From KEK: Cryomodule for "S1-global" arrived from Italy

Italian made cryomodule being taken out from the container at Superconducting radiofrequency Test Facility (STF) at KEK.
A big Christmas gift arrived at KEK from Italy. On 25 December, KEKís Superconducting radiofrequency Test Facility (STF) welcomed the cryomodule for "S1-global" – a crucial system test towards realizing the International Linear Collider (ILC), a proposed next generation electron–positron collider.

"S1" refers to one of the priority task forces (so-called "S" task forces) for ILC R&D, and the object of S1 is the demonstration of an 8–cavity cryomodule operating at an average accelerating gradient of 31.5 Megavolts per meter, the design gradient for the ILC.

Training the next generation of particle physicists

Students and teachers at the Third Linear Collider Physics School, Ambleside.
A lively debate across age groups and cultures marked the Third Linear Collider Physics School, held in Ambleside, UK, in August. For the first time, designated discussion periods were set aside for up–and–coming scientists to share their work and opinions on the future of accelerator–based particle physics with international experts. The week–long event held at the Ambleside campus of the University of Cumbria in England expanded on the technical and physics issues of past schools with three discussion topics: the "big questions" in the field: electroweak, Higgs physics and accelerator physics; quantum chromodynamics, exotics and cosmology. The school was organised by Andre Sopczak of Lancaster University together with his colleagues Chris Bowdery and Jonathan Gratus.

Reflections on the New Year

As we enter the New Year, it is a good time to review and reflect on our accomplishments during 2009, as well as the present status and prospects for the ILC. I wish I could boldly state that we have made big strides towards making the ILC a reality over the past year, but in reality it was a mixed year. Technically, we have made impressive progress in key areas, while some others areas are languishing due to limited resources. Overall support for the ILC or more generally a next–generation lepton collider remains strong. However, uncertainty regarding the future course of the ILC has created difficulties in planning, as well as some slowdown in our timescale. Our overall plan remains stable: to create a technical design mature enough to propose a global construction project to collaborating governments by the end of 2012. I remain confident we can achieve that goal.
