Mike Harrison | 6 January 2011Is there ever a good time to be proposing the creation of a large and complex science facility? Probably not, but at face value we seem to have chosen a particularly inopportune moment to be raising this issue.

Barry Barish | 16 December 2010Today, I describe the second of the proposed change actions, which has been stated as follows: "We propose to change the main linac tunnel configuration to one with only a single, accelerator-enclosure tunnel, thereby eliminating the support equipment tunnel proposed in the Reference Design. We propose to develop and include in the baseline two novel High-Level RF power source and distribution schemes ("KCS" and "DRFS") that are better suited to a single-tunnel solution than the scheme proposed in the RDR. A fall-back to the RDR HLRF Technology can be adopted should the R&D on KCS or DRFS not be considered successful."

Barry Barish | 9 December 2010Today, I will describe the first of those proposed change actions completed in recent weeks. [...] The proposal that I have approved sets the average operating gradient of 31.5 MV/m for operation of the main linac cryomodules, with a spread of up to 20 percent. We believe these parameters are realistic and achievable, but represent challenging goals.

Barry Barish | 4 November 2010One of our most visible and important ILC R&D short-term milestones has been to demonstrate production of ILC superconducting radio frequency cavities with gradient of greater than or equal to 35 megavolts per metre (MV/m) and Q0 = 8x10^9 and 50 percent production yield. [...] Today I announce the successful achievement of that important 2010 milestone.

Peter Garbincius | 28 October 2010This year, the International Workshop on Linear Colliders (IWLC2010), organised by the European Committee for Future Accelerators (ECFA), was noteworthy in that it was the first joint workshop for both ILC and CLIC...

Barry Barish | 21 October 2010[...] The scope of particle physics has grown in recent years to include what we commonly call particle astrophysics, where some of the most important particle physics questions are also of high importance for astrophysics.
