Get Started as an NSLS-II User

The NSLS-II User Guide is a step-by-step manual to help you apply for beam time, and—once accepted—how to get ready for your experiment, what to do when you get here, and how to report when you leave.


Determine proposal type

All beam time at NSLS-II is allocated based on a peer-reviewed proposal process. To start, you need to identify the type of proposal that fits your needs. You'll need to know either the technique required, the beamline name/number, or the name of the beamline primary contact to use the Beamlines Available for Proposals page (below) to determine the appropriate proposal type.

Beamlines Available for Proposals

If you need additional details on proposal types, review the Guide to Proposal Types or contact the User Administration Office.


Download your proposal template

Based on the proposal type that you'll be making, download the appropriate proposal template below and fill it out. (All templates are in Microsoft Word format.)


Obtain login credentials

Authentication to the Proposal Allocation, Safety, and Scheduling System (PASS) system requires either a BNL domain account or a Google account. If you don't have one of these accounts, sign up for a free Google account before continuing. 


Login to PASS

Once you log in with your authenticated account, you will be able to view a list of your proposals and submit new proposals using the information from your proposal template. Login to PASS.


Note: For those beamline programs that will not be available for several years, NSLS-II has coordinated with other DOE facilities to make specific near-term arrangements to support former NSLS users. See details of transition programs.

Proposal Review Calendar

Full details of the proposal review process are available in the NSLS-II User Access Policy.
