• VUV-diagnostics of low temperature hydrogen plasmas 

  Komppula, Jani (University of Jyväskylä, 2015)

• Photoelectron emission induced by low temperature hydrogen plasmas 

  Laulainen, Janne; Kalvas, Taneli; Koivisto, Hannu; Kronholm, Risto; Tarvainen, Olli (AIP Publishing, 2018)

  Experimental results of low temperature hydrogen plasma induced photoelectron emission measurements comparing two different plasma heating methods are summarized. By exposing the samples to the vacuum ultraviolet radiation ...

• Photoelectron emission experiments with ECR-driven multi-dipolar negative ion plasma source 

  Laulainen, Janne; Kalvas, Taneli; Koivisto, Hannu; Kronholm, Risto; Tarvainen, Olli; Aleiferis, S.; Svarnas, P. (AIP Publishing, 2017)

  Photoelectron emission measurements have been performed using a 2.45 GHz ECR-driven multi-dipolar plasma source in a low pressure hydrogen discharge. Photoelectron currents induced by light emitted from ECR zone and H− ...

• VUV emission spectroscopy combined with H− density measurements in the ion source Prometheus I 

  Aleiferis, S.; Laulainen, Janne; Svarnas, P.; Tarvainen, Olli; Bacal, M.; Béchu, S. (AIP Publishing, 2017)

  “Prometheus I” is a volume H− negative ion source, driven by a network of dipolar electron cyclotron resonance (ECR; 2.45 GHz) modules. The vacuum-ultraviolet (VUV) emission spectrum of low-temperature hydrogen plasmas may ...

• Hydrogen plasma induced photoelectron emission from metal surfaces 

  Laulainen, Janne (University of Jyväskylä, 2018)

  Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface ...
