Leah Hesla | 4 August 2011A stable particle beam needs a trouble-free path on its way to high energies, and that means providing it with a smooth gradient to ascend. A team of scientists at Fermilab has arrived at a way to control accelerating cavities so they can give particle beams exactly that – a tilt-free path to collision.

28 July 2011Physicists could be on their way to discovering the Higgs boson, if it exists, by next year. Scientists in two experiments at the Large Hadron Collider pleasantly surprised attendees at the European Physical Society conference this afternoon by both showing small hints of what could be the prized particle in the same area.

Rika Takahashi | 14 July 2011Worrying about blemishes on the skin is not just an issue for people who pursue personal physical beauty, but also for accelerator scientists. Scientists and engineers at KEK have found a way to deal with unwanted stains on the inner surface of superconducting cavities, which might be one of the causes of performance limitation.

7 July 2011I got involved in particle accelerators as a graduate student because I wanted to work in an area that had the potential to have a positive impact on people’s lives in 10 to 20 years. Near the end of my PhD studies, I attended a talk by Herman Winick, who introduced the audience to synchrotron radiation sources and the research going on at the SPEAR ring at what is now the Stanford Synchrotron Radiation Lightsource, SSRL.
Ties Behnke (DESY) and Roman Pöschl (CNRS/LAL) | 30 June 2011With the publication of the Detailed Baseline Design Report in their sights, members of the ILD collaboration work diligently to form realisable models of their detector, ones that take into account both their physics simulations and the nuts and bolts of engineering designs.

Leah Hesla | 30 June 2011Learning to stabilise a particle beam of longer pulses such as those needed for the ILC requires diligence, patience and practice. ILC and FLASH scientists share the fruits of all three at the recent workshop on long bunch trains.

Leah Hesla | 23 June 2011Linear collider collaborators are on board with the use of two platforms to move the ILC’s two colossal detectors in and out of the particle beamline. Now they work to design them so the detectors' rides are as smooth as possible.

Leah Hesla | 9 June 2011Last month Jefferson Lab, instrumental in developing SCRF technology for the ILC, took a critical step in a five-year upgrade of its CEBAF accelerator. Once complete, the machine will be able to accelerate electron beams to energies of up to 12 GeV, allowing researchers to chart, with ever greater depth and resolution, the map of the nucleon.
