What to Do Before Your Beam Time

Once your proposal has been accepted, get ready for your beam time at NSLS-II.


Register for a user appointment

All facility users performing experiments at NSLS-II are required to have an active appointment with Brookhaven National Laboratory. Requests are submitted through our online Guest Information System. Users who have previously registered and have an active BNL appointment may skip this step. You must register through the Guest Information System at least 30 days prior to your beam time. Provide a clear justification for your visit including the beamline that you are planning to use. The request must also be approved by the relevant beamline Lead Scientist or designated contact. Appointments expire after two years but can be renewed.


Complete required training

Once your guest appointment has been approved, you must complete the online training modules before experiments may begin. The User training modules described in this section must be completed online prior to the start of beam time. Please complete the following training courses. For returning users, you can check your training status online.

* Required only for onsite users (not remote-access users).

Note: If you have completed BNL GERT training in the past, then you may take the GERT Challenge Exam to renew your GERT training. If you have valid GERT training from another DOE light source facility (APS, ALS, SSRL, or LCLS), we accept GERT reciprocity.


Submit Safety Approval Forms

All materials, equipment, and researchers involved in the experiments are listed on the Safety Approval Form (SAF), which includes an explanation and risk analysis for the tasks to be completed during the beam time (at the beamline and within the set-up laboratories). SAFs must be submitted at least 14 days prior to the start of beam time. Failure to submit a SAF at least 14 days in advance can result in cancellation of your beam time and reallocation to another user. All SAFs are valid for one year except Rapid Access, which are valid for one beam time cycle. Risks outside the standard hazard envelope (e.g. work with biohazards, transuranics, pressure systems …) require more processing time. In these cases, users should contact the Experiment Review Coordinator as early as practical during experiment planning.

SAFs are submitted via the Proposal Allocation, Safety, and Scheduling System (PASS) once a proposal is allocated beam time. For more details and guidance on completing your SAF, consult this guidance document.


Prepare for your beam time

Reserve accommodations
If you will be coming to NSLS-II for beam time, there are a number of hotels near BNL and the Laboratory also offers inexpensive onsite housing. See hotels near BNL and onsite housing options.

Ship materials to NSLS-II
Please ship materials to and from NSLS-II in coordination with your home institution or via Federal Express. If this is not possible, or if you have any questions, please contact the beamline scientist responsible for your beam time. Please see the NSLS-II shipping instructions for more details.

Bring required identification
If you will be traveling to NSLS-II, bring the required identification to finalize (or renew) your appointment and receive a BNL photo badge. The photo badge is required for each visit. Expired documents will result in delays in accessing the BNL site and may prevent entry. Foreign nationals are strongly encouraged to bring their valid passport and all visa documents during every visit, which are required to be on file with the GUV Center and current at all times. Users are also encouraged to carry medical insurance and prescription cards. Additional details.
