Building the parts for the Large Hadron Collider has presented challenges but taught many lessons for both particle physics laboratories and their industry partners.
The United States has contributed the energy and expertise of hundreds of scientists and engineers, and more than half a billion dollars to the construction of the LHC particle collider and two of its experiments at the European laboratory CERN.
A proton travels around a 27-kilometer ring at nearly the speed of light. Along with a bunch of other protons, it passes through the hearts of each of a series of detectors more than ten thousand times per second. Then, on one pass, it slams into a proton coming from the other direction.
The worldwide particle physics community is about to sail on a voyage into a New World of discovery. The Large Hadron Collider, a multi-billion-dollar particle collider that will begin operations in Europe in 2007, will take us into new realms of energy, space, time, and symmetry.
Experimental clues have yet to produce a 'tsunami moment' that provides a glimpse beyond the equations of particle physics formulated in the 1970s. But physicists are hoping for something bizarre.
We are constantly being told that we live in a competitive world in which innovation is the main driver towards growth and prosperity. What is the place in such a world for fundamental science, whose short-term contribution to society is knowledge without any immediate application?
The start-up of the Large Hadron Collider at CERN next year promises to be the most exciting moment in particle physics for many years. It is also an opportunity to revitalize the publics interest in the field.
The Positron Electron Project (PEP) collider at the Stanford Linear Accelerator Center produced its first collisions in 1979. All sorts of particles burst out, including the tau lepton, an ephemeral cousin of the electron.
Have you ever tossed a ball at a wall, playing a game of one-man catch? As you tossed that ball again and again and again, have you ever thought about the chance that it could go right through the wall? According to quantum mechanics, this is a real possibility.
Street banners honoring nine of Berkeley Lab's Nobel Prize winners, originally installed along Telegraph Avenue in 2003, have been mounted on poles on Cyclotron Road leading to Berkeley Lab in honor of its 75th anniversary.
Mesons. Bosons. Pions. Muons. Asparagus. Yes, asparagus. Physicists have spare time, too, and a few of them spend it in Fermilab's Garden Club, with roots almost as old as the lab itself.
Welcome to SLAC's End Station B, where work on the International Linear Collider (ILC) will help shape the future of particle physics–although some inhabitants don't seem to give a hoot.
After undergoing a buffered chemical polishing (BCP) treatment at Cornell University, the first US-processed and tested International Linear Collider superconducting cavity achieved a milestone accelerating gradient of 26 MV/m (megavolts per meter)–surpassing the first gradient goal (25 MV/m).
Over a half-eaten burrito or a bowl of spaghetti, Sam Ehrenstein ponders the unanswered questions of fundamental physics. Yet Sam is no experimental physicist or postdoc brooding over his data. Not yet, anyway.
Along the Loop Road at Stanford Linear Accelerator Center, the roar of falling water and a refreshing mist filled the air after six solid weeks of California rain. But the water cascading down the inside of Campus Cooling Tower 101, and landing in a frothy pool, is hardly scenic.
