Drifting localization of ionization runaway: Unraveling the nature of anomalous transport in high power impulse magnetron sputtering
Description:
The plasma over the magnetron’s erosion “racetrack” is not azimuthally uniform but concentrated in distinct dense plasma zones which move in the {vector E}×{vector B} direction with about 10% of the electrons’ {vector E}×{vector B}/B{sup 2} drift velocity. The plasma zones are investigated with a gated camera working in concert with a streak camera for Al, Nb, Cu, and W targets in Ar or Kr background gas. It is found that each plasma zone has a high density edge which is the origin of a plasma-…
