Polishing the safety standards

Sawabe explaining the EP machine.
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.

In Memoriam
Sad news for the ILC community
Vincent Lepeltier

Vincent Lepeltier, our good colleague and friend, suddenly passed away last week, a few days after the Sendai meeting, leaving us full of pain and sadness. We will miss very deeply both his professional and human qualities.

For more than twenty years Vincent was a world expert in gaseous detectors, especially of Time Projection Chambers (TPC) who was based at LAL, Orsay, France. After having worked on all aspects of the DELPHI TPC, and especially its drift velocity monitoring, crucial to obtain a good longitudinal resolution, and a very successful participation to the FFTB experiment at SLAC in the early 1990s, he led in 1996 the small LAL-LBNL-Cincinnati group that designed and built the miniTPC for PEP-II commissioning.

Greatest experiment ever in particle physics nears countdown
If things go according to plan, the greatest experiment in the history of particle physics could unveil a sub-atomic component, the Higgs Boson, which is so tantalising that it has been called "the God Particle."

Belle experiment observes a difference in direct CP-asymmetry between charged and neutral B meson decays
Although it is susceptible to strong interaction effects, this difference could be an indication of a new source of CP violation that is needed to explain the matter-dominated Universe.

Director's Corner
The next step towards the ILC — building a truly global team
Today's issue features a Director's Corner from Marc Ross, Project Manager for the Global Design Effort.

At the Tata Institute of Fundamental Research in Mumbai, with Prof. A. Gurtu and Prof. R.G. Pillay.
It has been roughly a year since the completion of the Reference Design Report (RDR) and the creation of a project-oriented design effort. It is reasonable, therefore, to look broadly over our accomplishments and the direction in which we are heading.

Getting behind the wheel

As the ILC positron source community prepares for its next collaboration meeting at DESY in Zeuthen from 7 to 9 April, physicists and engineers from the University of Liverpool, Daresbury Laboratory and the Cockcroft Institute in the UK are putting the finishing touches to a first prototype of a positron production target for use in the ILC positron source. The titanium alloy spoked wheel is one metre in diameter and designed to rotate at speeds of up to 2000 rpm in magnetic fields of up to 1.5 Tesla. Once the magnet and safety guarding have been moved in place, the prototype will be used to explore how the real target wheel will interact with the magnetic fields that will be used to capture and focus emitted positrons.
