From Fermilab Today: Fermilab’s new cavity temperature mapping system commissioned

| 26 July 2012 Fermilab scientists have a new diagnostic tool that could lead to far more efficient accelerator cavities. The temperature mapping system, fitted with 576 sensors, reads the temperature of every square centimetre of cavity surface and might thus help scientists get to the bottom of the problem of why superconducting cavities dissipate much more energy than theory predicts.

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.
