Madison, May 20, 2009 Tom Gaisser7 Support for physics analysis The Committee was glad to see that real physics analysis is now starting using the IceCube data but would like to understand in the future how the analysis will be organized and how sufficient manpower will be gathered to cover all of the physics opportunities. MREFC ramp-down removes central support for young scientists. It is imperative that funding be secured for the next several years to allow this group to participate in the physics program of IceCube. If funding for 15 of these individuals can be obtained, the US effort can be brought to a healthy number, 28 scientists and 27 students plus faculty. –We recommend that the IceCube collaboration consider submitting a new coordinated supplemental grant proposal to empower the universities to play a leading role in IceCube physics program

Madison, May 20, 2009 Tom Gaisser8 Status of base grants & MOUs Annual NSF review was May 6, 7 –See executive summary report on docushare U.S. base grants being negotiated now Program officers using MOUs as guide to needed funding levels –Current round of proposals from U.S. groups Base grants receiving significant increases Somewhat less than requested M&O proposal assumes increased level in base grants –New institutions are getting support MOUs available by link / handout

Madison, May 20, 2009 Tom Gaisser12 M&O support It is now imperative to provide the M&O funding so that the physics potential of the experiment can be exploited. Since this is an international experiment, other countries should also be providing their fair share of M&O support. –The Committee requests that the M&O funding plan be fully described at the next meeting and that the IceCube collaboration work with the NSF and other country agencies to assure that the M&O tasks are fully covered in a fair and adequate division.

Madison, May 20, 2009 Tom Gaisser13 Status of M&O Proposal submitted April 7 –Request support for 5 years starting 2010 –Review panel May 7 / 8 –MOU coordinated with M&O task list Emphasis on distribution of effort across the collaboration –Status report in Jim Yeck’s talk next on agenda

Madison, May 20, 2009 Tom Gaisser14 Analysis plans Recommendation 1.We recommend that each analysis topic establishes its own set of necessary tasks to be completed and clear milestone dates for their execution. 2.We would further suggest that by the time of our next meeting the Committee is presented with much more information on the plans for assessing systematic uncertainties for each of the main upcoming topics for the next 1- 2 years…. 3.Experimental cross checks, validation, and error assessment often require most of the effort. Responses – see Elisa Resconi’s presentation as analysis coordinator 1.Working group wiki’s 2.Systematic uncertainties a main focus of analysis phone calls & wiki and of calibration phone calls & wiki 3.L2a story as an example

Madison, May 20, 2009 Tom Gaisser25 Use of S.A.C. The Committee hopes that the comments of the SAC group are helpful for the IceCube program and encourages the collaboration to think about how the SAC can best be used in the future. We would like to arrange meetings so that more of the collaboration scientists are involved. –Two possibilities: Set SAC meeting to overlap with end of collaboration meeting SAC members attend some of collaboration meeting Some of both
