particle accelerator

They are created by nuclear fusion reactions in the sun, radioactive decay in nuclear reactors or the Earth's crust or in particle accelerator labs.

In order to overcome these difficulties, the research team used state-of-the-art technology: the Synchrotron particle accelerator in Grenoble.

It is therefore impossible to determine the point of origin of such charged particles in space, although their detection on Earth is a clear indicator that there are powerful cosmic-ray particle accelerators in its vicinity.

The particle accelerator, built at a cost of $10bn, was the most powerful yet.

The fraction of radiocarbon in pure carbon is measured using a particle accelerator.
