Linear Collider Collaboration published Progress Report for the ILC

| 29 October 2015 The ILC Progress Report is a document outlining the technical progress after the publication of the Technical Design Report (TDR) in 2013. It contains the information regarding the progress in civil engineering studies, accelerator hardware design/development updates, accelerator system layout updates, integration/test facilities to be prepared for “hub-laboratory functioning, and updated project implementation plan, and further preparatory work.

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.

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 DESY inForm: Accelerator – stonewashed

| 20 March 2014 Usually it’s basic research – especially for particle accelerators – that pioneers new technology. But in this case the researchers obviously had a little inspirational snoop at Levi’s or any other jeans manufacturer’s. Recently, DESY’s superconducting TESLA cavities have started to be surface-treated with a stonewashing equipment – accelerators stonewashed, so to say. Category: Around the World | Tagged: , , , ,

Strengthening Asian capability in SCRF technology

| 6 March 2014 Sixteen thousand – that’s the number of the superconducting radiofrequency (SCRF) accelerating cavities needed to build the 500-Giga-electronvolt linear collider. The fabrications of these 16 000 cavities will be divided between the three regions of Europe, the Americas, and Asia. This week, encouraging news about SCRF cavity fabrication came from Asia.

‘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.

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.

2013: The year of the snake or the “What if?”

| 24 January 2013 Ewan Paterson, member of the Global Design Effort Executive Committee, weighs the options that new year, new collaboration and TechnicalDesign Report bring. Will 2013 be the year of the "What if"? Category: Director's Corner | Tagged: , , ,
