The secret life of cavities – not so secret any more

| 24 May 2012 There’s no doubt that the life of a cavity is exciting – lots of power, whizzing particles, superconductivity, the lot. How does it get there, what are the stations of its life? A new photo series is in production that follows a cavity from niobium ingot to cryomodule, and an exhibition of these images opens next week at DESY in Germany.

If the particles won’t come to the detector…

| 10 May 2012 Five shafts, pacmen shields and moving platforms: the design for the hall in which the ILC detectors will sit, be pushed and pulled, record data, get upgrades and maintenance is now final, at least for an ILC that is not built underneath mountains.

Crescendo for European infrastructures

| 12 April 2012 The AIDA community takes stock of its first year of R&D activities. Twenty-three European countries are working on a variety of infrastructures that help today's researchers plan the detectors of the future - from linear colliders to neutrino facilities.

More knobs, more knowledge

| 29 March 2012 In their unflagging quest to achieve higher gradients for the ILC, scientists in the 9-mA study programme at DESY’s FLASH facility develop a better knack for automating accelerator voltages, helping keep cavity gradients high and the whole system stable.

The science of showers

| 12 January 2012 Good timing is a virtue. Just as comedians have to wait for just the right moment to deliver their punch line, linear collider physicists need to know when to make cuts. These cuts separate phenomena called particle showers from each other, making it possible for the physicists to tell which reaction originated from which collision. Two German PhD students have built a test device that is supposed to get behind the precise timing of showers. Category: Profile | Tagged: , , , ,

Successful slamming with music and the ILC

| 1 December 2011 In a nationwide “Weltmaschine day” to celebrate the second anniversary of collisions in the Large Hadron Collider, universities and institutes all over Germany not only presented the latest results from the LHC to crowded lecture halls, but also showed the fun side of physics in slams and exhibits. A slam about the ILC came first at DESY in Hamburg. Category: Feature | Tagged: , , ,

Setting the stages for shorter bunches

| 23 November 2011 One of the busiest places in the ILC design is the central region. It’s where it all happens: the beams get squeezed and focused and kicked into collision and out comes physics. To make sure that everything works to perfection and to reach consensus on the design, the central region has just undergone a technical baseline review, along with areas like the connection between damping ring and main linac. One of the core decisions for the latter: a two-stage bunch compressor for shorter beams. Category: Feature | Tagged: , , , , , ,

Hungry for science

| 3 November 2011 Last Saturday’s Open Day and Science Night at DESY in Hamburg, Germany, attracted more than 13 000 visitors. The lab presented its many fields of research, including the ILC, in a tent outside the entrance to the HERA accelerator tunnel. ILC detector developers and accelerator experts explained what the project is all about. 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: , , , , ,

European detector experts join in the AIDA chorus

| 3 March 2011 European accelerator and detector sciences kick off the AIDA project, a four-year plan that will allow easier coordination and collaboration among the continent's particle physics institutes. Category: Uncategorized | Tagged: , ,
