CTF5 electron impact ion source


  • small angled reflectron with two-stage ion mirror
  • electron impact ionisation
  • (folded) field-free drift space with 395 mm overall length
  • extremely high sweep rates up to 170 kHz due to the short time-of-flight of the ions
  • resolution M/ delta M > 1000 (mass 130)
  • 8 keV transmission energy of the ions in the spectrometer, resulting in short flight times
  • 25 mm two-stage mcp detector with extended dynamic range


  • detector behind the ion reflector
