Step inside the incredibly narrow tunnel at the heart of a city-block sized particle accelerator, and witness what an electron sees as it races through the Australian Synchrotron. This rare glimpse captures the interior of a Cryogenic Undulator which is about to be installed into the main ring where it will be used as a lightsource for the Nanoprobe Beamline.

This astonishingly complex (and expensive) scientific instrument behaves much like a musical instrument, although its vibrations are closer to the speed of light than the speed of sound! 

Electrons are fired down this shaft in tight, synchronized pulses. The intensely powerful
magnets above and below cause the particles to undulate ever so slightly, much like the
string of a fine cello. That tiny movement sets off a cascade of electromagnetic waves that unleash an incredibly intense laser-like beam of light (x-ray synchrotron radiation) that scientists use to probe the hidden structures of our everyday world.

Photographed using a medical laparoscope adapted to a Lumix camera, this image reveals the intricate world of high-energy physics. Available as a limited-edition print, this is a rare opportunity to own a piece of cutting-edge science, frozen in time before it vanishes from sight.
