The bridge holds two long vacuum tubes with many glass (electrically insulating) sections.

The center of the accelerator, called the terminal, is charged to a voltage of up to 10 million volts by two rotating chains.

In living organisms, which are always taking in carbon, the levels of carbon 14 likewise stay constant.

But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay.

They are used for a wide variety of dating and tracing applications in the geological and planetary sciences, archaeology, and biomedicine.

The following is a brief description of each element of the AMS system.

The negative ions traveling down the beam tube are attracted (accelerated) towards the positive terminal.

There are still lots of molecules and isobars (isotopes of neighboring elements having the same mass) that must be removed by more magnets after the accelerator.Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.Libby thus reasoned that by measuring carbon 14 levels in the remains of an organism that died long ago, one could estimate the time of its death.So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.The procedure of radiocarbon dating can be used for remains that are up to 50,000 years old.
