Getting approved and scheduled for beam time

See the NSLS II User Guide for up-to-date procedures on preparing a proposal, required trainings, and deadlines. The operating schedule is split into three cycles per year. Beam time is allocated on a competitive basis through the NSLS-II proposal system.

To apply:

1. Register as a user in PASS.
2. Submit a proposal for beam time. It is highly recommended that you contact the beamline scientist to discuss feasibility of proposed experiments and share a proposal draft well in advance of submitting your proposal. After submitting a proposal, please send an updated copy of the proposal to the beamline scientist with changes tracked from the last draft version that the beamline scientist saw.
3. If you already have an active proposal, submit a beam time request. Remember you must request beam time EVERY CYCLE.
4. The proposals will be reviewed. The beamline scientist will notify you whether or not your proposal was allocated time. At this point, let the beamline scientist know your unavailable dates at a minimum, and feel free to also provide preferred and non-preferred dates.
5. If beam time is allocated and a suitable time is found, the beamline scientist will notify you of your scheduled beam time dates.
