New cavity production facility for future industrialisation

| 30 April 2009 (...) One of the most important plans for the ILC project is to build a new superconducting radiofrequency (rf) cavity production facility on KEK premises, aiming to gain experiences for industrialisation and future mass-production. Category: Director's Corner | Tagged: , , ,

From SLAC Today: A Flight Simulator for the World’s Smallest Beam

2 April 2009 Commissioning has begun at the Japan-based Accelerator Test Facility 2, a major technology test bed for future accelerators, including the proposed International Linear Collider, or ILC. During the two-year commissioning process, SLAC National Accelerator Laboratory physicists are shuttling back and forth to KEK, the high-energy accelerator lab in Tsukuba, to join an international team of scientists working around the clock to get the accelerator's final focus system up and running. When fully commissioned, this system will squeeze the facility's electron beam down to a slender ribbon just 35 nanometers thick—the narrowest beam of particles ever achieved.

From KEK: New beam line for R&D of nano-meter electron beam has been started at Accelerator Test Facility

22 January 2009 A new beamline for R&D toward nano-meter electron beam has started operation at KEK's Accelerator Test Facility - ATF. This new beamline, called ATF2, is an extension of ATF, and the focus of the research there will be on establishing the technologies for creation and control of a nano-meter-sized electron beam.

Pixel collaboration

13 November 2008 Plans are taking shape to form a new group to coordinate and stimulate R&D on monolithic and vertically integrated pixel detectors for scientific applications in high-energy physics and beyond. In a joint message, the directorates of CERN, KEK and Fermilab have offered their support. They suggested the formation of a regionally balanced coordination board to take this forward. From discussions in recent reviews and workshops, we think there is an opportunity for the many efforts underway worldwide to benefit a larger community. We already have strong collaborations for the development of vertical integration and monolithic active pixel sensors (MAPS). The new world-wide effort would build upon the existing collaborations and open the technology developments to other scientific areas. We will discuss how best to achieve this at upcoming meetings. Our suggestions will then be comunicated to the directorates of CERN, KEK and Fermilab. Category: Feature | Tagged: , , , , ,

Preparations for S1-global at the STF at KEK

| 9 October 2008 Research and development on superconducting radiofrequency (rf) cavities, cryomodules and operational units is at the core of our programme to develop the technologies, the best possible machine design and an implementation plan for the ILC.

Achieving tiny beam spot sizes with ATF2

| 2 October 2008 The 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.

Accelerator community communicates

| 25 September 2008 On Wednesday, 24 September, KEK held a symposium entitled “Starting up the world's most powerful accelerators: LHC and J-PARC” in Tokyo. This symposium was the second one in a series of symposiums aiming for gaining more understanding of accelerator science. The main audience of this symposium was the industry. “We would like to place an emphasis on the collaboration between industry, the universities and the laboratories which enable those big accelerator projects,” said Mitsuaki Nozaki, the chief organiser of the symposium. “I believe that efforts like these are essential to realise another big accelerator project in the future, such as the ILC,” he added.

Science Fiction meets Science Non-Fiction

28 August 2008 On 18 and 19 August, a total of 38 leading Japanese creators, including science-fiction and fantasy writers, animation movie directors, comic artists, illustrators, and photographers, visited J-PARC (Japan Proton Accelerator Complex) in Tokai-village and KEK Tsukuba campus. This visit was coordinated by Junpei Fujimoto, a KEK scientist who is active in ILC outreach activities. Category: Feature | Tagged: ,

Enjoying cool science

| 24 July 2008 On the first day of a three-day weekend with a Japanese national holiday, Day of the Sea, about 300 people changed their destination from seaside to science. They enjoyed talks on cool science on a hot Saturday afternoon in Tokyo at a symposium called “Denshi-koraidah ga toku ucyu sousei no puzzle (Solving the puzzle of the universe with electron-positron colliders),” organised by KEK. The symposium introduced the science to be delivered by future electron-positron colliders to a non-scientific audience. The symposium was a two-part event. The first part consisted of talks by three top-notch scientists – Hitoshi Murayama, Director General of Institute for the Physics and Mathematics of the Universe (IPMU), Shoken Miyama, Director General of the National Astronomical Observatory of Japan, and Atsuto Suzuki, Director General of KEK. The second part was a panel discussion with those three scientists and Shinji Kimoto, a science-fiction novelist who wrote the award-winning novel 'Kamisama no Puzzle', and was moderated by Shigehiko Nakajima, Editor-in-Chief of Nikkei Science Magazine, the Japanese edition of Scientific American.

A personal tribute to Yoji Totsuka

| 17 July 2008 High-energy physics lost a giant in our field - and I lost a very good personal friend - when Yoji Totsuka, the former Director General of KEK, died of cancer at the age of 66 last week. I would like to pay special tribute to a great scientist and wonderful human being. Category: Director's Corner | Tagged: ,
