STF-2 Beam Operation Demonstrates ILC Specifications

30 May 2019 KEK’s Superconducting RF Test Facility (STF) operated the first beams during February and March 2019 and demonstrated results that satisfy the specifications for the International Linear Collider (ILC). 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.

From the world to America: seeding superconducting accelerator technology through the ILC

| 2 October 2014 The superconducting technology at the heart of the ILC is one of the outstanding innovations of the machine’s design. The new kid on the block, SLAC National Accelerator Laboratory’s light source LCLS II, owes much to the ILC's advances in superconducting radio-frequency technology.

‘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: , , , , , , ,

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.

Triple milestone for Cornell’s ERL programme

| 29 March 2012 Researchers at Cornell University's Energy Recovery Linac programme recently achieved three milestones in two months. One of them could lead to more reliable superconducting accelerator cavities. Category: Around the World | Tagged: , , , , , , , ,

ILC technology in the Guinness Book of World Records!

2 February 2012 The world’s fastest (and shortest) movie has superconducting radiofrequency technology to thank for its entry into the Guinness Book of World Records. Shot at DESY’s FLASH X-ray laser, which accelerates electrons in much the same way as the ILC will, it shows a micro model of the German Brandenburg Gate at an interval of a mere 50 femtoseconds between two frames.

The capability for producing niobium sheets

| 26 January 2012 Japanese company Tokyo Denkai is boosting high-purity niobium production and processing with some new equipment and a better-outfitted shop. Should the ILC be built, the company will be able to handle the large order of niobium needed for accelerator cavities. Category: Around the World | Tagged: , , , , ,

Advancing superconducting accelerating technology

| 5 January 2012 Last month, the biannual TESLA Technology Collaboration, hosted by the Institute of High Energy Physics, Chinese Academy of Sciences together with Peking University and Tsinghua University, was held at IHEP in Beijing. Category: Feature | Tagged: ,

From CERN Courier: Advances in acceleration: the superconducting way

10 November 2011 The most ambitious future application under study is for the International Linear Collider (ILC), a 500 GeV superconducting linear accelerator. It will require 16 km of superconducting cavities operating at gradients of 31.5 MV/m. Intense research is underway to reach a high yield for high gradients: 30–40 MV/m. New vendors for niobium, for cavities and for associated components are being developed around the world. Category: Feature | Tagged: ,
