The Dear Colleague Letter: NSF Options to Address Helium Supply Short Concerns (NSF 22-088) has been archived and replaced by Track 3 in the Major Research Instrumentation (MRI) solicitation  (23-519).  In 2023, MRI will have two submission windows:  January 16-February 21 and October 16-November 15.

The MRI Program serves to increase access to multi-user scientific and engineering instrumentation for research and research training in our Nation’s institutions of higher education and not-for-profit scientific/engineering research organizations.  An MRI proposal may request up to $4 million for either acquisition or development of a research instrument. 

The Tracks for MRI proposals have been revised and now include:

• Track 1: Track 1 MRI proposals are those that request funds from NSF greater than $100,000 and less than $1,400,000.
• Track 2: Track 2 MRI proposals are those that request funds from NSF greater than or equal to $1,400,000 up to and including $4,000,000.
• Track 3: Track 3 MRI proposals are those that request funds from NSF greater than or equal to $100,000 and less than or equal to $4,000,000 that include the purchase, installation, operation, and maintenance of equipment and instrumentation to conserve or reduce the consumption of helium.

Please note that each performing organization may submit up to four MRI proposals:  no more than two submissions in Track 1, no more than one submission in Track 2, and no more than one submission in Track 3.
