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 !

Barbara Warmbein | 31 July 2008In a linear accelerator, energy conservation is not really on the achievement list. To get up to the required luminosity, accelerator experts have one chance to push the particle beams to their limits, putting much energy into the bunches, correcting, scraping and tweaking them along the way only to smash them into each other and direct the straggly remains into a dump. Not so an Energy Recovery Linac, currently at the design and first prototype stage at Cornell University. The electron beams also get dumped after one run, but before that happens, they are tricked into handing over their energy back to the superconducting machine that accelerated them.

Barbara Warmbein | 10 July 2008There may not have been a ribbon-cutting ceremony or speeches by heads of state. But the official kick-off of Cornell University's CESR storage ring as ILC damping ring test facility pleased the nearly 40 participants at this week's "Joint CesrTA Kickoff Meeting and ILC Damping Rings R&D Workshop (ILCDR08)" enormously. “CesrTA will give us a detailed picture of the how electron cloud builds up under a range of conditions, of how an ultra-low emittance positron beam interacts with the electron cloud, and of how beam instabilities driven by the electron cloud develop,” says Andy Wolski, damping ring group leader based at the Cockcroft Institute in the UK. “In this respect CesrTA plays a critical role in validating the decision to reduce costs by eliminating the second positron damping ring.”

Barbara Warmbein | 29 May 2008Sometimes even pretty straightforward and remarkably logical ideas take several moves before they become a reality. Take the planned damping rings for the ILC, for example. In the ILC, compact bunches of electrons and positrons are made to collide at very high energy. In order to ensure a high rate of particle collisions, the bunches are cooled in damping rings prior to acceleration. In a cold bunch, the particles are all very close together and travelling in very nearly the same direction with very nearly the same velocity. (In a hot bunch, as in a hot pot of water, the particles are more dispersed and are all moving in different directions.)

22 February 2007In the end of January, the Laboratory for Elementary Particle Physics (LEPP) at Cornell University hosted collaborators from KEK, Lawrence Livermore National Laboratory, Argonne National Laboratory and Alfred University (an undergraduate University in New York State) to conduct electron cloud studies using the CESR storage ring. CESR is unique in that it is a “wiggler dominated” storage ring capable of storing intense beams of both electrons and positrons, singly or simultaneously.
