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.

If you talk about next year, devils will laugh at you. This is a Japanese saying that corresponds to the English saying, "Don't count your chickens before they're hatched." I do not want to be laughed at by the devil, but I would like to write about Building 2 at KEK.

Every month, a lot of Asian researchers come to KEK to conduct their research or experiments. “We have had 45 visitors for fiscal year 2007 so far, including ten Korean researchers,” says Tomiko Shirakata, secretary at KEK’s Linear Collider Project Office. Shirkata is in charge of KEK’s visitors programme activities and provides all visitor supports such as arranging logistics, dealing with the consulate service for visa applications, and giving tips on how to spend days off in Japan. KEK launched the visitor programme in April 2006 aiming to facilitate the foreign researchers’ activities in Japan, especially for Asian researchers and students, who may have difficulties to conduct research overseas for some country-specific reasons.

Men and women wearing gaudy dresses, looking for customers under garish neon signs – this is a common sight in Kabuki-cho, Shinjuku, a famous entertainment and red-light district in Tokyo, Japan. Walking down an alleyway that has countless bars and nightclubs, you will see a hand-written sign posted on the billboard of a shabby building that says, “The Accelerator’s Night 3.”
