Research Director's Report
We call for Expressions of Interest

Resarch Director Sakue Yamada requests Expressions of Interest.
Several steps have been taken since my last report in February. At the ACFA-GDE joint workshop in Sendai held two weeks ago, I reported on the latest development in some detail and exchanged opinions with participating colleagues.

First good news: the International Detector Advisory Group (IDAG) membership list is now complete. The group will give advice on the validation process of Letters of Intent and detector R&D. The members include experienced experimentalists, active phenomenology theorists and ILC accelerator experts. They are: Michael Danilov (ITEP), Michel Davier (LAL/Paris-Sud University), Abdelhak Djouadi (Paris-Sud University), Eckhard Elsen (DESY), Paul Grannis (SUNY at Stony Brook), Rohini Godbole (Indian Institute of Science), Dan Green (FNAL), JoAnne Hewett (SLAC), Tom Himel (SLAC), Dean Karlen (Victoria University), Sun-Kee Kim (Seoul National University), Tomio Kobayashi (Tokyo University), Weiguo Li (IHEP), Richard Nickerson (Oxford University) and Nobukazu Toge (KEK). The group is chaired by Michel Davier.

A different kind of Terascale

Some members of the UK team (Jamie Ballin, Matt Noy, Anne-Marie Magnan, Yoshinari Mikami and Marcel Stanitzki) presenting their data acquisition board with sensor after a successful run in the test beam at DESY.
Have you ever used a map to find an electron? Not possible, you say? Think again. Spell it slightly differently – MAPS – put it into an electromagnetic calorimeter, and you may well be able to track an electron in a calorimeter and see the single electrons in a particle shower. With a spatial granularity of 50 microns square– that’s 50 thousandths of a millimetre – a potential sensor, called MAPS or monolithic active pixel sensor, for an ILC detector’s digital electromagnetic calorimeter could be an efficient alternative to existing silicon technology. A UK-based group is currently evaluating how suitable this technology is for a calorimeter optimised for particle flow, with a view to seeing how efficient, reliable and cost-effective it is.

Letter: Difference in direct charge-parity violation between charged and neutral B meson decays
... Although it is susceptible to strong interaction effects that need further clarification, this large deviation in direct CP violation between charged and neutral B meson decays could be an indication of new sources of CP violation—which would help to explain the dominance of matter in the Universe.

Director's Corner
Congratulations, it's a PAC - scientific oversight for the GDE

Group photo of the ILCSC taken at their last meeting at DESY
The International Linear Collider Steering Committee (ILCSC) of ICFA met at DESY in Hamburg on 11 February – their first meeting since October last year. The ILCSC is responsible for creating the Global Design Effort and for appointing me as GDE director, and it provides the continued scientific oversight for our efforts. The ILCSC Memorandum of Understanding is the official collaborative agreement for the countries and laboratories involved in R&D and design towards the ILC. At their most recent meeting at DESY, the ILCSC reviewed our revised plans for the Technical Design Phase, taking into account the funding reductions from the UK and US. This important meeting established the foundation for our future work in the GDE and for the experimental community as they also enter into a new phase of their activities, calling for Expressions of Interest and Letters of Intent.

Japanese writing session at IWAA

Alignment study is the crucial part for the accelerator design. At the 10th International Workshop for accelerator Alignment (IWAA) held at KEK in February, scientists also learned Japanese style of alignment of words: Shuji, Japanese calligraphy. This calligraphy, done by a European scientists, says 'Onko-Chishin', which means 'Find new wisdom through old things'.
