Elizabeth Clements | 18 October 2007International Linear Collider workshops tend to be hectic. Meetings are scheduled back to back and often overlap. The days start early and end late. The coffee breaks are a brief, necessary respite. In a virtual collaboration, the three Conventional Facilities & Siting Group leaders understand that face to face time is precious, making it easy to spot the trio together. A meal together here and a coffee there can add up to a lot, and the CFS group leaders take advantage of every minute. For this next workshop at Fermilab from 22-26 October, however, there will be a new CFS co-leader on the block – John Osborne from CERN.

Barbara Warmbein | 11 October 2007Many scientists working on ILC detector simulation know: Mokka can give you sleepless nights. This has nothing to do with caffeine, however - Mokka is a software that lets you run full simulations of events in future ILC detectors. It uses the Geant4 simulation tool, and ILC detector people around the world use it – and struggle with it sometimes. If you’re one of those people and are looking for answers (or maybe you want to share a particularly interesting line of code?), the website forum may be the right place for you.

Barbara Warmbein | 13 September 2007Alain Hervé already has the experience of building two enormous detectors under his belt, and it looks like he is going to help in a third one. Technical coordinator at CERN of both L3 at LEP and CMS at the LHC, the Breton has now been called as an expert to help in the interaction region design, cavern and detector assembly planning for the ILC and its detectors. He is taking part in preparatory phone conferences for the IRENG workshop and co-convenes Work Group A that looks at how to design, install and open experiments.

30 August 2007At Texas A&M University, a team led by Peter McIntyre has developed a new design for superconducting cavities for linear colliders, perhaps even the International Linear Collider. Their polyhedral cavity design, which is only in its beginning stages and requires a significant amount of R&D, could offer such benefits as increasing the accelerating gradient and making the cavities more cost-efficient.

23 August 2007As a virtual collaboration, members of the ILC community took advantage of last week’s Lepton Photon conference and held parallel meetings for the GDE Executive Committee, ILC Steering Committee (ILCSC) and the International Committee for Future Accelerators (ICFA).

Rika Takahashi | 2 August 2007Every 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.

Rika Takahashi | 26 July 2007Men 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.”

19 July 2007While other labs concentrate on developing superconducting cavities for the International Linear Collider (ILC), SLAC is focusing on the technology needed to power them. In addition to klystron, modulator and radio frequency (RF) distribution development, this effort includes a coupler program. A coupler is basically a coaxial transmission line that connects normal-conducting, air-filled, room-temperature waveguides to each superconducting, evacuated, super-cold accelerator cavity. The couplers are complex devices due to the various requirements imposed on them; they must convert the RF to a coaxial mode, transmit high power (~300 kW), be mechanically flexible for cool-down of one end to 2K (-271

Elizabeth Clements | 12 July 2007Amidst the corn fields in DeKalb Illinois, 65 miles to the west of Chicago, a group of 22 physicists and students, who are members of the Northern Illinois Center for Accelerator and Detector Development (NICADD) at Northern Illinois University, contribute to the International Linear Collider in more ways than one. From beam dynamics to calorimetry hardware to simulation software, the ILC group at NIU covers it all. Because the group consists of such a large number of undergraduate and graduate students, training the future generation of scientists – who may be running the actual ILC one day – is perhaps one of their largest contributions of all.

Perrine Royole-Degieux | 5 July 2007To fulfil the detailed requirements of the ILC, each device from the particle source has to be controlled with high precision, stability and reproducibility. At Warsaw, Poland, a team of engineers works closely with particle physicists on electronics and photonics to develop electronic systems, instrumentation and microprocessors for cavity RF controls at the highest performance and for the lowest cost. This group motivates and encourages young researchers to join them by organising regular symposiums.
