  Diamond Light Source - Wikipedia, the free encyclopedia
Diamond Light Source is a synchrotron research facility located on the Rutherford Appleton Laboratory in Oxfordshire, England.
Diamond will emit synchrotron light or electromagnetic radiation, at wavelengths from X-rays to far infrared that will be used to study the structure and behaviour of many different types of matter.
Diamond is housed in a silver toroidal building which covers the area of 5 football pitches, containing the synchrotron ring and a number of research beamlines where the interaction of radiation with matter will provide evidence for the properties of many materials.

 Spencer & Spencer | Diamond Cut
Cut is critical to the beauty of a diamond not only because it affects the interaction between a diamond and the light around it, but because the way a diamond is cut can sometimes affect its color and clarity.
Since a round diamond is symmetrical and capable of reflecting nearly all the light that enters, it is referred to as a “round brilliant” because it is the most brilliant of all diamond shapes.
A diamond’s finish is the quality of its polish and symmetry as well as the condition of its girdle and the precision of its cut.

 SRS ANNUAL REPORT 2001-2002
Diamond is scheduled to operate in late 2006 with the phase 1 funding providing for the building, the 3GeV accelerator and an initial set of 7 beamlines with associated experimental facilities.
This consists of a source of light within the accelerator (in this case an undulator), the optical system for conditioning the light (focusing and wavelength selection) and the experimental apparatus itself, often contained in a shielding 'hutch' if X-rays are being used.
Diamond is a low emittance source which means that the light has small spatial dimensions and low divergence.

 So, You're Thinking About Buying A Diamond…
As the rough diamond is born from the ground dull and lifeless, so the spiritual man begins his journey in the world with his true luminosity hidden.
When diamond graders thinks of shape, they consider both the shape of the stone and the way each individual facet or flat polished surface is placed on the diamond.
The diamond, the light source or the viewer must be in motion for scintillation to happen.

 symmetry - May 2005 - Springtime at Daresbury
It was home to the world's first dedicated synchrotron light source, the SRS, which began operating in 1980 and has chugged steadily along, with here and there an upgrade, for the last 25 years.
In the 1990s, Daresbury scientists began work on the design for a proposed new third-generation synchrotron light source, Diamond, in the confident expectation that, if approved, it would be built at Daresbury, to replace the aging SRS and ensure a predictable light-source future for the laboratory.
In fact, the decision to build Diamond at Rutherford was the spark for Daresbury's reinvention of itself as a laboratory at the forefront of accelerator technology, said Daresbury accelerator physicist Susan Smith.

 Evaluating a Diamond: Cut: One of the 4 C's: Article from The Diamond Experts: Dutton's Diamonds
Here we focus on the modern round brilliant cut diamond because it is the most popular shape sold and it produces the best light return, in the form of brilliance, dispersion and scintillation, to the eye.
In diamonds with too steep a crown angle (>38deg.), exiting light is directed out to the side where it isn't visible, or it can be reflected back into the stone.
All of the diamonds sold by Dutton's Diamonds are graded by AGS or GIA, and in the latter case most have accompanying Sarin analyses.

The Diamond Light Source synchrotron is a new science facility - the largest to be built in the UK for over 30 years - housed in a doughnut-shaped building over half a kilometre in circumference, covering the size of 5 football pitches.
The light is directed to the beamlines and accelerated using bending magnets located at the insertion points around the storage ring.
Once the light enters the beamline, it is guided, intensified or deintesified using series of slits, lenses and crystals; the angles and positions of which are dictated using electric motors whose motion commands are generated by Delta Tau controls.

 Controlling Beams of Light on Design News - 7/18/2005 - Design News - CA625882   (Site not responding. Last check: 2007-10-21)
Motion control for a synchrotron, the source of the brightest light available today, is a critical issue because it involves a variety of motor technologies, magnets, and optics directing electrons around a circle a half kilometer in diameter and capturing photons of light as the electrons turn.
A synchrotron is a particle accelerator that produces very intense and tightly focused light by accelerating electrons close to the speed of light and bending the resulting beam of electrons with magnets.
In the Diamond Light synchrotron application—where tight coordination between axes is required—this motion control approach provides required synchronization mechanisms to insure precise coordination.
