Barry Barish | 20 January 2011The ILC is still very much a dream and the path to a real project remains highly uncertain, even though the scientific case is as strong as ever and we continue to meet all our highest priority goals. Hopefully, the world political and economic climate will improve before too long and there will once again be receptiveness to major investments in large-scale basic science projects. It is hard to imagine that we have seen the last of such projects; therefore our strategy is to be as prepared as possible to make a strong proposal for a linear collider when the time is right. Keeping that ultimate goal in mind, how are we doing and what did we accomplish in 2010? In fact, in my opinion, last year was a banner year for the Global Design Effort!

Barry Barish | 13 January 2011Happy New Year! This is my first column of 2011 and I am very pleased to begin the year by reporting on the significant new investment in particle physics by the Italian government. The Italian Ministry for Education, University and Research has announced the funding of the proposed €400-million Super B project of the Italian National Institute of Nuclear Physics (INFN). The present plan is to site the machine at or near the Frascati Laboratory and to reuse magnets and other apparatuses from the PEP-II accelerator and the BABAR detector at SLAC in the US, both keeping costs down and enabling a rapid construction schedule, perhaps as short as five years.

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 | 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.
