Snowmass was a big milestone for the GDE. It was the first time the 49 members of the Global Design Effort met together to begin our work. The first week at Snowmass was primarily organized along the lines of the accelerator working groups that were formed last fall at the 1st ILC Workshop. The main GDE influence was adding six global working groups that met each afternoon to begin focusing on overall design issues such as costing, facilities, operations, machine parameters, machine detector interface, etc). These groups made very good progress on these issues.
After the first week of the workshop, the GDE members and working group leaders met on Saturday, 20 August, to plan the second week. In addition to continuing the work begun in the first week, our goals for the second week were to concentrate on identifying the decisions that will need to be made to develop a complete baseline configuration and to make conclusions or recommendations on them, where possible.
So, what happens next? Our plan is to first assemble all the information from Snowmass, post it on the Web site, and let those in the community provide additional inputs. In mid-September, the GDE directorate (Barish, Dugan, Foster and Takasaki) and the GDE accelerator leadership (Yokoya, Raubenheimer and Walker) will meet to consider all these inputs and to begin the process of putting together a 'Strawman' BCD.
In some cases, we expect that we will need more information, and in other cases, we may want to call on expert advice. In any event, we plan to conduct an iterative and open process while working toward the BCD. In mid-November, we will meet again to put together a 'Strawman' BCD, which will be posted and will provide the starting point for the next GDE meeting to be held at Frascati, Italy from December 7-10, 2006. It is our goal to complete the baseline configuration document and alternate R&D plan at the Frascati meeting.
I want to emphasize that the GDE process of getting to a baseline configuration will be as open as possible. We invite and encourage inputs from the broader ILC community at each step in the process, including participation by interested parties in our meetings. You should be able to keep close tabs on our progress on the ILC Web site, where we will be putting together a special section on the BCD.
