Charge Exchange Recombination Spectroscopy

Charge Exchange Recombination Spectroscopy (CXRS) is a diagnostic technique used in plasma physics to measure properties like temperature and density of ionized gases in fusion reactors. It works by observing light emitted when high-energy neutral atoms, injected into the plasma, exchange electrons with charged ions. This electron transfer causes the ions to emit specific light signals, which can be analyzed to deduce detailed information about the plasma’s composition and behavior. CXRS provides essential insights for understanding and controlling plasma performance in fusion energy research.
