ICFA and ILCSC in Melbourne

Fermilab Director
Pier Oddone

The International Linear Collider Steering Committee and the International Committee for Future Accelerators met recently in Melbourne in conjunction with ICHEP2012. Joining us was Lyn Evans, who in June was appointed to be the Linear Collider Director.

In this column I briefly summarize the situation with the ILC and the new organization that brings together the ILC and CLIC efforts. More information can be found in my presentation to ICHEP attendees.

The linear collider effort has received a big boost with the discovery at CERN of a particle likely to be the Higgs boson. There is a lot of activity around the world to understand how far the LHC can go in its study of this particle and what important physics we would require a “Higgs factory” of some sort to study (e.g., this report). A prime candidate for such an accelerator that could be built relatively soon is the International Linear Collider. The ILC is designed to produce a collision energy of 0.5 TeV in the center of mass, with extendability to 1 TeV. If an ILC with an energy lower than 0.5 TeV is chosen as an initial stage, the technical design will need some re-optimization. The 0.5 TeV design, documented in the ILC Technical Design Report and in its Detector Baseline Design, will be available later this year and will be reviewed by an augmented Project Advisory Committee in December.

The TDR and DBD will include the estimated cost for a 0.5-TeV ILC and its associated detectors, although the detector designs are subject to a larger cost uncertainty. An ad-hoc international cost committee assembled by the ILCSC will review the costs in early 2013. By the next meeting of ICFA and the ILCSC in Vancouver in February 2013, both the technical and the cost reviews should be complete.

In terms of the new linear collider organization, the new Linear Collider Board, with oversight of both the ILC and CLIC efforts, will replace the present ILCSC. ICFA appoints members of the board based upon recommendations by representatives from the Americas, Asia and Europe. A nominating committee brings forward candidates from each region and proposes a final slate to ICFA. The LCB will consist of five members from each region plus a chair. You are invited to contact your regional representatives on the nominating committee with your suggestions.

The nominating committee members are:

Americas: Pier Oddone (Fermilab) and William Trischuk (University of Toronto)

Asia: Jie Gao (IHEP, Beijing) and Sachio Komamiya (University of Tokyo)

Europe: Joachim Mnich (DESY) and Manfred Krammer (HEPHY, Vienna and the new ECFA Chair)

The Vancouver meeting will see an overlap meeting between the ILCSC and the new LCB to review the outcomes of both the technical and cost reviews. In the meantime, Lyn Evans will be working to appoint the three associate directors for the ILC, CLIC and physics research. For the latter appointment, Lyn will work directly with the many stakeholders to design the appropriate procedures and management structures.
