BELLA: Building a Table-Top Accelerator

BELLA: Accelerating Science by Accelerating Electrons: Berkeley Lab scientists stunned the world in 2006 when they proved they could accelerate electrons to very high energies (1 GeV, or a billion electron volts) in a distance of centimeters rather than hundreds of meters. Using the same concepts, those scientists plan to take the project to the […]

Large Hadron Collider: Cold and Ready for Physics

CERN: LHC completes the circle. ‘At a brief ceremony deep under the French countryside today, CERN Director General Robert Aymar sealed the last interconnect between the main magnet systems in the Large Hadron Collider (LHC). This is the latest milestone in commissioning the LHC, the world’s most powerful particle accelerator. The LHC’s superconducting main magnets […]

Compact Muon Solenoid (CMS)

Milestone for giant physics lab. ‘Construction on a giant underground laboratory that will help take physics into a new era is reaching a major milestone. At 0500 GMT, a crane began to lower 2,000 tonnes of machinery into a man-made cavern 100m below ground. The machinery is part of the Compact Muon Solenoid (CMS), one […]

Using Bosons to Test String Theory

Theoretical Physicists Develop Test for String Theory. ‘For decades, many scientists have criticized string theory, pointing out that it does not make predictions by which it can be tested. Now, researchers at Carnegie Mellon University; the University of California, San Diego; and The University of Texas at Austin have developed a test of string theory. […]
