Director's Corner

The mass production of SRF linac cavities

Today's issue features a Director's Corner from Marc Ross, Project Manager for the Global Design Effort.

Niobium’s superconducting ability recommends it as a metal of choice for ILC accelerating cavities, but it brings challenges to the R&D table. Laboratories and industry alike work to set down the best possible, most cost-effective process for forming niobium into high-performing structures.


From symmetry breaking: Higgs buzz at summer physics conference

Physicists 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.

Power to the cryomodule

by Leah Hesla

Cryomodule 1 at Fermilab is now being powered as a complete, multi-cavity instrument. Scientists will subject it to superconducting radiofrequency tests over the coming weeks.

During the 2011 Europhysics Conference on High-Energy Physics (HEP 2011) press conference, CERN Director General Rolf Heuer ad libbed for the journalists an explanation of the role of the Higgs boson in the standard model of subatomic particles...with his two hands. "We know everything about the Higgs boson except whether it exists," he concluded. View more photos

    Denn gleich zwei Experimente der Physiker liefern Hinweise auf die Existenz des Higgs Bosons: Die LHC-Detektoren “Atlas” und “CMS” registrierten eine ungewöhnliche Häufigkeit von leichteren Teilen im Massebereich von 130 bis 145 Giga-Elektronenvolt (GeV).

    Scientists of the CDF and DZero collaborations at Fermilab continue to increase the sensitivity of their Tevatron experiments to the Higgs particle and narrow the range in which the particle seems to be hiding.

    «Je sais que c’est difficile, mais il faut être patient», assure Rolf Heuer, le directeur général du Cern. Il refuse, comme ses collègues, de sauter le pas et de confirmer la découverte du boson de Higgs, mais son petit sourire en coin trahit tout de même son excitation.

    Der Nachfolger des 27 Kilometer großen Beschleunigerrings könnte den Namen “CLIC” tragen. Das Konzept dazu wurde auf der Europäischen Teilchenphysik-Konferenz in Grenoble vorgestellt.

    A new result from Fermilab’s DZero experiment was announced Saturday at the European Physical Society conference in Grenoble, France, studying the production of the top quark and its antimatter counterpart, the antitop quark, in proton-antiproton collisions.

    When its experiments started in earnest earlier this year, many scientists hoped that the world’s most powerful collider would turn up new particles, additional dimensions and perhaps even a small black hole or two. But beyond a handful of unusual events, the latest data from the Large Hadron Collider (LHC) are frustratingly ordinary.

    The Higgs boson is still missing – but perhaps we should be more worried about what else the Large Hadron Collider hasn’t found yet.

    Newly released observations of the top quark — the heaviest of all known fundamental particles — could topple the standard model of particle physics. Data from collisions at the Tevatron particle accelerator at Fermilab in Batavia, Illinois, hint that some of the top quark’s interactions are governed by an as-yet unknown force, communicated by a hypothetical particle called the top gluon.

    …Finding the tell-tale sign of a Higgs boson among all other particle signatures is like searching for a drop of ink in an ocean. Only if the accelerators produce more and more collisions do scientists stand a chance of finding enough evidence for the Higgs particle.

    For now, physicists are only willing to call them ‘excess events’, but fresh data from two experiments at the Large Hadron Collider (LHC) are hinting at something unusual — and it could be the most sought-after particle in all of physics.

    Physicists working with the world’s largest atom smasher may have spotted evidence of the long-sought Higgs boson. At least that’s the unofficial result that has the 800 physicists here for the biannual Europhysics Conference on High-Energy Physics abuzz.

    The latest data from experiments at the Large Hadron Collider (LHC) leave significantly less room for the Higgs boson to hide – that is the take-home message from the Europhysics Conference of High-Energy Physics in Grenoble, France.
