Not all of CERN's accelerators are at the high energy frontier.
Semiconductors are the heart of the computer industry.
They rely on implanting certain materials into other materials. Unstable versions of elements used for such implants make it possible to tell precisely where these elements end up inside semiconductors. This provides an invaluable tool for the computer industry, helping to refine chip manufacturing techniques. In medicine, radio-isotopes are prepared for use in diagnosis and therapy at the Geneva Cantonal Hospital. All elements except the very lightest are cooked up in stars.
