Successful test of new US magnet puts Large Hadron Collider on track for major upgrade

The U.S. LHC Accelerator Research Program (LARP) has successfully tested a powerful superconducting quadrupole magnet that will play a key role in developing a new beam focusing system for CERN's Large Hadron Collider (LHC). This advanced system, together with other major upgrades to be implemented over the next decade, will allow the LHC to produce 10 times more high-energy collisions than it was originally designed for.

NIST shows how to make a compact frequency comb in minutes

Laser frequency combs-high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy-are not only getting smaller but also much easier to make.

Technology developed to control light scattering using holography

Recently, a popular article demonstrated that opaque glass becomes transparent as transparent tape is applied to the glass. The scientific principle is that light was less scattered as the rough surface of the opaque glass is filled by transparent tape. Professor Yong Keun Park from KAIST's Department of Physics, in a joint research with MIT Spectroscopy Lab, has developed the technology to easily control light scattering using holography. Their results are published on Nature's Scientific Reports May 29th online edition.

Most accurate measurement of Boltzmann constant yet

Scientists at the UK's National Physical Laboratory (NPL) have performed the most accurate measurement yet of the Boltzmann constant.
