Mike Harrison | 4 April 2013The problems of succession to the throne have bedeviled society throughout the ages. For centuries the European approach seemed to involve bloodshed ranging from the personal to the national level. The recent transfer of power in the linear collider world might not have been violent, but it still faces the eternal question of “OK, so where do we go from here?” Here are some thoughts on the ILC programme.

Barry Barish | 7 March 2013The final deliverable of the Global Design Effort, the ILC Technical Design Report, was completed and submitted in draft form to the International Linear Collider Steering Committee in November 2012. Following a successful technical review of the design in December, an International Cost Review was conducted in February of the value estimate. The cost review validated the TDR value estimates, and pointed out other costing efforts that will be needed as the ILC becomes a site-specific construction project.

Barry Barish and Lyn Evans | 21 February 2013Today represents a crossroads in the global efforts towards a linear collider. We are officially making the transition from the International Linear Collider Steering Committee and Global Design Efforts to the new Linear Collider Board and Linear Collider Collaboration that will coordinate the next phase of the global R&D towards a high-energy electron-positron collider to complement the LHC. GDE Director Barry Barish and LCC Director Lyn Evans share their vision in a joint Director’s Corner.

Barry Barish | 7 February 2013The draft of the ILC Technical Design Report (TDR) was completed last November and submitted for review. On 13 and 14 December, the TDR underwent a technical review at KEK by an augmented ILCSC Program Advisory Committee. The review report endorses the technical design we have presented and recommends “no changes in the TDR.” The report does identify areas and items to address in the future.

Barry Barish | 10 January 2013Last year was an especially exciting year for particle physics with the discovery of a 126-GeV particle that appears to be the long-sought Higgs boson. This event is likely to be the most important discovery in decades: the observation of a new kind of particle that signals the mechanism for creating mass in the universe. These impressive early results already point to future directions for the LHC, and more broadly for particle physics. In fact, closer to home, this discovery is providing strong motivation for a Japanese initiative for a staged approach to the ILC, beginning with a ~250 GeV Higgs factory, with the capability of increasing the energy in the longer term.

Barry Barish | 20 December 2012One of the key objectives of the ILC R&D programme during the Technical Design Phase has been to characterise electron cloud effects in an ILC-like low-emittance positron damping ring and to test proposed mitigation techniques. The centerpiece of our efforts has been the CesrTA programme that involved reconfiguring it as an ILC-like low emittance ring and instrumenting it to carry out these studies. CesrTA has been a highly successful experimental programme, leading to reliable mitigation strategies for the ILC positron damping rings.

Steinar Stapnes | 6 December 2012It is reporting season: the ILC community is producing the Technical Design Report that also includes the Detector Baseline Design reports, and the CLIC collaboration with associated Detector and Physics studies group have been hard at work completing the CLIC Conceptual Design Report (CDR). The documentation probably surpasses by a large amount - in scope, details and volume - what is normally called a CDR for a project, but then again, there is a lot of work to report on.
