This may be a solid-state detector or a device based on the gridded ionisation chamber.The latter type of detector can measure both the total energy of the incoming ion, and also the rate at which it slows down as it passes through the gas-filled detector.Additionally, the impact strips off several of the ion's electrons, converting it into a positively charged ion.In the second half of the accelerator, the now positively charged ion is accelerated away from the highly positive centre of the electrostatic accelerator which previously attracted the negative ion.Accelerator mass spectrometry (AMS) differs from other forms of mass spectrometry in that it accelerates ions to extraordinarily high kinetic energies before mass analysis.

In a second stage of mass spectrometer, the fragments from the molecules are separated from the ions of interest.Sample selection and analysis is carried out in close contact with project scientists. Established analytical procedures for radiocarbon dating are carefully applied to every sample the laboratory processes. New methods are developed and tested as necessary to meet specific dating needs and to improve the overall accuracy and precision of the lab. Radiocarbon dating by accelerator mass spectrometry (AMS) is an important analytical method utilized in climate change, land use change, ecosystems and natural hazards research.

This is a large nuclear particle accelerator based on the principle of a Tandem van de Graaff Accelerator operating at 0.2 to many million volts with two stages operating in tandem to accelerate the particles.
