Something unwanted lurks within accelerator beam pipes around the world: stray electrons. This haze of electrons interacts with positron and proton beams, often causing distortion. Previous tests showed that an insert designed by SLAC researchers works well to capture stray electrons in an environment with no magnetic field. Now, recent tests carried out at the Japanese accelerator facility KEK confirm that a new insert can reduce this electron cloud effect in a magnetic field.

A new beamline for R&D toward nano-meter electron beam has started operation at KEK's Accelerator Test Facility - ATF. This new beamline, called ATF2, is an extension of ATF, and the focus of the research there will be on establishing the technologies for creation and control of a nano-meter-sized electron beam.

April is the best time to visit Japan – nice and warm weather, cherry blossoms and lively atmosphere of starting a new fiscal year – and of course, TILC09! A worldwide meeting of physicists on the ILC accelerator, experiments and theory to further the ILC's Technical Design Phase.

This week SLAC National Accelerator Laboratory moves one step closer to producing an innovative new piece of the International Linear Collider. The first-generation model of a new design for equipment that helps power the accelerator is moving from the SLAC Power Conversion Department to End Station B, where it will undergo long-term testing.

Nearly a half-century ago, researchers at Stanford University began investigating superconducting RF (SRF) acceleration. They would not have been surprised to learn that by 1994, SRF had come into large-scale use in Jefferson Lab's Continuous Electron Beam Accelerator Facility, or that by 2008 it was planned as the enormous, ultra-cold, dynamic-but-delicate heart of the proposed International Linear Collider (ILC). Nor would they be surprised to learn that this complex technology's challenges nevertheless continue to vex accelerator builders. In my view, it's time for the accelerator community to go back to where the pioneers at Stanford began, hit the pause button, and take a careful look at more than four decades of SRF R&D.

Plans are taking shape to form a new group to coordinate and stimulate R&D on monolithic and vertically integrated pixel detectors for scientific applications in high-energy physics and beyond. In a joint message, the directorates of CERN, KEK and Fermilab have offered their support. They suggested the formation of a regionally balanced coordination board to take this forward. From discussions in recent reviews and workshops, we think there is an opportunity for the many efforts underway worldwide to benefit a larger community. We already have strong collaborations for the development of vertical integration and monolithic active pixel sensors (MAPS). The new world-wide effort would build upon the existing collaborations and open the technology developments to other scientific areas. We will discuss how best to achieve this at upcoming meetings. Our suggestions will then be comunicated to the directorates of CERN, KEK and Fermilab.

"Particle physics is at a crossroads," said Chairperson Albrecht Wagner of the International Committee for Future Accelerators, in the opening moments of the ninth ICFA Seminar last Tuesday in Kavli Auditorium. "The Standard Model stands triumphant," Wagner said, "yet incomplete."

It feels like the real accelerator tunnel, but it’s only building 71 at DESY in Hamburg. It’s basically a tube made of concrete, 51 metres long and 5.20 metres in diameter. One accelerator module hangs from the top of the tube, water pipes, cable trays and ventilation ducts are installed and other accelerator parts stand around on the tunnel floor. All these are dummies, some even made of wood, but they are life-size dummies in building 71: the European XFEL mock-up tunnel.

With the activation of the LHC, or Large Hadron Collider, some particle physicists are now looking forward to the next big machine. For many, that's the International Linear Collider. The ILC aims to break new ground in particle physics by slamming a beam of electrons into a beam of the electron's alter ego: the positron.
