To investigate the scrape-off layer, the spectrometer has been made sensitive to low-energy hydrogen atoms. This has been done by converting the hydrogen atoms into more easily detectable negative hydrogen ions on a cesiated monocrystalline tungsten surface. This detection technique enables examination of the neutral particle flux in a large energy range (5-2000 eV). Typical examples of time-of-flight spectra recorded during TORTUR discharges will be shown.}, year = {1992}, journal = {Review of Scientific Instruments}, volume = {63}, number = {4}, pages = {2223-2231}, month = {Apr}, isbn = {0034-6748}, doi = {10.1063/1.1143143}, language = {eng}, }
