Barbara Warmbein | 3 July 2014Cornell 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.

5 June 2014Thanks to science, we get more for less. We get more features on a newer car model, more data and information stored on a computer, and all for the same or lowered cost. That same principle applies to accelerator R&D, where improving the performance and lowering the cost can help open doors to new ideas. The Department of Energy recently named Fermilab physicist and 2013 Peoples Fellow Anna Grassellino as a recipient of the prestigious Early Career Research Award for her work to develop particle accelerator cavities that have improved performance and are less expensive to operate.

19 December 2013CRISP, the "Cluster of Research Infrastructures for Synergies in Physics" is a European-funded project and one of its objectives is to upgrade and harmonise the SRF Accelerator Structures for ESS, ILC, LHC upgrade and the European XFEL. The activity supports an optimised surface treatment, the application of advanced test and preparation infrastructure as well as state-of-the-art diagnostics tools. Significant focus is laid on the knowledge transfer between ESS, CERN and DESY. Read more in Accelerating News Winter 2013 issue

Barry Barish | 21 November 2012One of the most important goals of the Global Design Effort has been to demonstrate that high-gradient cavities can be reliably produced in industry. We established two gradient goals: to produce cavities qualified at 35 Megavolts per metre (MV/m) in vertical tests and to demonstrate that an average gradient of 31.5 MV/m is achievable for ILC cryomodules. Furthermore, we set a goal of producing these high-gradient cavities in industry with 50% yield by 2010 and 90% yield by the end of 2012. We have recently achieved these ambitious goals!
