Crabbing in the cavity

| 12 July 2007 What do superconducting cavities and the beach have in common? KEK accelerator physicists can give you the answer: the crab. During the spring operation period of the KEKB accelerator, scientists successfully achieved effective electron-positron collisions in a new cavity. Called the crab cavity, it tilts each bunch sideways so that the bunches collide head-on at the interaction point. This success will allow the KEKB to boost its luminosity, which is already the world’s highest for a B-factory, to an unprecedented level. Crab cavities will also play an important role in achieving high luminosities at other machines, including the International Linear Collider (ILC), upgrades for the Large Hadron Collider (LHC) at CERN, as well as future synchrotron light sources.

China on the walkway towards the ILC

5 April 2007 The Temple of Heaven, a masterpiece of architecture and landscape design in Beijing symbolises the relationship between earth and heaven - the human society and the universe - which stands at the heart of Chinese cosmology. It was the central image on the poster for the 9th ACFA ILC Physics & Detector Workshop and ILC GDE Meeting in February 2007 at IHEP in Beijing, where the ILC reference design and preliminary cost were officially announced. Although the walkway towards the ILC is as long as that in the Temple of Heaven, China is now taking steady steps and making more contributions to the realisation of the ILC. This interest manifests itself in the Chinese scientists' unanimous support for China's participation in the ILC, which has been demonstrated during the Fragrant Mountain Meeting, held at the end of 2006, the expanding collaboration with KEK and other labs worldwide, the ILC GDE Meeting held in Beijing this February, and the various R&D efforts in progress at IHEP and other institutes.

Spotting the Movers and Shakers

| 22 March 2007 Not all vibrations are good. With their 600 nanometres in width and only 6 nanometres in height, the ILC's particle beams could easily be veered off course if parts in the accelerating modules, for example the final focus quadrupole, moved by only a few nanometers. Monitoring and feedback systems will make sure that this doesn't happen, but it's even better to identify weak - moving - points and eliminate them from the very beginning.

ILC Baseline Alternative: The Re-entrant Cavity

| 22 March 2007 ILC R&D on superconducting RF technology is of special importance because it represents our central technology, and it is an area where we are forging the way for future accelerators that will employ this forward-looking technology.

ILC Baseline Alternative: The Marx Modulator

| 1 March 2007 The release of the ILC Reference Design was a very important milestone. Yet, we have emphasised that it is really a snapshot of the ILC design. -- By Barry Barish & Ray Larsen Category: Director's Corner | Tagged: , , , ,

Building and Testing a String of Cryomodules – a Task for S2

| 27 July 2006 An ambitious and crucial goal of the ILC R&D programme is to build and test a string of superconducting RF cryomodules that operate at or near the design gradient. Category: Director's Corner | Tagged: , , ,

Demonstrating the ILC Accelerating Gradient

| 6 July 2006 The centerpiece of the ILC concept is the superconducting RF technology that will be used to accelerate electrons and positrons in the main linac. Category: Director's Corner | Tagged: , , , , , ,

Electron Accelerator R&D for the Energy Frontier

| 20 April 2006 In the context of actively preparing for future electron accelerators and colliders, there will be a two and a half day meeting at LAL, Orsay starting on 15 May. Three European-funded projects (CARE/ELAN, EUROTeV and Euroleap) will meet to review their present activities and to discuss the future. Category: Feature | Tagged:
