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.

Cavity gradient

| 10 January 2013 What is an accelerating gradient? How do particles get accelerated, and how much? LCpedia explains. Category: LCpedia | Tagged: , , , ,


| 4 October 2012 What is a quench? Everything has a limit—superconducting cavities are no exception. Physicists put voltage in their superconducting cavities to boost the energy of particles. But it’s possible to ask for too much from a cavity. When this happens, the cavity fails: the superconducting material becomes normal-conducting, the voltage collapses and the energy escapes. This is called a quench. Category: LCpedia | Tagged: , ,

Cavities at your fingertips

| 30 August 2012 Are you giving a talk about the ILC, cavities, S(C)RF or linac design and are looking for images that haven't been used a million times? A 17-image series following the life of a cavity from niobium ingot to finished cryomodule is now available on the Interactions image bank. Category: Image of the week | Tagged: , ,

Q – cavity quality factor

| 23 August 2012 Physicists need to understand each accelerator cavity individually before assembling a collider. One of the cavity characteristics physicists measure is called the cavity quality factor, Q factor for short. The LCpedia series continues. Category: LCpedia | Tagged: , ,

Cavities in the spotlight

| 7 June 2012 Some 100 cavity and photo enthusiasts came to DESY last Wednesday to hear Karsten Büßer talk about "Cool Runnings" and see the picture story of cavities in the making by science photographer Heiner Müller-Elsner. The exhibition will be on show at DESY for a few more weeks. Read more here. Category: Image of the week | Tagged: , , , ,
