Of cavity performance, tiny beams and official roles: progress in a maturing project

| 5 June 2014 Regional Director Akira Yamamoto reports from the Americas Workshop on Linear Colliders (AWLC) 2014 held last month at Fermilab, US. A new official structure gives weight to contributions from scientists who used to juggle linear collider work and their projects “at home”, and in general he observes that big progress is common when a technology hasn’t reached a certain stage of maturity, but once it has, the steps become smaller, but almost more important.

From Fermilab Today: First cavity in Cryomodule 2 achieves goal gradient

9 January 2014 On 20 December, members of the Accelerator Division SRF Electron Linac Department and the Technical Division SRF Development Department successfully brought the first accelerating cavity in Cryomodule 2 to a gradient of 31.5 megavolts per meter, the gradient required for the proposed International Linear Collider. The achievement demonstrates the cavity's successful integration into the cryomodule. Category: Feature | Tagged: , , ,

‘A little dirt never hurt’

| 21 November 2013 After years of pursuing purity in the niobium material used to make superconducting radiofrequency cavities, a Fermilab team led by Anna Grassellino has found that baking cavities to introduce certain impurities may improve the cavity performance. The new method may provide a way for ILC-type cavities to reach up to three times higher quality factors—enabling more cost-effective accelerators. Category: Around the World | Tagged: , , , , , , ,

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.

Take two for cryomodule 2

| 11 July 2013 With the repair and reinstallation of the cryomodule known as CM2, Fermilab researchers are back on the road towards achieving the International Linear Collider’s R&D “S1” goal: operating a cryomodule at ILC gradient specifications.

Moving from emotions to negotiations

| 27 June 2013 Physics isn’t usually associated with big emotions, and in the everyday life at the labs this is probably true. However, our field has recently had many momentous events, and the excitement these have caused have made particle physics one of the most popular science topics in the world. Let’s use this momentum to get ahead in our plan to build the ILC – maybe in stages and in Japan? Category: Director's Corner | Tagged: , , ,

Press release: Next-generation particle accelerator is ready for construction

13 June 2013 Tokyo, Geneva, Chicago – 12 June 2013. A five-volume report containing the blueprint for a future particle physics project, the International Linear Collider (ILC), was published today. In three consecutive ceremonies in Asia, Europe and the Americas, the authors of the Technical Design Report for the International Linear Collider, a next-generation particle collider to complement and advance beyond the physics of the Large Hadron Collider at CERN, officially handed the report over to the international oversight board for projects in particle physics, the International Committee for Future Accelerators ICFA. The Technical Design Report presents the latest, most technologically advanced and most thoroughly scrutinised design for the ILC. Category: Feature | Tagged: , , , , , ,

Korea-US Collaboration Center for Accelerator Science opens at Fermilab

From Fermilab Today: Fermilab’s new cavity temperature mapping system commissioned

| 26 July 2012 Fermilab scientists have a new diagnostic tool that could lead to far more efficient accelerator cavities. The temperature mapping system, fitted with 576 sensors, reads the temperature of every square centimetre of cavity surface and might thus help scientists get to the bottom of the problem of why superconducting cavities dissipate much more energy than theory predicts.
