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.

I have officially approved two major changes in the ILC baseline configuration for the next phase of our R&D and design work. [...] Today, I discuss the procedure we have followed to evaluate and decide on these changes.

In a new large accelerator complex which will take years to get approved and constructed, one must maintain some degree of flexibility in its design as many things can change before a construction start.

In recent months the project managers have presented a "strawman" baseline (SB2009) to the broader ILC community at a workshop in Albuquerque and to the International Linear Collider Steering Committee's Project Advisory Committee (ILCSC PAC) at a review in Pohang, Korea last November. We have now received the report of the PAC review and I discuss some highlights of that review here.

(...) We are undergoing a process we refer to as Accelerator Design and Integration, from which we expect to make a number of important changes to the baseline for the ILC.

... One of the most complex and difficult changes under consideration is changing from the RDR's double-tunnel to a single-tunnel configuration. A key problem to solve for a single-tunnel configuration is how to deliver the high-level radiofrequency power to the cryomodules.

... A new, more descriptive name for the process we are undertaking, Accelerator Design and Integration, became official at the first working meeting towards defining a new ILC baseline held at DESY from 28 to 29 May.

ILC R&D on superconducting RF technology is of special importance because it represents our central technology, and it is an area where we are forging the way for future accelerators that will employ this forward-looking technology.
