On August 7, 2010, photographers had the opportunity to go behind the scenes at these participating laboratories:
CERN in Geneva, Switzerland
Tour description: Un autre regard. The LHC is almost a household name, so CERN decided to show another side of the lab for the particle physics Photowalk. More than 40 photographers glimpsed the future via visits to the laboratory's new linear accelerator, Linac 4, which will soon provide beams to the LHC. The CLIC facility, an innovative technology for accelerating particles to unprecedented energies, was another stop on the tour. Photographers also visited CERN's Computing Centre and the LHC magnet assembly and testing facility.
DESY in Hamburg, Germany
Tour description: Sixty photographers visited an underground detector hall where the HERA B detector used to reside, where they saw parts of the old detector and where new detectors are being built and tested. Other 'photo stations' included: the HERA accelerator tunnel, an experiment control room and other test areas for the laboratory's detectors and accelerators.
Fermilab in Illinois, USA
Tour description: Fifty photographers got a full morning of behind-the-scenes access to places not normally open to the public. They went underground into one of the accelerator tunnels, explored the antimatter factory and photographed some of the physics experimental facilities around the site.
KEK in Tsukuba, Japan
Tour description: Forty photographers were guided through the following research areas: Belle Linear Accelerator, Photon Factory, Advanced Test Facility, Superconducting RF Test Facility and the Cockcroft-Walton Accelerator.
TRIUMF in Vancouver, Canada
Tour description: Forty photographers visited the world's largest cyclotron (built and operating at TRIUMF), the medical-isotope production area and Canada's second PET scanner, and toured two experimental halls where scientists use beams of exotic isotopes to study the structure of nuclei and the origins of the chemical elements on Earth.
