Beamlines available for proposals

September – December 2018 Cycle

General User (GU) Proposals are for scientists that require beam time on beamlines that routinely support the technique needed for their experiment. General User proposals are valid for one year (3 beam time cycles).

In these early years of NSLS-II, new beamlines capabilities are continually being implemented. This might include commissioning a new beamline, technique, endstation, hardware, and/or software. An essential part of this process involves engagement of the scientific community in user-assisted commissioning of these capabilities. In the past, a separate proposal type (i.e. Science Commissioning proposal) was required.  However, beginning in September 2017, the request for “science commissioning” beam time will be submitted through the General User proposal.

Listed below are the General User and Science Commissioning capabilities that will be available for the upcoming cycle. If a user wishes his/her proposal to be considered for science commissioning beam time based on a new capability specifically requested below by the beamline staff for this cycle, this should be addressed in the General User proposal. In addition, all users interested in science commissioning are required to consult with the lead beamline scientist prior to submission of the proposal.

For more information, see the Guide to Proposal Types.
