1. adjusting CRYEBIS for high (Xe³⁵⁺) &low (S⁺) charge states:
   • changing seed gas supply,
   • changing solenoid field,
   • tuning electron beam transmission,
   • optimizing desired charge state,
   • measuring charge state distribution,
   • tuning slow and fast expulsions
2. accelerating S⁸⁺ ions to 50 keV/q
   • changing platform high voltage supply,
   • detecting ions at switching magnet with BPM and FC
   • optimizing transport with platform elements,
   • identifying charge states with diagnostics
3. transporting 50 kV S⁸⁺ ions to a target in a beam line
   • selecting proper supplies for switching magnet and lenses
   • finding ions with multiplier, slits, or Faraday cup,
   • determining peak count rates of detected particles
4. decelerating S⁸⁺ to 1 keV/q, and repeating 2)
