Commissioning has begun at the Japan-based Accelerator Test Facility 2, a major technology test bed for future accelerators, including the proposed International Linear Collider, or ILC. During the two-year commissioning process, SLAC National Accelerator Laboratory physicists are shuttling back and forth to KEK, the high-energy accelerator lab in Tsukuba, to join an international team of scientists working around the clock to get the accelerator's final focus system up and running. When fully commissioned, this system will squeeze the facility's electron beam down to a slender ribbon just 35 nanometers thick—the narrowest beam of particles ever achieved.

ILC bloggers join Quantum Diaries
“This is going to be a new, hopefully interesting and enjoyable experience,” says Frank Simon, in his opening post.

What do they know that we don't?

Scientists at the Dutch national lab Nikhef seem to know more about the future of particle physics than they let on... this countdown was spotted at a coffee break during a recent meeting there. It's no April fool's joke, but it isn't quite accurate either... “We used to count down to the LHC start-up,” explains Nikhef communication officer Gabby Zegers. “Now that that has happened we needed a new date to count down to, and we randomly set the ILC starting date to 2 February 2023.” Who knows, maybe they do know more than the ILC management...

Neutrinos in Venice

The optical telescope gave us a new way to look at the sky
Last month I had the pleasure of participating in the "XIII International Workshop on Neutrino Telescopes" at the "Istituto Veneto di Scienze, Lettere ed Arti" in Venice Italy. This workshop, inspired and run by Professor Milla Baldo Ceolin (Padova University), has become an institution in neutrino physics. The meeting is based on review talks followed by extensive discussions and the programme broadly covers topics related to neutrino physics, astrophysics and cosmology, singling out the most interesting current results and problems. This year’s meeting was especially interesting to me in how it demonstrated the relationships between accelerator and non-accelerator physics and how much closer astrophysics is becoming to particle physics.

Fourth International Accelerator School for Linear Colliders
The Fourth International Accelerator School for Linear Colliders (2009 LC School) will be held from 7-18 September 2009 at Hotel Jixian, Huairou, near Beijing, China under the auspices of the GDE, ILCSC and ICFA Beam Dynamics Panel. The Institute of High Energy Physics (IHEP) will be the host institution. The school will take a maximum of 70 students from around the world. Students will receive financial aid including travel (airfare, lodging, meals and local transportation, full or partial). Only online application will be accepted. The deadline is June 1, 2009.
