Rika Takahashi | 24 July 2014Last month, LC NewsLine reported the achievement of the world’s smallest beam size of 55 nanometres at the ATF2 facility at KEK. At two international conferences held in June and July, the next record of 44 nanometres was reported by Kiyoshi Kubo and Shigeru Kuroda.

Akira Yamamoto | 5 June 2014Regional Director Akira Yamamoto reports from the Americas Workshop on Linear Colliders (AWLC) 2014 held last month at Fermilab, US. A new official structure gives weight to contributions from scientists who used to juggle linear collider work and their projects “at home”, and in general he observes that big progress is common when a technology hasn’t reached a certain stage of maturity, but once it has, the steps become smaller, but almost more important.

Stephanie Hills, STFC's UK Communications and Innovation Officer | 1 May 2014The CLIC accelerator collaboration has elected a new spokesperson. Phil Burrows of the University of Oxford succeeds Roberto Corsini of CERN. Over the next three years, Burrows will be engaging with the institutes that are members of CLIC and helping to ensure that CLIC’s R&D programme pushes ahead during the critical phase ahead of the next update of the European strategy for particle physics. Corsini will continue his technical leadership of CLIC/CTF3.

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.

Daisy Yuhas | 21 March 2013What makes the ILC beams far smaller than a human hair? A series of magnets referred to as the ‘final focus,’ designed to maximise chances of collision at the heart of the ILC detectors.

Barry Barish | 7 February 2013The draft of the ILC Technical Design Report (TDR) was completed last November and submitted for review. On 13 and 14 December, the TDR underwent a technical review at KEK by an augmented ILCSC Program Advisory Committee. The review report endorses the technical design we have presented and recommends “no changes in the TDR.” The report does identify areas and items to address in the future.

Toshiaki Tauchi | 25 October 2012KEK's Accelerator Test facility (ATF) is up again after its summer shutdown. After several improvements to beams size monitors, multi-ole magnets and the organisation structure, the international team is looking forward to squeezing the beam size further and further towards the 37 nanometres required for the ILC.
