Demonstrating the ILC final focus parameters

| 2 May 2013 A 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. Category: Director's Corner | Tagged: , , , ,

Dream for humankind

| 18 April 2013 On 27 March, LCC Director Lyn Evans paid a courtesy visit to Japan’s Prime Minister Shinzo Abe, who said a linear collider was a dream for humankind. Deputy Director Hitoshi Murayama also attended the meeting and explains why this moment was very special for him. Category: Director's Corner | Tagged: , , ,

Le roi est mort, vive le roi ! (*)

| 4 April 2013 The 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.

Forming a united front of the LC physics and detector community

| 21 March 2013 Recently appointed Associate Director for Physics & Detectors in the new Linear Collider structure, Hitoshi Yamoto discusses his mandate and solicits inputs from the linear collider community. Category: Director's Corner | Tagged: , , , ,

ILC TDR cost under review

| 7 March 2013 The 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.

From technology to diplomacy

| 7 March 2013 On 21 February the International Linear Collider Steering Committee (ILCSC) handed over to the new linear collider structure. The Linear Colllider Board (LCB), chaired by Sachio Komamiya, replaces ILCSC, and the Linear Collider Collaboration (LCC) replaces GDE and the groups working on physics and detectors for both the ILC and CLIC. The LCC of course also includes the CLIC study. Linear Collider Director Lyn Evans looks ahead. Category: Director's Corner | Tagged: , , , , , ,

A time of transition, or When men and mountains meet

and | 21 February 2013 Today 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. Category: Director's Corner | Tagged: , , , ,

TDR review season is underway

| 7 February 2013 The 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.

2013: The year of the snake or the “What if?”

| 24 January 2013 Ewan Paterson, member of the Global Design Effort Executive Committee, weighs the options that new year, new collaboration and TechnicalDesign Report bring. Will 2013 be the year of the "What if"? Category: Director's Corner | Tagged: , , ,

Happy New Year! Reflections on 2012

| 10 January 2013 Last 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.
