The electrostatic analyzer is a pair of metal plates at high voltage that deflects the beam to the left by 20 degrees.This selects particles based on their energy and thus removes the ions that happen to receive the wrong energy from the accelerator.The gas ionization detector counts ions one at a time as they come down the beamline.The ions are slowed down and come to rest in propane gas.

AMS uses a particle accelerator in conjunction with ion sources, large magnets, and detectors to separate out interferences and count single atoms in the presence of 1x10 (a thousand million million) stable atoms.Think of it as a bridge that spans the inside of a large pressure vessel containing CO insulating gas at a pressure of over 10 atmospheres.The bridge holds two long vacuum tubes with many glass (electrically insulating) sections.(Highly charged molecules are unstable since they are missing the electrons that bind the atoms together).Isotope ratios are measured by alternately selecting the stable and radioisotopes with the injector and analyzing magnets.

The mass of these ions is then measured by the application of magnetic and electric fields.
