There are two ways to obtain beam
time at the NSLS: either as a general user or as a member of a
Participating Research Team (PRT). All operational beamlines at
the NSLS reserve at least 25% of their available beam time for
general users. The process below describes the procedure for
applying for general user beam time.
General User Program
General Users are scientists interested in using the NSLS for experimental programs. Access to the NSLS is
generally obtained through a peer-reviewed proposal system. Proposals are rated by the Proposal Study Panels
(PSPs) and beam time allocations are made by the NSLS Allocation Committee.

PLEASE NOTE: All new users submitting a General User
