8 November 2012According to the Standard Model, the mass of the Higgs boson should be enormous. But recent experimental results suggest it’s quite small, indicating that scientists might need to go beyond the Standard Model to explain the new particle.

8 November 2012The original CERN convention, which was drafted nearly 60 years ago, foresaw that the organization should have a role as co-ordinator for European particle physics, as well as operating international accelerator laboratories. Today, this role is more appropriate than ever: the long lead times usually required to prepare and construct facilities and experiments for modern high-energy physics, together with the increased costs for these activities, underlie the need for a general European strategy in the field. So it was natural for CERN Council to initiate the creation of a European Strategy for Particle Physics in June 2005 and to establish dedicated groups for reviewing the scientific status and producing a proposal. They consulted widely with the community, funding agencies and policy makers in preparing the strategy document, which was adopted by Council in July 2006 during a dedicated session in Lisbon.

25 October 2012CERN's newsletter, the CERN Bulletn, reports on progress from CLIC: In early October, the CLIC collaboration published its final Conceptual Design Report. Accompanying it was a strategic summary document that describes a whole new approach to the project: developing the linear e+e− collider in three energy stages. Though CLIC’s future still depends on signs from the LHC, its new staged approach to high-energy electron-positron physics for the post-LHC era is nothing short of convincing.

Barbara Warmbein | 27 September 2012Some 500 particle physicists from Europe and beyond met in Cracow, Poland, in September to kick-start the update of the European Strategy for Particle Physics, an initiative by the CERN Council that sets the European pace for global planning and cooperation on future projects in particle physics around the world. With the recent discovery of the Higgs-like particle at the LHC, a Higgs factory is high up on the wish list.

6 September 2012A recent workshop reviewed the latest experiences with the phenomenon of electron clouds at the LHC and other accelerators. Electron clouds – abundantly generated in accelerator vacuum chambers by residual-gas ionization, photoemission and secondary emission – can affect the operation and performance of hadron and lepton accelerators in a variety of ways. They can induce increases in vacuum pressure, beam instabilities, beam losses, emittance growth, reductions in the beam lifetime or additional heat loads on a (cold) chamber wall.

Qian Pan | 2 August 2012A group of Chinese scientists, headed by Xuejun Jia from the Institute of Physics of the Chinese Academy of Sciences, recently finished the design of the remote handling of the ILC positron target. The target forms part of the positron source and is the place where positrons are produced and then accelerated before they collide with their antiparticles, the electrons.

19 July 2012The International Linear Collider Steering Committee and the International Committee for Future Accelerators met recently in Melbourne in conjunction with ICHEP2012. ICFA chair and Fermilab Director Pier Oddone reports in his Director's Corner in the 17 July issue of Fermilab Today on the new organisation of the linear collider efforts, the timelines and responsibilities. There's also a call for nominees for the new Linear Collider Board.

Rika Takahashi | 12 July 2012On 10 July, governors, industrial leaders, and local officials of Japan’s northeastern area got together to attend a general meeting of the Tohoku Advanced Science and Technology Study Group. In the northeastern part of Japan, or Tohoku, activities towards inviting the ILC to the area has been intensified ever since the ILC was positioned as one of the promising means to recover from the disastrous earthquake occurred last year.
