Getting the interaction point right

A model of displacements within the detector (here SiD) if it was lifted by its left front and back right corners.
Like the rest of society, the ILC community is split into two categories: the early risers and the night owls. Workshop organiser Andrei Seryi considers himself a night owl. Nevertheless he is up at 5 and in the lab at 6 am many days per week these weeks, holding phone meetings with the rest of the world. Some hundred specialists are already extremely busy preparing for the ILC interaction region engineering design workshop, or IRENG07, at SLAC in September. Their goal: to have all the facts together to take important decisions for the ILCís interaction region.

Construction of Fermilabís ILC Test Area moves forward

Getting ready to house the first crymodules: Fermilab's ILCTA.
As ILC research and development efforts ramp up around the world, Fermilab is preparing to make an important contribution. Engineers and technicians at the labís new ILC Test Area (ILCTA) have worked hard all summer creating a state-of-the-art cryomodule test facility, and the infrastructure is almost complete.

Director's Corner
Physics of the top quark
This week I am participating in the XXIII International Symposium on Lepton and Photon Interactions at High Energy (LP07) in Daegu, Korea from 13 to 18 August 2007.

Robin Erbacher keeping very good company.
The Lepton-Photon Symposium is held every other year and is sponsored by the International Union for Physics and Applied Physics (IUPAP). It is the major international particle physics conference in odd-numbered years and maintains a very successful format of all-plenary rapporteur talks that review the current status of a broad range of topics at the forefront of particle physics research.

This year's meeting got off to a good start, as the very first scientific talk was on the physics of the top quark. In a fast moving field like particle physics, we often joke that this year's discovery becomes next year's background as we quickly move on to new science goals. On the other hand, a new discovery can just as well open up promising new areas of research. Here at LP07, Robin Erbacher of University of California at Davis presented a talk packed with results on “Top Quark Properties” that illustrates the richness and potential of pursing studies of our heaviest quark.
