From SLAC Today: Simulating a More Efficient Linear Collider

An electromagnetic mode contributing to wakefield effects in a superconducting ILC cavity, as calculated by SLAC's Advanced Computations Department team. Reds, oranges and yellows indicate strong fields, greens and blues weaker ones. (Image courtesy of Greg Schussman.)
Scientists around the world are working hard to hammer out a workable blueprint for the next big particle accelerator, the International Linear Collider, by 2012. A group at SLAC is doing its part, running supercomputer simulations to maximize the accelerator's performance and keep costs down on the proposed multi-billion-dollar collider.

Positron source R&D makes progress

James Rochford checking the performance of the undulator cryomodule.
The team developing the ILC's positron source have every reason to be positive. Recent tests have shown both that the four-meter helical undulator prototype – a device that will produce an intense beam of polarised gamma rays – works in its cryomodule, and that the target that will produce the positrons themselves can reach its design rotation speed of 2000 revolutions per minute.

Viewpoint: Big Science, bigger outreach
...Undoubtedly outreach must convey to society the excitement of scientific discovery and the importance of technological returns. However, in my opinion, the message from science should not stop there.

An official change of name

Ewan Paterson, GDE Integration Scientist at the DESY workshop. He is playing a lead role in integrating the central beam tunnel configuration
A strategy has been emerging over the past months to define a new baseline configuration for the ILC Technical Design Report (TDR). Beginning with the well-established Reference Design Report (RDR) configuration, we are selectively proposing changes that can significantly improve the cost to performance to risk. The anticipated final configuration has been referred to as the “Minimum Machine,” however this misnomer has caused endless misunderstandings and misinterpretations. A new, more descriptive name for the process we are undertaking, Accelerator Design and Integration (AD&I), became official at the first working meeting towards defining a new ILC baseline held at DESY from 28 to 29 May. Much was accomplished and points of contention were defined at this lively interactive working meeting.

Image of the Week
Not bad!
Last week we showed you a picture of a couple of shoes asked you to send us your theories as to what those shoes are up to and why. While one person managed to identify all of the shoe owners (congratulations, Maxine — but you had a head start because you see those shoes all the time!) another guessed that it's "School kids all heading out for summer." Two readers obviously heard fiddles and tin whistles playing: "really smart physics people practicing "RIVERDANCE" while on layover at the Dublin Airport" guessed one, while the other thinks that the "GDE is starting to incorporate Irish jigs into their regular routines to encourage creative thinking and new ideas." And what is it really? Participants at the re-baseline meeting held at DESY (see this week's Director's Corner) continuing discussions in a German beer garden. Well done, everyone!
