US scientists, with assistance from private industry have designed the newest iteration of a special chip with a 3D integrated circuit, for the ILC's vertex detector that will help measure properties of incoming particles at a higher resolution than previously achievable. The ILC is now another step closer to being an engineering reality.

A team at Fermilab has developed a new technique to use a magnetron to power a superconducting radio-frequency accelerating cavity, potentially saving hundreds of millions of dollars in the construction and operating costs of future linear accelerators.

All eight cavities in an ILC-type cryomodule achieved the accelerating gradient specified for the International Linear Collider earlier this month. The cryomodule, CM2, was developed and assembled to advance superconducting radio-frequency technology and infrastructure at Americas-region laboratories.

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.

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.

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.

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.

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.

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.

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?
