  "term": "Thermal column",
  "field": "Chemistry",
  "definition": "A section of a nuclear reactor designed to extract a beam of thermal neutrons for experimental purposes. It consists of a large block of a moderating material, such as graphite, placed adjacent to the reactor core. This arrangement slows down fast neutrons to thermal energies, providing a high flux of low-energy neutrons.",
