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.

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.

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.

On the last day of May, ILC scientists and engineers enjoyed a barbecue, sushi and Ton-jiru miso soup with pork and vegetables in front of the ATF (Accelerator Test Facility at KEK) container. This gathering, called the ATF end-of-run party, has been a routine event for over ten years.

The coordination of superconducting radiofrequency R&D is central to the Global Design Effort's mission of bringing the design for the ILC to the point we can make a robust proposal to our governments.

One of the more difficult problems in conducting large-scale science projects is the process of decision making. The ability to make good decisions in a timely way can be an enormous challenge and can differentiate good management from not-so-good management.

Superconducting cavities are the core, the heartbeat of the International Linear Collider. Their inside will be polished to literally make them sparkle without any speck of dust or crack because these could cause a decline of performance of the accelerator. There are several methods to polish the inside of the cavities, and electropolishing (EP) is one of them. The new EP system at KEK has started its test-run in January, and scientists are gathering basic data to evaluate the machine's capability.

Kazuko Toyomura has been assisting KEK's ILC activity for four years, and since Sakue Yamada was appointed as a Research Director last October, her involvement has become even deeper. “She is not 'officially' assigned as secretary for the International Detector Advisory Group (IDAG), but she has been taking care of my activities,” says Yamada. Toyomura is a secretary for the Institute of Particle and Nuclear Studies at KEK. Other than her new role in ILC detector community, Toyomura is managing the day-to-day activities for KEK's ILC detector and ZEUS experimental groups, including travel arrangements, guests and visitors support, and helping post-doc students.

At the ILC, roughly 16,000 superconducting RF cavities made of pure niobium will accelerate electrons and positrons to the high energy of 500 GeV. Each one-metre-long cavity consists of nine cells, polished to provide micrometre-level surface smoothness and absolutely no impurities. The inside of the cavities need to literally sparkle since any surface blemishes or dust could cause them to lose their superconductivity, making them unable to sustain the electric field needed to accelerate particles. ILC scientists around the world are devoted to trying to get a higher yield rate for producing good-quality cavities by improving surface treatment methods and inspection procedures. A group of scientists from Kyoto University and KEK jointly developed the novel inspection system to take a close look at the interior surface of the cavities, and produced remarkable results.

The world’s first horizontal multi-beam klystron has started its site acceptance test at DESY. Built by the Japanese company Toshiba, it is the first of three prototypes from different companies to arrive for the test that will determine whether the new klystron design works. The 10-megawatt horizontal klystron was developed for the European X-ray Free Electron Laser (XFEL) and is also part of the reference design for the ILC.
