Like surfers on monster waves, electrons can ride waves of plasma to very high energies in a very short distance. Scientists have proven that plasma acceleration works.
Physicists have been inventing new types of accelerators to propel charged particles to higher and higher energies for more than 80 years. Today, scientists estimate that more than 17,000 accelerators are in operation around the world—in industry, in hospitals, and at research institutions.
A visitor wandering around SLAC last July would be forgiven for thinking the hot California sun had triggered a mirage. A parking lot at the Stanford Synchrotron Radiation Lightsource had transformed into a glistening lake.
The blue team rounded the bend first—sweaty, jovial, and headed toward the halfway point of the 2.4-mile path circling Brookhaven National Laboratory's Relativistic Heavy Ion Collider. Suddenly, from the other direction, the yellow team emerged.
In August, robots, mummies, and giant jellyfish took over Chicago's Millennium Park. Fortunately, the invasion was peaceful—just part of the fun at the latest LabFest, a kind of pumped-up, hands-on outdoor science fair aimed to engage Chicagoans in the excitement of science.
The Gargamelle collaboration at the European laboratory CERN began operating its bubble chamber in the early 1970s, shooting neutrinos through 12,000 liters of Freon, a heavy liquid.
