User Administration Office

NSLS-II welcomes visitors from academia, industry, and other government laboratories and research facilities within the U.S. and abroad. The NSLS-II User Administration Office facilitates User and Guest access to the Facility to perform experiments. We are available to assist and support the NSLS-II user community with the beam time application process, user agreements, logistical arrangements, and more.


Check in at the User Administration Office to receive an NSLS-II access card and TLD. The access card will include encoding for access to the Experimental Floor. Check-in may only be performed during normal business hours.*

Where to Find Us

The User Administration Office is located in NSLS-II Building 743. See it on a map (PDF).
