Approximately 100 participants met at DESY on 15-17 February for two and a half days of intense discussions at the EUDET Kick-Off meeting. EUDET is a European Integrated Infrastructure Initiative aiming at the improvement and development of infrastructures for ILC detector developments. Twenty-two participating institutes and 21 associated institutes join forces in a project with a budget of approximately 21.5 million Euros, of which the European Commission contributes 7 million Euros. The project started officially six weeks before the Kick-off meeting on 1 January 2006 and will run for four years. The Kick-off meeting was the first opportunity for the whole collaboration to come together and discuss future plans in detail.

The rise and fall times of the pulses in the injection kickers influence the minimum circumference of the damping rings in the International Linear Collider. The Baseline Configuration Document features 6 km rings which will require pulsers to feed 50 ohm stripline kickers. The 5 kV (kilovolt) pulses must have 6 ns (nanosecond) rise and fall times, and a total duration of approximately 14 ns. Operating in a burst mode, every 5 seconds the kicker will have a 3 MHz (megahertz) burst that lasts 1 ms (millisecond). The combination of the electric component from the 5 kV voltage pulse and the magnetic component from the accompanying 100 A (amp) current pulse will deflect the electron and positron beams. The temporal specification of the kicker pulse presents a challenge to the existing generation of pulser technology.

The first day of the 2006 Chinese New Year was on 29 January 2006. Following the 6 January announcement that an international research collaboration observed a resonant state at the upgraded Beijing Spectrometer (BESII), scientists celebrated very good news at this important Chinese festival. The discovery, which was reported in the 31 December 2005 issue of the Physical Review Letters, has aroused broad interest from the global high-energy physics community (detailed report). We believe that more interesting discoveries could be found in BES-III of BEPC-II, which is under construction at IHEP, Beijing, China.

The International Linear Collider (ILC) interaction region beam sizes and component position stability requirements will be as small as a few nanometers. Making a head-on collision with a few nanometers beams, each beam travelling across some 20 km in the linear accelerator, is a bit like colliding two baseballs -- one thrown from earth and the other from Saturn! It is important for the ongoing ILC design effort to demonstrate that these tolerances can be achieved -- ideally using a beam-based stability measurement.

The start of the European Union funded EUDET project is marked by a Kick-off Meeting at DESY on 15 to 17 February, 2006. The project assembles 31 European institutes and 20 international associates to prepare infrastructures to allow for ILC detector R&D with larger prototypes.

After the Frascati meeting, Asian institutes started seeking ways to collaborate on ILC R&D towards Reference Design Report (RDR). About 30 researchers from Korea, China and Japan met at IHEP, Beijing on 16 January. Indian members were not able to attend, therefore this meeting was dubbed as "ILC-Beijing", not "ILC-Asia".

As the Baseline Configuration Document (BCD) becomes semi-stabilized, the canonical mission of the Change Control Board (CCB) is to act as a body to make decisions on important changes to the baseline configuration, if and when necessary. Nobu Toge is assigned to chair this board.

Traditional circular accelerators around , like LEP and KEKB, accelerate electrons and positrons in rings into opposite directions respectively. A bunch of electrons and another bunch of positrons encounter each other many times in a ring, and consequently have many chances to collide. In the ILC on the other hand, electrons and positrons are accelerated oppositely, meeting only once at the collision point. No consolation match is allowed.
