Plasma Target Properties
Aluminum (25 µm, purity of 99.999 %), titanium (127 µm, purity of 99.99 %), and copper (254 µm, purity of 99.9 %) targets with a size of 2.8 cm ×2.8 cm.
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.
