilized by a divertor due to both the short circuiting of the azimuthal wave field [14] and the plasma compressibility. Stability was similarly demonstrated in the Lamex experiment [15] which used multiple divertors to form a 'picket fence' arrangement in a large mirror ratio axisymmetric mirror. However, Tara observed trapped particle modes that were localized to the axisymmetric plugging cells [16] which follow from an analysis similar to that given in equation (2).…”

“…[1][2][3] First described by Langmuir in 1923, electron emitting probes consist of a thin metal wire filament, typically made from tungsten, that is heated to high temperature with a current in order to achieve thermionic emission. 4 When immersed in plasma, a sheath forms around the surface of the filament.…”

A pulsed emissive probe technique is presented for measuring the plasma potential of pulsed plasma discharges. The technique provides time-resolved data and features minimal disturbance of the plasma achieved by alternating probe heating with the generation of plasma. Time resolution of about 20 ns is demonstrated for high power impulse magnetron sputtering (HIPIMS) plasma of niobium in argon. Spatial resolution of about 1 mm is achieved by using a miniature tungsten filament mounted on a precision translational stage. Repeated measurements for the same discharge conditions show that the standard deviation of the measurements is about 1–2 V, corresponding to 4%–8% of the maximum plasma potential relative to ground. The principle is demonstrated for measurements at a distance of 30 mm from the target, for different radial positions, at an argon pressure of 0.3 Pa, a cathode voltage of −420 V, and a discharge current of about 60 A in the steady-state phase of the HIPIMS pulse.
