A conformal approach to cavity coating

| 28 April 2011 Argonne researchers are working to coat accelerator cavities with perfectly uniform atomic layers of niobium. The thin film technology could help slash production and operation costs in particle accelerator programmes while boosting accelerator performance. Category: Around the World | Tagged: , , , , ,

A laboratory without walls

and | 14 April 2011 The France-China Particle Physics Laboratory is a lab without walls, enabling Chinese and French particle and accelerator scientists to work together towards the new energy frontier with experiments such as the LHC and the ILC. Its fourth annual workshop took place in Shandong University, Jinan, China from 7 to 9 April 2011. Category: Around the World | Tagged: , , , , , , , , , ,

A robot to watch out for defects

| 14 April 2011 A small group of young researchers at DESY, Germany, is working on a robot that could drastically reduce the time it takes to optically inspect a cavity. Their work covers everything from the pure mechanics of the workbench and fine-tuned motors for moving the heavy parts to developing sophisticated methods of automatically analysing the pictures. Cavities might eventually pass the check in two hours instead of the one-and-a-half days it takes today. Category: Around the World | Tagged: , , , , ,

The millisecond challenge of the flux-concentrating magnet

| 10 March 2011 The ILC’s flux-concentrating magnet operates much like someone in a high-intensity interval workout: it fires for only a small fraction of the time, but when it does, it takes a beating. Scientists at Lawrence Livermore National Laboratory have finished the intense work of designing the flux concentrator, modelling its operation and potential hurdles.

A niobium company visit in Ningxia, China

| 24 February 2011 On 18 February 2011, a delegation of Global Design Effort representatives visited the Orient Tantalum Industry Co. Ltd (OTIC), Ningxia, a leading niobium company in China. The group consisted of ILC project managers Akira Yamamoto and Marc Ross, together with Robert Rimmer of Thomas Jefferson Laboratory in the US, accompanied by Asian Linear Collider Steering Committee Chairman Jie Gao and ILC group member Jiyuan Zhai of the Institute of High Energy Physics (IHEP) in Beijing.

Many small klystrons for operability and flexibility

| 10 February 2011 Scientists at KEK in Japan are currently developing a 'distributed radiofrequency system' for delivering radiofrequency power to the ILC accelerating cavities. An alternative solution to the 'klystron cluster scheme', this powering method accommodates the ILC’s new one-tunnel design. Category: Around the World | Tagged: , , , , , ,

Spreading the positron energy around

| 10 February 2011 Scientists from the Cockcroft Institute, Daresbury Laboratory and Lawrence Livermore National Laboratory work on a rotating positron target for the ILC that can hold its own while producing about 1014 positrons per second for collisions with electrons.

From CERN: CERN announces LHC to run in 2012

3 February 2011 Geneva, 31 January 2011. CERN1 today announced that the LHC will run through to the end of 2012 with a short technical stop at the end of 2011. The beam energy for 2011 will be 3.5 TeV. This decision, taken by CERN management following the annual planning workshop held in Chamonix last week and a report delivered today by the laboratory’s machine advisory committee, gives the LHC’s experiments a good chance of finding new physics in the next two years, before the LHC goes into a long shutdown to prepare for higher energy running starting 2014.

Clustering klystrons to pool power

| 3 February 2011 Though it doesn’t sound like a way to tidy up, the alliteratively named klystron cluster could be the mechanism that helps streamline the large-scale design of the ILC. Scientists at the Stanford Linear Accelerator Center (SLAC) in the US are currently developing the klystron cluster scheme, a new kind power-delivery system for radio frequency cavities that distributes power from a common conduit.

Cornell makes progress on Energy Recovery Linac

| 27 January 2011 The idea behind recycling is straightforward: reuse what you have to make more of the same. Applying this concept, however, is seldom simple.  In the case of Cornell University's Energy Recovery Linac (ERL), recycling energy to generate particle beams requires technological advancements that are born from decades of research.  If scientists there fulfil their mission, they'll be able to use particle beams to accelerate particle beams, producing some of the brightest bunches to be made by an accelerator.
