5. Charge to Participants
The purpose of the Preliminary Design Review for the Green Bank Spectrometer is to validate that the designs and plans presented, to the extent they can be evaluated at this point in the project, meet the guidelines for the new spectrometer by:
1. Satisfying the science case
2. Addressing all of the specifications
3. Meeting the requirements of the ATI grant description
4. Appearing to be technically and financially viable
5. Being able to be completed in accordance with the grant and project schedules
6. Identifying the risks of the project, their potential effect, and demonstrating a satisfactory mitigation plan for each risk

6. ATI Grant Award Details
Science case – Upcoming in next presentations
Schedule
36 months
September 1, 2010 – August 31, 2013
Total Budget - $ 1.27MM ($1.1MM Grant + $170K NRAO Cost Share)
Hardware
Staffing – Who does what?
Science case and system specifications – NRAO & Berkeley
System design and programming – Berkeley
Integration into GB systems – NRAO

7. 05/08/09
Equipment Budget: $435,441
we don't need that many roaches and iadcs (those numbers are from the original proposal). we need about 10 roach boards and 20 adcs.
