DESCRIPTION
3 BROOKHAVEN SCIENCE ASSOCIATES Modes of Access General Users (GUs) Users apply for time on facility or non-facility beamlines. Proposals can be one time (one cycle) or two year (program). Provision also for rapid access on certain beamlines (reviewed after the fact). Contributing Users (CUs) Individuals or groups who carry out research at NSLSII Facility Beamlines and also enhance beamline capabilities and/or contribute to their operation.

BDT Access – User run beamlines At least 25% of the time to GU program. Commissioning comes out of BDT time. Possible BAT ramp up

Beamline Development
• Beamline Access Teams (BATs) Facility receives funding to design, construct, and operate beamlines.
• Beamline Development Teams (BDTs)User group receives funding to design, construct, and operate beamline.
Two principal modes :User groups would form and work with the facility to define the scientific mission and technical requirements for the beamline

NSLS-II Beamlines15 five m straights for user undulators
• Could potentially drive up to 30 beamlines by canting two undulators
4 eight m straights for user undulators• Could potentially drive up to 12 beamlines by canting three undulators
8 eight m straights for user damping wigglers• Could potentially drive up to 24 beamlines by canting three DWs
20 BM ports for UV and soft X-rays10 BM ports for IR
• 5 large aperture for far-IR• 5 regular aperture for mid/near-IR
At least 57 beamlinesMany more w/ maximum IDs per straight
(plus possible multiple hutches per beamline)

A strawman beamline distribution was constructed for one possible scenario for a mature facility:
Note: This process took into account the expected demand, the existing community and the enhanced NSLS-II capabilities. In this scenario a few IDs and a few BMs remain open.

Scientific Staff at NSLS-II
Roles and responsibilities of NSLS-II staff• User support and independent research
• What fraction of time on independent research?• Connection to outside community
• Joint Appointments• Role of Joint Photon Science Institute• NSLS-II Fellows
– Very few (1-2) select individuals allocated resources and significant fraction of a beamline (beamtime through CU mode?). Expected to produce at very high level. Rigorously reviewed and competed for.
