Wise counsel for Europe

It is easy to get snowed under with information in Europe. An advisory board helps Director Brian Foster stay on top of things. (Image: ESA)
Even – or especially ? – directors cannot have their eyes everywhere. They need to gather information and be able to judge things – but how do you do this on a continent where labs can be 3,000 kilometres apart, every country has different forms of governance, and science policy and funding agencies couldn’t be harder to grasp? Global Design Effort European Regional Director Brian Foster has found his own solution. If a reasonable number of high-level European physicists and lab directors come together in one place, he often calls for a meeting of his Advisory Group. One of these European Advisory Group meetings has just happened at DESY, slotted in right after the ICFA and ILCSC meetings, to minimise travel.

Feature Story
Looking inside

High-resolution surface inspection camera for superconducting cavities with Yoshihisa Iwashita (left) and Yujiro Tajima (right) from Kyoto university.
At the ILC, roughly 16,000 superconducting RF cavities made of pure niobium will accelerate electrons and positrons to the high energy of 500 GeV. Each one-metre-long cavity consists of nine cells, polished to provide micrometre-level surface smoothness and absolutely no impurities. The inside of the cavities need to literally sparkle since any surface blemishes or dust could cause them to lose their superconductivity, making them unable to sustain the electric field needed to accelerate particles. ILC scientists around the world are devoted to trying to get a higher yield rate for producing good-quality cavities by improving surface treatment methods and inspection procedures. A group of scientists from Kyoto University and KEK jointly developed the novel inspection system to take a close look at the interior surface of the cavities, and produced remarkable results.

Physicist Neil Turok: Big Bang Wasn't the Beginning
For decades, physicists have accepted the notion that the universe started with the Big Bang, an explosive event at the literal beginning of time. Now, computational physicist Neil Turok is challenging that model -- and some scientists are taking him seriously.

AAAS: Large-scale collaborations in physics

Director's Corner
Contemplating large international collaborations

Lawrence Krauss (back), Norbert Holtkamp, Robert Aymar and Barry Barish during the AAAS session.
The American Association for the Advancement of Science (AAAS) annual meeting took place from 14 to 18 February in Boston, US, under the theme "Science and Technology from a Global Perspective." The AAAS is the meeting ground for the broad range of sciences in the US, from biology to physics. This association also publishes the very famous weekly journal Science. In the spirit of the conference theme, Lawrence Krauss, Case Western Reserve University, and Maria Spiropulu, CERN, organised a very provocative and interesting special session entitled, "Large-Scale International Collaborations and the Future of Physics."
