  "term": "Pulse width",
  "field": "Chemistry",
  "definition": "The time duration of a primary ion pulse used in techniques like time-of-flight secondary-ion mass spectrometry (ToF-SIMS). This parameter influences the mass resolution of the analysis, as shorter pulses allow for more precise measurement of the secondary ions' flight times. The pulse width is measured at half the maximum intensity of the pulse signal, a value known as the full width at half maximum (FWHM).",
