ECFA Linear Collider Workshop: registration is open
The next ECFA Linear Collider Workshop which will be held in Santander (Spain) from 30 May to 5 June 2016. It continues the international workshops devoted to accelerator, physics and detector aspects of future high-energy electron-positron linear colliders (ILC, CLIC). The workshop is co-hosted by ECFA and LCC and will consist of accelerator sessions, several mini-workshops of detector concept and R&D groups as well as physics and plenary sessions. Find out more about the meeting and the programme or register here.
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.

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.
