  "term": "Primary electrons",
  "field": "Chemistry",
  "definition": "Electrons originating directly from an electron source, such as an electron gun in an electron microscope or a cathode ray tube. These electrons possess the initial kinetic energy imparted by the source before any interactions with a sample. Their energy typically ranges from a few electronvolts to several hundred kiloelectronvolts.",
