Requesting Beam Time

To request beam time at the NSLS, use one of the following options depending on your research:

• General User Proposal Program
• Proprietary Research Program

If you are a member of a Contributing User program (definition) or Participating Research Team (definition), please contact your beamline spokesperson.

There are also specialized purposes under which you may request beam time, both of which require meeting with the NSLS Chairman. These include:

• Discretionary Time (e.g., feasibility studies)
• Classified Research
