11 February 2013 – Last September, hundreds of amateur and professional photographers streamed into particle physics laboratories around the world to produce thousands of photographs of state-of-the-art equipment, laboratories and people, in all their beauty and complexity. Now, the citizens of the world are invited to vote for their three favorites as part of the "people's choice" global photowalk competition.
In total, last year's Particle Physics Photowalk brought nearly 400 photographers to 10 leading physics laboratories. After a short pause for downloading, processing and, in some cases, actual developing, the photographers submitted their best photos to a series of local competitions. From these competitions emerged the top 10 photos from each participating country.
View the 40 finalists and cast your vote at http://www.interactions.org/photowalk/vote.
In addition to the people's choice winner, a panel of international judges will select a second global winner. Both winning photos will be announced in March and will be displayed in laboratory exhibits around the world. They will also appear in the particle physics publications symmetry and the CERN Courier.
Photographers joined the Particle Physics Photowalk at these participating laboratories:
Brookhaven National Laboratory in New York, USA
Chilbolton Observatory in Hampshire, UK
Daresbury Laboratory in Cheshire, UK
Fermilab in Illinois, USA
Frascati National Laboratory in Frascati, Italy
Gran Sasso National Laboratory in Gran Sasso, Italy
Rutherford Appleton Laboratory in Oxfordshire, UK
Southern National Laboratory in Catania, Italy
TRIUMF in Vancouver, Canada
United Kingdom Astronomy Technology Centre in Edinburgh, UK
In Canada, participants visited and photographed major experimental facilities not usually open to the public including TRIUMF's rare-isotope accelerators, some of the most powerful in the world.
In the United States, highlights included Fermilab's muon storage ring, formerly the lab's antimatter source, and the Collider Detector at Fermilab, a 4,500-ton detector that sits four stories tall and is composed of more than one million individual detector elements. At Brookhaven National Laboratory, visitors were able to explore the Relativistic Heavy Ion Collider, the only particle collider currently operating in the United States, and the National Synchrotron Light Source, which provides intense, focused light for research as diverse as better batteries, new high-performance materials and more effective drug treatments.
In Italy, photographers descended into the largest underground laboratory in the world, Gran Sasso National Laboratory, to photograph the many experiments protected beneath 1400 meters of rock. On the surface, participants explored the many accelerators and detectors at Frascati National Laboratory and Southern National Laboratory.
In the United Kingdom, participants toured Chilbolton Observatory, with its 25-meter antenna and millimetre wave laboratory; Daresbury Laboratory's Cockcroft Institute and the Engineering Technology Centre, where machinery is developed for some of the world's most advanced scientific equipment; Rutherford Appleton Laboratory's Ion Source Laboratory, space assembly integration and verification facility, and robotics trial area; and the UK Astronomy Technology Centre's 36-inch telescope and electronics and materials laboratories.
