SCRF R&D for ILC upgrade – tin for the future?

Cornell experiments with Nb3Sn for cavities

by Barbara Warmbein

Cornell is working on a technology that could make superconducting cavities even more efficient: niobium alloyed with tin. Currently in single-cell research stage, tests show promising results, especially for the quality factor Q. Cornell university has always been a big player in the development of superconducting radio frequency technology SCRF, the technology chosen for the ILC. Even though research into Nb3Sn-cavities is not advanced enough to replace conventional cavities just yet, it might play a big role in future upgrades of the ILC – and in many other accelerators for all kinds of purposes the nearer future.

From CERN: CERN announces LHC restart schedule

The Large Hadron Collider (LHC), the largest and most powerful particle accelerator in the world, has started to get ready for its second three-year run. Cool down of the vast machine has already begun in preparation for research to resume early in 2015 following a long technical stop to prepare the machine for running at almost double the energy of run 1. The last LHC magnet interconnection was closed on 18 June 2014 and one sector of 1/8 of the machine has already been cooled to operating temperature. The accelerator chain that supplies the LHC’s particle beams is currently starting up, with beam in the proton synchrotron accelerator last Wednesday for the first time since 2012.
