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: , , , , , , , ,

Second sound sounds promising

| 26 June 2008 “Our superconducting technology group here at Cornell is doing some very fundamental R&D,” says Hasan Padamsee, physics professor at Cornell university and expert in superconducting rf technology. “Note that the stress is on the fun in fundamentals.” Students are even allowed to drill holes into cavity prototypes in order to find out what makes certain areas in the material behave differently from others. A new mapping technique, invented by Cornell's Don Hartill, Zach Conway and Eric Smith, could make it possible to locate quenches during cavity tests with just eight (instead of up to 180) thermometers.
