World Cup Snapshots

SLAC's Italian BaBarians celebrating their team's victory
If you were anywhere in Germany during the last month you couldn't have missed it: it was football world cup. Black-red-and-golden flags flying from windows, fluttering behind cars, decorating t-shirts, socks, beer mats, faces, shop windows, newspapers. If by chance you went to Hamburg you were greeted with a beautiful array of bright blue goals shining from every high-rise roof, harbour crane and all other landmarks in the city, and the public transport system didn't only tell you when the next train was due to arrive – it also had updates on the goals of every match that was on.

And if, while you were in Hamburg, you paid a visit to DESY during a match you could hear the noise from the nearby football stadium through the trees. Sometimes the voice of HCal expert Erika Garutti would drift through the trees as well: on the morning of the day of the Italy – Czech Republic match in the Hamburg stadium, the organisers suddenly appeared at the DESY gates, desperate: they urgently needed an Italian to read and record announcements for the Italian football fans. Erika stopped preparing the HCal's shipment to CERN for a while and will go down in history as the voice who says in Italian 'Please have your bags ready for security checks.'

Feature Story
The Joy of Large Grain Niobium

Like salt crystals, niobium crystals, or grains, can be grown in either larger or smaller sizes. The individual crystals or grains can easily be seen in large-grain niobium.

With detailed recipes for rolling, baking and rinsing, one might think that gourmet chefs are building, designing and testing the superconducting cavities for the International Linear Collider. On a quest to design the most efficient and cost-saving cavity for the ILC, the physicists who are actually developing the recipes are not a far cry from chefs. And just as chefs experiment by mixing spices to create new flavours, scientists involved in superconducting cavity technology are trying out alternative ingredients by testing such things as large grain and single crystal niobium.

Named after Niobe, the granddaughter of Zeus, niobium is a superconductor – a substance with no electrical resistance in the superconducting state. Because niobium is the elemental superconductor with the highest transition temperature, it has been the choice material for many accelerator projects using superconducting technology; it is therefore also the material of choice for ILC cavities (see symmetry magazine, September 05). A material made up of crystals or grains, niobium can be grown in larger or smaller sizes – just like salt crystals. Large-grain niobium therefore simply consists of larger niobium crystals. While the cavities in the ILC will all be made out of solid niobium (potentially a cost upwards of 300 million dollars), manufacturing cavities from large grain or single crystal niobium may cut down on expenses by eliminating some of the treatments that are necessary for fine grain cavities.

Rushed decision on collider would limit useful options
SIR Your Editorial about the International Linear Collider (ILC), "Making collider endorsement count" (Nature 440, 1089; 2006), states that CERN has insisted "that decisions about the siting of the ILC be delayed until an accelerator technology it is trying to develop is ready". This is untrue.

At what point does a country decide that its economy is strong enough to allow research into particle physics? "We condemn ourselves to permanent second-class status if we decide that we cannot do research into the beginning of the universe," he argues.

Director's Corner
Vancouver Linear Collider Workshop/GDE Meeting

Vancouver Linear Collider Workshop, 19-22 July 2006
Today's issue features a Director's Corner from Gerry Dugan, GDE Americas Regional Director.

The first GDE meeting in the Americas region since the Snowmass 2005 workshop will take place next week on 19-22 July, as a joint meeting with the American Linear Collider Physics Group (ALCPG) at the University of British Columbia in beautiful Vancouver, Canada. Information about the workshop and a complete agenda are available online.


Gerry Dugan

The meeting will bring together several hundred physicists from around the world, who are working on both the accelerator and detector aspects of the ILC. More than 150 participants have expressed an interest in attending the GDE presentations, which will be held mostly in parallel with the ALCPG sessions. There will be an introductory joint plenary session on the morning of 19 July and a closing joint plenary session on 22 July.

The GDE sessions will focus on the status of the Reference Design Report (RDR) and the accompanying cost estimate. The afternoon of 19 July and the morning of 20 July will be devoted to GDE plenary sessions in which the RDR Area, Technical and Global Systems Leaders will give reports on their work. This will be followed by a series of parallel working sessions on the afternoon of 20 July 20 and all day on 21 July. During these sessions, the working groups will be able to interact with each other, review their current issues, and make plans for the next steps in developing the RDR and cost estimate. Finally there will be three plenary sessions devoted to reports on the global R&D program on 22 July.

Announcements
ALCPG and GDE Host Town Hall Meeting at VLCW06 - Questions Needed!
The Vancouver Linear Collider Workshop is less than a week away, and the organisers need your input now. Please submit your question to communicators@linearcollider.org. Organised by the American Linear Collider Physics Group and the Global Design Effort, the purpose of this town hall meeting is to establish stronger communication between the accelerator and detector communities for the ILC. A panel comprised of GDE and ALCPG members will answer questions and moderate the discussion.
