Solid angle of analyser

{
  "id": "MLC-T-CHM-010989",
  "term": "Solid angle of analyser",
  "field": "Chemistry",
  "definition": "The angular range over which an electron or ion energy analyzer collects particles emitted from a sample surface. It is a measure of the analyzer's collection efficiency and is expressed in steradians. A larger solid angle generally leads to higher signal intensity but can sometimes reduce energy or angular resolution in surface analysis techniques.",
