4. Demand for access to synchrotrons to carry out x-ray crystallographic studies of biological macromolecules is increasing rapidly.

6. Although biologists are increasingly heavy users, operational support comes largely from physics and material sciences at DOE and NSF.

8. Improve staffing levels at existing beamlines.

9. Upgrade detectors and other equipment.

10. Continue efforts to support R&D.

11. Improved access procedures.

12. Upgrade of facility operations.

13. Expansions of existing crystallographic capabilities.
