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.

Barbara Warmbein | 5 July 2012The LHC experiments are definitely homing in on a Higgs boson in a mass region somewhere around 126 GeV. Further studies and more data from the LHC will tell us more about what it is that they have found, but only a linear collider will be able to tell without prejudice whether it’s a Standard Model Higgs (or not) and determine its mass with a precision down to about 60 MeV. Here’s how.

21 June 2012The International Committee on Future Accelerators (ICFA) has now taken the next significant step towards unification of the ILC Global Design Effort and the Compact Linear Collider organisation. It has appointed CERN's Lyn Evans to be the overall leader for the combined linear collider programmes. ICFA chair Pier Oddone comments.

21 June 2012The international effort to design the world’s next major particle collider has a new leader. On 20 May 2012, the International Committee for Future Accelerators announced the appointment of CERN's Lyn Evans as the new Linear Collider Director. Evans is the first to hold the new position, which will lead the Linear Collider organisation created to bring two existing large-scale linear collider programmes under one governance. He will be based at CERN.
