Setting the stages for shorter bunches
|
One of the busiest places in the ILC design is the central region. It’s where it all happens: the beams get squeezed and focused and kicked into collision and out comes physics. To make sure that everything works to perfection and to reach consensus on the design, the central region has just undergone a technical baseline review, along with areas like the connection between damping ring and main linac. One of the core decisions for the latter: a two-stage bunch compressor for shorter beams.
FeatureFrom symmetry breaking: Favored Higgs hiding spot remains after most complete search yet
Almost a year of work, more than 50 meetings and plenty of diplomacy went into calculating the LHC experiments’ first combination of Higgs search results. The study, made public on 18 November, eliminates several hints the individual experiments saw in previous analyses but leaves in play the favored mass range for the Higgs boson, between 114 and 141 GeV. ATLAS and CMS ruled out at a 95 percent confidence level a Higgs boson with a mass between 141 and 476 GeV. |
Director's Corner“The GDE must write” – The first steps to the ILC Technical Design ReportThis week's issue features a Director's Corner from Nick Walker, Project Manager for the Global Design Effort.
ILC Project Manager Nick Walker describes the several books that will form up the ILC Technical Design Report. This ambitious document, planned to be released by Spring 2013, should reflect the enormous job led by the Global Design Effort over the last years.

Illinois Accelerator Research CenterThe Illinois Accelerator Research Center, or IARC, will provide a state-of-the-art facility for accelerator research, education and industrialisation. Located on the Fermilab campus, near Chicago in the US, the new building will house 42,000 square feet of offices, technical and educational space for scientists and engineers from Fermilab, Argonne, local universities and industrial partners.
