Conclusion

Progress is being made toward completing beamline and component design for 2006 installation supporting January 2007 commissioning but with some riskAdditional engineering manpower required for SAB Spectrometer, BC1 Downbeam segment, BC1 Chicane diagnostics and BC1 Single Shot Bunch Length MonitorVendor delivery delays could be criticalInjector Vault cable tray and water installation must be expedited
