Barry Barish | 2 May 2013A key feature of the ILC is that it is a single-pass machine. In contrast to a circular accelerator, where the beam goes around many times, the ILC beams pass through each accelerator element only once, including the interaction point. For the accelerator, this means that for each accelerating module, the machine must be very efficient at transferring wall power into the machine beam, with the added requirement that the final beam must emerge with very low emittance so that it can be focused to the very tiny beam spot required to achieve high luminosity. The ATF-2 at KEK is a special test beam line that has been built to demonstrate the ability to achieve ILC-like namometre beam spots and stabilise them. Recent tests have demonstrated beam spots that are within a factor of two of the ILC design and promise to improve in the future.

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 | 11 October 2012The Technical Design Report will be the culmination and final deliverable for the ILC Global Design Effort. The report will be submitted in near final form to the ILC Program Advisory Committee in November for technical review in December at KEK. The drafting of the report has been under way since last spring. The GDE Executive Committee recently performed a critical review of a second snapshot of the evolving TDR draft.

Barry Barish | 23 August 2012The International Linear Collider Steering Committee (ILCSC) met in Melbourne at ICHEP12 to deal with the completion of its own mission and the initiation of a new organisation to pursue a future linear collider project. The ILC Technical Design Report (TDR) and companion Detailed Baseline Design (DBD) report will represent the final milestone in the mandate for the ILCSC. The ILCSC balanced its planning for receiving, reviewing and rolling-out of these reports over the coming year, with planning for the new organisational structure that will take the next steps toward a global linear collider project.

Barry Barish | 7 July 2011The ILC Program Advisory Committee met at Academia Sinica in Taiwan in May. In addition to their specific recommendations, they again urged development of a strategy for the post-2012 period, following completion of the accelerator Technical Design Report.

Barry Barish | 3 February 2011The most obvious benefit of the seemingly endless series of reviews we undergo comes from the rigours of doing our preparations. But the reviews also serve to validate our work, and perhaps most importantly, the review committees give us good advice in their reports. Last autumn, we had a two-day technical review of the Global Design Effort by the Project Advisory Committee (PAC), a subcommittee of the International Linear Collider Steering Committee (ILCSC). Several recommendations came out of that PAC review that have been quite helpful to us as we prepare to make final decisions on the proposed new baseline configuration for the ILC Technical Design Report (TDR).
