  "term": "Reflector voltage",
  "field": "Chemistry",
  "definition": "The voltage applied to the mirror electrode of a reflectron mass spectrometer. It is defined by the energy at which ions would just fail to be turned back: an ion leaving the sample with an energy in electronvolts equal to this number in volts sits on the borderline between reflection and passing through. Positive ions are repelled by a positive potential, which is set above the voltage that accelerated them so that they reverse direction inside the mirror.",
