Register now for ALCW2015: Early registration extended
There are only a few days left to register at more favorable price for The Asian Linear Collider Workshop 2015 (ALCW2015). The Early registration has been extended – but only until Sunday, March 29. Register today!
Being different from the past regional workshops in Asia this workshop is co-organised by KEK, ACFA, and LCC and a new session organisation is attempted; detector sessions consists of several mini-workshops of detector concept and R&D groups.
The workshop, being organised at a critical time for the ILC project development in Japan, will have a special focus on the ILC progress in Japan. Your attendance for his workshop will greatly influence the future of the ILC. Join us from 20 to 24 April 2015, at KEK!
A must-attend is the Tokyo Event on Wednesday – a sSymposium and a special Food Festa to be held on 22 April.
Please see ALCW2015 website for details. Seeing you in Tsukuba and Tokyo !

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.

Barry Barish | 2 October 2008The ILC's beams pass through each accelerating element once before they are directed to collide with the beam travelling in the opposite direction. This poses the two main challenges in the ILC: to achieve a very high gradient in the accelerator in order to make it as short as possible while achieving the desired energy, and to achieve very small beam spots to maximise the probability of collisions by the crossing beams.
