Document Summary
Most proposals requesting beam time at nsls-ii are gu proposals. General user (gu) proposals are for scientists that require beam time on beamlines that routinely support the technique needed for their experiment. For gu experiments, users often bring only samples, but can also provide custom instrumentation for the duration of their experiments. General user proposals are valid for one year (3 beam time cycles). Up to three beamlines may be requested for a general user proposal. Each proposal requests a lifetime number of 8-hour shifts to complete the work for each beamline requested. For each cycle that a user requests beam time, he/she must submit a beam time request (btr) against their gu proposal. These proposals are peer-reviewed and allocated by the nsls-ii. All gu proposals are considered active until either: (a) all beam time allocated to the proposal for its lifetime has been used, (b) the proposal is withdrawn, or (c) one year has elapsed.
