About Barry Barish
Barry Barish is the winner of the 2017 Nobel Prize in Physics. He is Distinguished Professor at the University of California, Riverside and Linde Professor, Emeritus at the California Institute of Technology (Caltech). From 2005 to 2013 he was Director of the Global Design Effort and, apart from leading the collaboration to the publication of the ILC's Technical Design Report, contributed more than 300 Director's Corners in the ILC Newsline.

One 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!

The 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.

For 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.

The 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.

The 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.

The 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.

There 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.

SLAC 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.

The particle physics communities worldwide are undertaking strategic planning processes that will set out the course of the field for the coming years. Recent science results, such as the discovery of the Higgs-like particle and the measurement of a relatively large value of theta13, open up exciting future possibilities. In Europe, the process of developing an update to the European Strategy for Particle Physics is under way. The next major step will be an open symposium in Krakow, Poland, from 10 to 12 September, for which a set of linear-collider input documents has been submitted.

The 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.
