A conformal approach to cavity coating

Argonne scientists give metals a healthy superconducting coat, one atomic layer at a time.

by Leah Hesla

Argonne researchers are working to coat accelerator cavities with perfectly uniform atomic layers of niobium. The thin film technology could help slash production and operation costs in particle accelerator programmes while boosting accelerator performance.

from CERN: LHC sets world record beam intensity

Geneva, 22 April 2011. Around midnight this night CERN’s Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 × 1032 cm-2s-1. This exceeds the previous world record of 4.024 × 1032 cm-2s-1, which was set by the US Fermi National Accelerator Laboratory’s Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

    World’s biggest antimatter nucleus produced at Brookhaven
    The RHIC is back in the news today, as one of its detectors has found evidence of the production of anti-helium-4 nuclei. The rates at which these particles were produced, however, suggests that we won’t be seeing anti-nuclei of any greater complexity anytime soon.
