The National Science Foundation (NSF) invites proposals for the Major Research Instrumentation Program (MRI). See Program Solicitation NSF 07-510 at: http://www.nsf.gov/pubs/2007/nsf07510/nsf07510.htm This solicitation addresses major instrument acquisition or instrument development that is too costly for support through other NSF programs.
NSF limits institutions to three submissions, two for instrument acquisition and one for instrument development.
