As a result of the enactment of the American Recovery and Reinvestment Act of 2009, NSF is holding a competition that is separate from the regular MRI competition. For this MRI-R2 competition only, proposals will be accepted for instrument development or for acquisition of a single instrument or a system of related instruments that share a common or specific research focus in the range $100,000-$6 million from Ph.D.-granting institutions of higher education and non-degree-granting organizations; up to $6 million (there is no minimum request) from non-Ph.D.-granting institutions of higher education or the disciplines of mathematical sciences or social, behavioral, and economic sciences at any eligible organization.
