Barry Barish | 21 November 2012One of the most important goals of the Global Design Effort has been to demonstrate that high-gradient cavities can be reliably produced in industry. We established two gradient goals: to produce cavities qualified at 35 Megavolts per metre (MV/m) in vertical tests and to demonstrate that an average gradient of 31.5 MV/m is achievable for ILC cryomodules. Furthermore, we set a goal of producing these high-gradient cavities in industry with 50% yield by 2010 and 90% yield by the end of 2012. We have recently achieved these ambitious goals!

Barry Barish | 8 November 2012The Institute of Electrical and Electronics Engineers (IEEE) held a “Special Linear Collider Event” as part of their 2012 Nuclear Science Symposium and Medical Imaging Conference at Anaheim, California. The special event, held on 29 and 30 October, came on the heels of the discovery of a Higgs-like particle at the LHC at CERN this summer and included an array of leaders in the field. There were presentations on the International Linear Collider (ILC) and Compact Linear Collider (CLIC) accelerators as well as detector concepts, the potential impact of the LC technologies for industrial applications and a forum discussion about future LC perspectives.

Barry Barish | 1 November 2012For several years, 2012 has been anticipated as the time when progress in the field of high energy physics would enable us to clarify the priorities for future planning. The interesting LCWS12 workshop at the University of Texas brought together the elements for such planning, if not a plan. There were reports on the discovery of the Higgs-like particle at the LHC and how that might be pursued in a linear collider; there were reports on the future planning processes that are underway in Europe, Japan and the U.S. and there were reports on the progress in developing the ILC Technical Design and CLIC Conceptual Design as well as how a staged approach might be responsive to the LHC discovery.

Toshiaki Tauchi | 25 October 2012KEK's Accelerator Test facility (ATF) is up again after its summer shutdown. After several improvements to beams size monitors, multi-ole magnets and the organisation structure, the international team is looking forward to squeezing the beam size further and further towards the 37 nanometres required for the ILC.

Barry Barish | 18 October 2012The S1-Global experiment was conceived to demonstrate the radiofrequency (RF) operation of an ILC cryomodule with an average accelerating gradient of 31.5 MV/metre. The project to build a segment of a superconducting linac system and test the string of superconducting RF cavities was carried out at KEK through a global collaboration. This experiment provided a significant and successful demonstration of the operation of eight nine-cell superconducting cavities and associated hardware components with components provided from laboratories around the world.

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 | 4 October 2012The High Energy Physics Advisory Panel met on 27 and 28 August in Rockville, Maryland, US. A central focus of this meeting was the proposed Fermilab Long Baseline Neutrino Experiment. The meeting included presentations on the physics potential, the reconfiguration options in response to Department of Energy guidance, and perspectives from Fermilab, the collaboration and the DOE.

Nick Walker | 27 September 2012GDE Project Manager Nick Walker reports from a focused, positive and lively meeting in Cracow and the impact the discussions can have on the ILC. Would a staged approach - starting at 250 GeV to make the ILC a Higgs factory and ramping up to 500 GeV later - make for a cheaper machine? Where are the potential savings, and how long would it take to build an ILC Higgs factory?

Barry Barish | 20 September 2012There are no official proposals for where the ILC could be located. Rather, our approach has been to develop an ILC design compatible with three “sample” sites that have different characteristics. In this process, we have by no means ruled out the possibility of housing the ILC in a shallow site, even though all three of our sample sites are deep underground. A new shallow site possibility has recently been suggested in Hanford, Washington in the US.

Barry Barish | 13 September 2012SLAC has had a remarkable first 50 years, which were celebrated in a special event this past month. Although the theme of that event focused on the next 50 years, the achievements of the past inform the future plans and prospects. In that regard, the physics achievements of SLAC were duly noted at the event because the American Physical Society named it an APS Historic Site and awarded the lab a plaque.
