2023-B General User Proposal Call (HFIR Submissions only)

The Neutron Sciences General User Proposal Call 2023-B closed on February 22, 2023. Instrument requests are limited to HFIR only for both 2023-B and 2024-A.

Proposals awarded 2023-B beam time at HFIR are anticipated to run from September 2023 to January 2024. 

Due to the planned Proton Power Upgrade (PPU) outage starting in August 2023, SNS instruments will not be accepting proposals in the 2023-B or 2024-A proposal calls. The current HFIR/SNS 5-Year Working Schedule expects SNS availability to resume July 2024 contingent on PPU progress. Details about SNS availability in future proposal calls will be posted here.

Award notices for 2023-B were sent April 26, 2023. Submission dates for 2024-A follow below.
