Transport Across an X-Point in HiPIMS plasmas — •Martha Finke1, Achim von Keudell1, Dennis Krüger2, and Marc Böke1 — 1Fakultät für Physik und Astronomie, Bochum, Germany — 2Fakultät für Elektrotechnik und Informationstechnik, Bochum, Germany
Magnetized low pressure plasmas have a wide range of applications such as sputter deposition of metals and oxides or plasma thrusters for small satellites. In case of High Power Impulse Magnetron Sputtering (HiPIMS) the plasma currents may affect the magnetic fields. By combining two magnetrons with their magnets facing each other one obtains a specific topology of the magnetic field with an X-point, where we seek to find signatures of magnetic recinnection events. We investigate in the time-resolved behaviour of the plasma during the HiPIMS pulse using an ICCD camera and observe that the plasma igniting in front of the driven targen is strongly influenced by the magnetic field of the opposite magnetron.
