Plasma Target Procedure | Procedure explained in Paper R Buschhaus et al. Plasma Sources Sci. Technol. 31 (2022) 025017.
(1) Clean targets: 1. Surface cleaning by Ar+ sputtering from ECR ion beam source. 2. SEEC & EEDF measurements with either ECR or Colutron source.
(2) untreated/air-exposed targets: 1. targets inserted into experimental chamber without prior surface cleaning by sputtering. 2. 2. SEEC & EEDF measurements with either ECR or Colutron source.
(3) in-situ oxidized targets: 1. Surface cleaning by Ar+ sputtering from ECR ion beam source. 2. oxidation of surface by O/O2 beam from OBS source. 3. 2. SEEC & EEDF measurements with either ECR or Colutron source plus simulataniously flow of O/O2. |
