Bump or no bump

| 11 August 2016 High Energy Physics (HEP) has always been a field with great discoveries and the field seems to be ‘storming’ forward as some attendees of this ICHEP declared. Not only new LHC results were the center point of this conference but also the discovery of gravitational waves, new neutrino measurements and of course future facilities like the ILC and CLIC.

From metal sheet to particle accelerator (part 3 of 3)

| 12 May 2016 If you're an electron, a ride in a cavity is pretty much the coolest thing that can happen to you. If you're an accelerator and you need huge numbers of cavities you better make sure they're all of outstanding quality – which is what the X-ray free-electron laser European XFEL under construction in Hamburg has just finished. In a series first published in DESY inForm, we look at how a niobium sheet turns into a curvy beauty. Part three describes how they make their way from test benches into the cryomodules and, finally, into the tunnel. Category: Around the World | Tagged: , , , , , , ,

Superconducting cavities are a ‘hot’ topic

| 15 October 2015 From 14 to 18 September 334 physicists, engineers and technicians from all around the world made their way to Whistler, Canada, for the 17th International Conference on Superconducting Radiofrequency (SRF). The conference takes place every two years and shines a light upon all new developments in the different fields of superconducting cavities. It is the leading conference in this field of physics and discusses the actual state of the art of this technology. And right now it is a topic that progresses very fast.

SRF Technology getting ready for the ILC: A Report from Whistler

| 1 October 2015 Reporting almost live from Whistler, Canada, Akira Yamamoto says progress is impressive. The conference SRF 2015 covered the latest advances in the science, technology, and applications of superconducting RF, including leading SRF accelerator projects, such as European XFEL, the European Spallation Source, FRIB, and the LCLS-II project.

No more HF?

| 26 September 2013 In June, Fermilab researchers finished successfully processing and testing the second single-cell, ILC-type cavity that was electropolished with a new technique. The water-based process, which doesn’t require the use of strong acids as the standard technique does, was developed to be more environmentally and worker-friendly.

Hydrides: the nemesis of high-quality SRF cavities?

| 25 July 2013 Hydrogen has long been known as a possible enemy of superconducting radiofrequency (SRF) cavities - like those needed for the ILC - thanks to its potential to form non-superconducting hydrides that limit cavity quality factor (Q) and gradient. Researchers at Fermilab have made further progress in understanding the full physics behind hydrogen involvement, which is an important step towards improvements in cavity processing.
