SPEAR 3 Upgrade Project: The Final Year

Technical Report ·
DOI:https://doi.org/10.2172/826842· OSTI ID:826842
During April, 2003, the SPEAR 2 storage ring, which served the high energy physics community from 1972 to 1987, and the synchrotron radiation community for an additional 15 years, was removed from its shielding tunnel in order to install the new 3-GeV, 500-mA SPEAR 3 light source. From May to November, SSRL will excavate the tunnel floor and pour a new concrete floor, and then install pre-assembled girders holding magnets, copper vacuum chambers, PEP-II-style rf cavities, and beam line front end components. At the same time, power supply, instrumentation and control, and other ancillary systems will be configured, leading to a commissioning period beginning in November 2003. The progress of accelerator component implementation and installation during the final year of the project will be reviewed.
