25 June 2009Scientists just finished successfully testing the first particle flow algorithm hadronic calorimeter for the International Linear Collider, with unprecedented granularity and novel readout technology. This sub-detector, the analog hadronic calorimeter, was built by the CALICE (Calorimeter for the Linear Collider Experiment) collaboration and is one of several options for the hadronic calorimeter of a future ILC detector.

Barbara Warmbein | 11 June 2009The team developing the ILC's positron source have every reason to be positive. Recent tests have shown both that the four-meter helical undulator prototype – a device that will produce an intense beam of polarised gamma rays – works in its cryomodule, and that the target that will produce the positrons themselves can reach its design rotation speed of 2000 revolutions per minute.

Barbara Warmbein | 4 June 2009A few weeks after the first big Accelerator Advisory Panel (AAP) review at the TILC09 meeting in Tsukuba, Japan, the panel has published its review results (see also the two most recent Director’s Corners on this topic). After two months of preparation, an intense week of presentations and another few weeks of writing up the results, the 13 members – ten ILC researchers and three from outside the linear collider world – presented a set of recommendations that intend to lead the ILC's most important areas of research and development to successful completion by the end of the Technical Design Phase (TDP) in late 2012.

28 May 2009In early September 2009, Beijing will serve as host city to roughly 70 outstanding physics students from the Americas, Asia and Europe for a ten-day intensive course entitled the Fourth International Accelerator School for Linear Colliders. The Institute of High-Energy Physics (IHEP) will be the host institution. Led by scientific researchers and academic faculty, the rigorous curriculum will address such topics as linear colliders, the muon collider, radiofrequency technology and damping rings. It will be yet another step forward in the tenure of the school which took place at such locations as Hayama, Japan, Erice, Sicily, Italy, and Oakbrook, Illinois, U.S.A., in previous years.

Perrine Royole-Degieux | 14 May 2009Since the end of March, when the detector concept groups delivered their Letters of Intent, the International Detector Advisory Group (IDAG) has been experiencing an intense period. At TILC09 in Japan, the panel worked and interviewed the detector concept groups for three days. All sessions were closed to other participants, but ILC NewsLine wanted to know more about what happened there and understand details about the whole process of detector evaluation.

Barbara Warmbein | 14 May 2009Some 400 pages of calculations, simulations, detector descriptions, estimates, some 1000 signatories from all round the world, hours spent on the phone or clustered around conference tables – a lot of hard work and careful thinking went into the Letters of Intent (LOI). Each of the three submitted letters – for ILD, for SiD and for the 4th concept or 4th for short – managed to meet the deadline, and even though they didn’t manage to stick to the recommended page limit of 100, they were all accepted and are being scrutinised by the international detector advisory group IDAG (see this week’s other feature). This is a story about how an LOI is written, as told by the authors and editors.

Barbara Warmbein | 7 May 2009Antimatter is likely to matter quite a lot in the next weeks. Hollywood has made its movie version of Dan Brown’s thriller Angels and Demons, directed by Ron Howard and starring Tom Hanks as Robert Langdon, and the film will hit cinemas around the world starting on 13 May. If you know the book you’ll know what ILC NewsLine has to do with it: it’s all about antimatter!

Perrine Royole-Degieux | 30 April 2009While most of the ILC community was meeting at Tsukuba, Japan for TILC09, a new member had his first day at Fermilab. Andre Sulluchuco has just joined the team of the now five ILC communicators, taking over for Elizabeth Clements. He will closely collaborate with his partners from abroad: Rika Takahashi and Misato Hayashida in Asia, Barbara Warmbein and Perrine Royole-Degieux in Europe.

Barbara Warmbein | 23 April 2009In order to have a detailed and visual model of the ILC tunnels, shafts, accelerator components, beam pipes and support lines, a team from around the world has just shown that they can produce three-dimensional ILC models. These will be crucial for efficient future planning and integration and will now be extended to other areas than the one of the sample exercise.

Rika Takahashi | 16 April 2009On 23 March, the 2008 Nishikawa Award Ceremony was held in Tokyo, and awards were given to three ILC scientists: Yoshihisa Iwashita (Kyoto University), Hitoshi Hayano (KEK) and Yujiro Tajima (Toshiba Co., Ltd).
