The ILC physics programme is based on building two complementary detectors that will share beam time. The value of having two detectors with different designs, technologies, collaborations and emphasis has proven to be a very effective way to exploit the science. For the ILC, we propose using a push-pull concept to cost-effectively share the beam between two detectors.

A major accomplishment last year was the evaluation and approval of a new ILC baseline that has been more optimised for cost, performance and risk. We are now completing the design details and embarking on producing the ILC Technical Design Report by the end of this year.

As part of the process of developing the ILC technical design, the GDE project managers have initiated a set of technical baseline reviews of major subsystems. The first of those reviews on the ILC damping rings was carried out in July in Frascati, Italy.

The new ILC baseline shows the way to designing a linear collider that maintains original performance while using cost-saving alternatives.

The last of four proposed major changes to the ILC baseline is to move the positron source to the end of the linac. That proposal has been adopted after evaluating the advantages and the possible options to retain low-energy performance.

Establishing a new baseline for the ILC technical design requires balancing performance, cost and risk issues. A proposal to halve the number of bunches in the machine, reducing power and cost has been approved, following a one-year study of all the impacts.

A freshly released report from the ILC-CLIC working group on general issues summarises general issues and synergies involving a future a linear collider. It also discusses plans for the ILC and CLIC efforts to identify common issues regarding siting, technical issues and project planning.

The SLAC BAW was the second and last such workshop of the so-called Top Level Change Control (TLCC) process, which has been going on for the last twelve months. The SLAC BAW focused on the two remaining TLCC themes: a reduced beam-power parameter set and the location and layout of the positron source.

Today, 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."

Today, 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.
