Ions from a cesium gun are then fired at the target wheel, producing negatively ionized carbon atoms.
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.
There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.
The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.
Detectors at different angles of deflection then count the particles.
At the end of an AMS run, data gathered is not only the number of carbon 14 atoms in the sample but also the quantity of carbon 12 and carbon 13.
There are two accelerator systems commonly used for radiocarbon dating through accelerator mass spectrometry.
One is the cyclotron, and the other is a tandem electrostatic accelerator.
These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.
