With stable beams regularly circulating and colliding in the LHC, we have started the physics programme at 7 TeV. At a recent workshop in Italy, participants had the chance to take stock of what lies in store for the LHC's first physics run.

Geneva, 30 March 2010. Beams collided at 7 TeV in the LHC at 13:06 CEST, marking the start of the LHC research programme. Particle physicists around the world are looking forward to a potentially rich harvest of new physics as the LHC begins its first long run at an energy three and a half times higher than previously achieved at a particle accelerator.

On 30 March, the Beijing meeting ended on a high note. Nearly 300 participants, together with local and scientific organising committees, worked hard to make this meeting a success while at the same time, in Geneva, the Large Hadron Collider (LHC) opened a new page in particle physics history. “It's a day of celebration,” concluded Jon Bagger, Chair of the International Linear Collider Steering Committee, “the day where we start lighting the Terascale.” The ILC will build on LHC discoveries, and to make this project a reality the whole ILC community gathered in Beijing. There were deep discussions between the accelerator and the physics and detectors experts of a level that has never happened before in such a global meeting. All use each others' feedback during the workshop to draw up what will be their plans for the next two years, when in 2012 they deliver the Technical Design Report (for the machine) and the Detailed Baseline Design of the detectors reports. A lot of reviews, R&D and studies are still to be done but participants now leave Beijing with clear ideas on what path to follow to achieve them.

Yesterday the science news media and twitterverse were abuzz following a BBC News article announcing “LHC to shut down for a year to address design faults.” Readers – and the news outlets that frantically re-reported the BBC article – assumed that CERN had found a new problem with the LHC and announced an imminent shutdown. Neither is the case. Here, we join our fellow science writers and bloggers in setting the record straight about the LHC’s next long shutdown.

With the quiet, deft manner of a jeweler showing his wares, physicist Cai Xiao opened a black box that, in a James Bond movie, might hold a stash of diamonds. This one held something every bit as precious. Inside lay a small, green circuit board topped with three shining silver strips: a silicon detector.

In a provocative section of a talk at the American Physical Society meeting in Washington, DC, yesterday, theorist Matthew Strassler from Rutgers University challenged particle theorists to not be too simple in their analyses. Most people would probably not claim that theoretical particle physics is too simple, but Strassler argued that nature is likely to be even more complicated than physicists expect. And if theorists only properly examine the simplest classes of models, where simple is a relative term, they might be led astray in interpreting future Large Hadron Collider data.

The particle physics community is accustomed to global collaboration, and here at KEK, one of those collaborations has just begun on a core technology for the International Linear Collider (ILC), the superconducting accelerating system.

Last week, the Chamonix workshop once again proved its worth as a place where all the stakeholders in the LHC can come together, take difficult decisions and reach a consensus on important issues for the future of particle physics. The most important decision we reached last week is to run the LHC for 18 to 24 months at a collision energy of 7 TeV (3.5 TeV per beam). After that, we’ll go into a long shutdown in which we’ll do all the necessary work to allow us to reach the LHC’s design collision energy of 14 TeV for the next run. This means that when beams go back into the LHC later this month, we’ll be entering the longest phase of accelerator operation in CERN’s history, scheduled to take us into summer or autumn 2011.

MEDFORD, NY — Today, the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Advanced Energy Systems, Inc. of Medford, N.Y. (AES) celebrated the opening of a new hi-tech facility at the AES site that will produce crucial components used in particle accelerators around the world. Brookhaven Science Associates, which manages Brookhaven Lab for DOE, purchased equipment worth approximately $2 million as its contribution to the facility. AES invested in the infrastructure improvements it needed to expand its operations, assisted by a $200,000 grant from the Empire State Development Corporation.

Last month the KEK facility in Japan hosted the ninth Project Meeting for the Accelerator Test Facility 2, or ATF2, and a few SLAC staff traveled overseas to participate. The group reviewed progress made in 2009, plans for 2010, and the possibility of extended studies beyond the primary ATF2 goals in 2011, 2012 and beyond. A total of 44 collaborators, including 28 from outside Japan, discussed the technical progress of the ATF2, which began commissioning in December of 2008. The program also covered the future of the project in the face of some major cuts to science funding bodies by the Japanese government.
