‘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: , , , , , , ,

Industrialising the ILC

| 24 October 2013 With the publication of the Technical Design Report, one stage of design and costing for the ILC is complete. Now, US members of the Linear Collider Collaboration must consider what ILC components the US might contribute—and how they will be produced. Category: Feature | 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.

Want a Higgs factory? Damping rings are key

| 12 September 2013 The CesrTA collaboration at Cornell University, US, made important contributions to the design of the ILC damping rings for the recently completed Technical Design Report, including finding ways to reduce a phenomenon known as the electron cloud effect. Post-TDR, the collaboration is pursuing ways to make the damping rings even more effective by better understanding another phenomenon: intrabeam scattering.

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.

On the way to SiD: testing a novel calorimeter

| 11 July 2013 Researchers are taking a step towards the realisation of the International Linear Collider’s (ILC) SiD detector with a test beam of a SiD-specific electromagnetic calorimeter (ECAL) planned for this month at SLAC. Category: Around the World | Tagged: , , , ,

SLAC inaugurates a new era for the future ILC (twice)

| 27 June 2013 The University of Tokyo, CERN and Fermilab weren’t the only locations celebrating the handover of the International Linear Collider’s (ILC) Technical Design Report on 12 June. Category: Around the World | Tagged: , , , ,
