Tiny double accelerator recycles energy

A team of DESY scientists has built a miniature double particle accelerator that can recycle some of the laser energy fed into the system to boost the energy of the accelerated electrons a second time. The device uses narrowband ...

The power of attraction: Magnets in particle accelerators

In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what effect an electric current ...

Scientists create the first diamond X-ray micro lens

After fourth-generation synchrotrons were invented (these are particle accelerators, which are, in fact, giant research facilities), there was an urgent need for a fundamentally new optics that could withstand high temperatures ...

Researchers build a particle accelerator that fits on a chip

On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts ...

Colliding molecules and antiparticles

Antiparticles—subatomic particles that have exactly opposite properties to those that make up everyday matter—may seem like a concept out of science fiction, but they are real, and the study of matter-antimatter interactions ...

Fusion by strong lasers

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires ...
