                                    Next steps toward the Strategic Plan



Suggested questions for the discussion sessions:

�What are the most important physics questions that youplan to study at ATLAS over the next five years?

�How do these questions relate to the ATLAS Strategic Plan & the ATLAS efficiency and intensity upgrade plans? For further information see: http://​www​.phy​.anl​.gov/​a​t​l​a​s​/​w​o​r​k​s​h​o​p​09​/​i​n​d​e​x​.html

�How do these questions relate to the national priorities as expressed in 

(1)   the 2007 NSAC  Long Range Plan 


(2)   the DOE-OMB performance measures?

�What other developments in accelerator capabilities and instrumentation do you envision as being needed to optimize your research program at the facility? Consider options included in the current plans and new possibilities.

�Did you identify other important issues that the Executive Committee of the ATLAS User Group and the ATLAS management should make a priority for the facility?
