Within the machine, which is sometimes described as a "super microscope", electrons are accelerated into a thin, doughnut-shaped vacuum chamber, which measures 562.6m (1,846ft) in circumference.Within the machine, which is sometimes described as a "super microscope", electrons are accelerated into a thin, doughnut-shaped vacuum chamber, which measures 562.6m (1,846ft) in circumference.
As the particles whizz around and around, almost reaching the speed of light, they lose energy in the form of synchrotron light.As the particles whizz around and around, almost reaching the speed of light, they lose energy in the form of synchrotron light.

"The problem is, to understand them, we need to understand the magnetic structure at nanometre scales. The beamline we have been using for the last six days has a special microscope that can image magnetic structures at these very small scales.""The problem is, to understand them, we need to understand the magnetic structure at nanometre scales.

The Diamond synchrotron will be replacing the Synchrotron Radiation Source (SRS) in Daresbury, Cheshire. The SRS was the world's first dedicated synchrotron but is due to close at the end of 2008.
