Tunneling workshop (July 9-10)

  Monday July 9, AM    Joint with M3 (Linear Colliders) ,  Cabaret room, Silvertree hotel, ground floor
Goal: Presentations by proponents of the four accelerators and a brief overview of the geologic settings of the California, Illinois and other sites. The objective here will be to give the participants an understanding of the main factors that have driven project layouts and, in particular, review the studies conducted to date.

  Monday July 9, PM,  Oxbow room  (Snowmass mall)
Goal: Discussions of the main concerns of the accelerator physicists relative to the installation, operation and maintenance of the underground facilities. The main objective here will be to present the tunnel experts with a list of key design requirements for each accelerator site. A tentative set of discussion items will be developed based on Expert and Working Group input.
Discussion  13:45-17:30

  Tuesday July 10, AM,  Albert room (Silvertree hotel)
Goal: Discussions on potential ways for improving the facility layouts and designs (improving stability, watertightness, constructability, etc..), and reducing design risk and lowering costs. The main objective here will be to interact with the experts with a prioritized list of key design elements that have been assumed for each accelerator site. A tentative set of discussion items will be developed based on Expert and Working Group input.
Discussion 8:30-12:30

  Tuesday July 10, PM,  Oxbow room
Goal: Recommendations for future work, including a listing of areas where more data (accelerator and site) is needed, a listing of proposed improvements to the underground layouts and designs and a shortlist of the more promising R&D ideas that might have been identified during the workshop. For each R&D idea a rough scope of work should be developed and an order of magnitude estimate of "risk versus reward" identified and a ROADMAP developed.
