AMS has also contributed greatly to environmental and atmospheric studies by providing information regarding particle composition and origin.

In the biochemical field, synthesized C labeled compounds can be administered as a tracer dose for in-vivo human metabolic and drug studies which require AMS analysis of graphitized biological samples.

“Just the fact that AMS requires only a tiny sample has opened up whole new fields,” says John Southon, co-founder of the AMS facility at the University of California, Irvine.

In 1939, UC Berkeley scientists Luis Alvarez and Robert Cornog were the first to use AMS in the detection of Now, over 70 years later, cyclotrons have been replaced by an accelerator type with greater energy stability: the tandem electrostatic accelerator.An electrostatic accelerator works by accellerating particles though a magnetic field generated by high voltages using a mechanic transport system that continuously transports charges from ground to the insulated high-voltage terminal.All tandem accelerators with a maximum terminal voltage above 5 MV use such a mechanical system.AMS is a highly sensitive method for isotopic analysis that has numerous key applications that are only growing with advances in technology.

High costs and technical complexities that arise with the use of a particle accelerator are the only limits to the widespread use of AMS.

Cs It is important to have a beam of negative ions entering the accelerator because the negative ions are attacted to the high -voltage terminal which results in their net acceleration. In sequential injection, typical injection repetition rates are 10 sec C analysis.
