NSLS-II Beamlines

15 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/ mulitple IDs per straight

(plus possible multiple hutches per beamline)

Noise and Stability

One issue users care a lot about is noise:

• Mechanical• Isolate sources of noise• Pay attention to vibration damping (thick slab)

• Electrical• Clean (conditioned) power• Dirty power• High quality grounds for each

• RFI• Shield NEXRAD• Shield local sources (Storage Ring RF cavities)

Summary

• Facility will ultimately support ~60+ beamlines and >3000 users.

• Conceptual designs have been carried out for a number of beamlines to inform a detailed cost estimate, and a number of others at a pre-conceptual level.

• A small number of beamlines will be built as part of the construction project utilizing a trust fund approach. These will begin commissioning in 2013.

• Remaining beamlines will be built with other funds (MIE and other non-BES funds) and brought online in the following years.
