Director's Review of ERL@CESR

Aug. 2-3, 2007
701 Clark Hall

Charge to the External Reviewers

The Agenda will not include all important subjects but the introductory presentation will attempt to define those subjects that are not treated as well as to list known R&D items associated with them.

The presentations will discuss considerations that have been made and define remaining work, including R&D items.

Please write me an informal letter by email after the review summarizing your thoughts

Please comment on or recommend

• important subjects not mentioned or defined properly
• completeness of considerations presented, further work needed, R&D needed but not mentioned
• economies in design that may be effected without compromising technical capabilities
• note R&D elsewhere that is synergistic with ERL@CESR and which might benefit our effort.
• any other thing that you believe would be helpful to success

Charge to the Cornell Presenters

• Discuss work done to date regarding the agenda item(s) that you are giving, defining items not yet tackled and R&D items that need to be done to achieve technical readiness for construction
• Define related subjects not yet explored but needing exploration before a design can be called complete together with an idea about how the work might be accomplished
