Title: Advanced light source at Lawrence Berkeley Laboratory

Abstract

The 1--2-GeV synchrotron radiation source will be a national user-based facility providing photon beams of unprecedented brightness in the ultraviolet and soft x-ray region of the electromagnetic spectrum. The facility design is optimized to emphasize the use of undulators to provide high-spectral brilliance in the few electron volt to 1-keV spectral range; wigglers provide high flux up to approximately 10 keV. Beam structure of a few tens of picoseconds will be available for time-resolved experiments. The facility is designed for operational flexibility and to assure rapid commissioning. The initial complement of experimental stations consists of five insertion devices (four undulators and our wiggler) and associated beamlines, and two white light beams from bend magnets. Six other straight sections are available for additional insertion devices, and the design provides for up to 48 ports for beams from bending magnets. The storage ring is optimized for operation at 1.5 GeV with a maximum energy of 1.9 GeV. The injection system includes a 1-Hz, 1.5-GeV booster synchrotron for full energy injection at the nominal operating energy of the storage ring. Filling time for the maximum stored current of 400 mA is expected to be 2 min, and the beam half-life will be aboutmore » 6 h. Attention is being given to the severe requirements for beam stability and the need to independently control photon beam alignment. We describe the important characteristics of the facility, significant aspects of the technical design of accelerator systems, insertion devices and photon beamlines, and considerations related to addressing projected user needs in the development of the project.« less
