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.
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.

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.
Scientists in the US produced a clutch of antihelium particles, the antimatter equivalents of the helium nucleus, after smashing gold ions together nearly 1bn times at close to the speed of light.
It’s fitting shuttle Endeavour’s final mission is once again to the International Space Station, as its cargo includes a tool to find potential origins of the universe.
Listen to an interview with Brian Foster that aired on 22 March on KPNW, during ALCPG11 in Eugene, Oregon, US, and learn about particle physics, extra dimensions, linear colliders and particle slams.
