The twitter chatter over CERN's Higgs news on Tuesday was nonstop, enough to prompt New Scientist to remind us, in a tweet about the Durban conference, "it's not ALL about the #Higgs you know".

A delegation from the prefectures Fukuoka and Saga on the Japanese island Kyushu visited two European labs, CERN and DESY, last week to learn about existing research infrastructures and the labs' experiences with management, administration, local communication and a whole lot more. The region is one of two possible Japanese sites for the ILC, and the delegation, consisting of four members of the Fukuoka/Saga ILC planning committee, wanted to establish a dialogue with the European labs to exchange ideas and information. At DESY, they heard about DESY regional cooperation, socioeconomic impacts, innovation and technology transfer, outreach with local communities and of course DESY and the ILC. They also visited some facilities on campus, including the new accelerator module test hall for the European X-Ray Free-Electron laser XFEL, pictured here.

The Compact Linear Collider (CLIC) team at CERN are investigating the potential of a new kind of particle accelerator, and to help them they are simulating their designs using grid resources, such the UK computing grid for particle physics, GridPP. They build a customised version of the DIRAC system, called ILCDirac, a grid environment for both CLIC and similar experiments which is aimed at benefitting the entire linear collider community. Read the full article in International Science Grid This Week This is an edited version of an article that first appeared on the GridPP website

The 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.

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.

At the Superconducting Test Facility (STF) at KEK, Japan, the construction of the injector cryomodule equipped with two ILC-type nine-cell cavities has begun for the Quantum Beam experiment. The cavity string has been brought out of the clean room, ready for tuner installation. The gas return pipe is being readied to be placed in the cold-mass assembly framework.

Last month, a true tabletop electron accelerator was shown to the public for the first time during the CNRS exhibition Entrée en matière in Trocadéro's gardens in Paris, France. This model was built to serve as a general introduction to the understanding of the principles underlying accelerator operations in general and more specifically colliders. The public can actually see and manipulate the controls and therefore easily grasp what is happening. The model is a small replica of the Orsay storage ring (Anneau de Collision d’Orsay, ACO) at LAL. ACO was in service as a collider from 1965 to 1980 with an energy of 500 MeV for each beam. The real accelerator is now a museum, listed on the French heritage register. Learn more (in French) about the model called "Electrons' dance".

The most ambitious future application under study is for the International Linear Collider (ILC), a 500 GeV superconducting linear accelerator. It will require 16 km of superconducting cavities operating at gradients of 31.5 MV/m. Intense research is underway to reach a high yield for high gradients: 30–40 MV/m. New vendors for niobium, for cavities and for associated components are being developed around the world.
