Daisy Yuhas | 4 October 2012What 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.

Daisy Yuhas | 23 August 2012Physicists 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.

Image: DESY | 7 June 2012Some 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.

Barbara Warmbein | 24 May 2012There’s no doubt that the life of a cavity is exciting – lots of power, whizzing particles, superconductivity, the lot. How does it get there, what are the stations of its life? A new photo series is in production that follows a cavity from niobium ingot to cryomodule, and an exhibition of these images opens next week at DESY in Germany.

Leah Hesla | 1 September 2011Accelerator cavities have their faults, and some pits and cracks hide deep in the walls or in out-of-the-way places where they aren’t easily found. Accelerator researchers help improve flawed cavities by taking their fault-finding missions beneath the cavity surface with X-ray computed tomography.

Akira Yamamoto | 26 May 2011As part of Technical Design Phase 2, the Global Design Effort has been working towards more realistic and cost-effective industrialisation models for the production of superconducting radiofrequency cavities and cryomodules, as these are primary cost drivers in the ILC construction estimate. To that end, they have been organising a series of visit to cavity and material manufacturers and workshops. The next one is in July 2011 in Chicago, US.
