Impersonating bulk niobium

| 5 May 2011 Anything bulk niobium can do, thin films can do better. At least, that’s the hope of Jefferson Laboratory scientists, who are currently exploring a method that would allow them to create customisable thin niobium films. Category: Around the World | Tagged: , , , , , ,

A conformal approach to cavity coating

| 28 April 2011 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. Category: Around the World | Tagged: , , , , ,

The sound of accelerator cavities

| 21 April 2011 Elegant and inexpensive, the second-sound detection system developed at Cornell University helps scientists triangulate the location of hard-to-see accelerator cavity flaws. Helium helps. Category: Feature | Tagged: , , , , , , , ,

A robot to watch out for defects

| 14 April 2011 A small group of young researchers at DESY, Germany, is working on a robot that could drastically reduce the time it takes to optically inspect a cavity. Their work covers everything from the pure mechanics of the workbench and fine-tuned motors for moving the heavy parts to developing sophisticated methods of automatically analysing the pictures. Cavities might eventually pass the check in two hours instead of the one-and-a-half days it takes today. Category: Around the World | Tagged: , , , , ,
