Sachio Komamiya | 12 September 2013The ILC Site Evaluation Committee of Japan has assessed the two candidate sites, the Sefuri mountains in Kyushu (south island of Japan) and the Kitakami mountains in the Tokoku, northeast area, based on technical and socio-environmental criteria. On 23 August, they unanimously concluded that the Kitakami site is the best candidate site for the ILC in Japan.

Steinar Stapnes | 22 August 2013It has been another summer with discussions about future strategies for international particle physics. After work on the European Strategy last summer, the US strategy is on the table this summer. For the linear collider work the strategy processes have been positive, reports Steinar Stapnes, Associate Director for CLIC in the Linear Collider Collaboration. Researchers are closely following decisions being made in Japan.

Lyn Evans | 27 June 2013Physics isn’t usually associated with big emotions, and in the everyday life at the labs this is probably true. However, our field has recently had many momentous events, and the excitement these have caused have made particle physics one of the most popular science topics in the world. Let’s use this momentum to get ahead in our plan to build the ILC – maybe in stages and in Japan?

Barry Barish | 2 May 2013A key feature of the ILC is that it is a single-pass machine. In contrast to a circular accelerator, where the beam goes around many times, the ILC beams pass through each accelerator element only once, including the interaction point. For the accelerator, this means that for each accelerating module, the machine must be very efficient at transferring wall power into the machine beam, with the added requirement that the final beam must emerge with very low emittance so that it can be focused to the very tiny beam spot required to achieve high luminosity. The ATF-2 at KEK is a special test beam line that has been built to demonstrate the ability to achieve ILC-like namometre beam spots and stabilise them. Recent tests have demonstrated beam spots that are within a factor of two of the ILC design and promise to improve in the future.
