Leah Hesla | 15 September 2011Resolved that pictures of particle jets don’t have to be fuzzy or gnarled, scientists developed the particle flow algorithm, a paradigm for effectively teasing out each particle’s energy from another’s. To make it work, researchers expanded the tracking capabilities of the detector model, enabling it to measure energies with higher precision.

Rika Takahashi | 25 August 2011The superconducting magnet PCMAG came back to KEK on 10 August after four years of use in an experiment at the DESY test beam facility. PCMAG, which stands for persistent-current superconducting magnet, will be upgraded to be a coolant-free magnet.

11 August 2011How can a low-energy experiment like SLAC’s PEP II B Factory, originally built to investigate differences between matter and antimatter and no longer even taking data, compete with a monster matter masher like the LHC that was built, in a large part, to find the Higgs?

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.
