Summary and Conclusions
In Process of Building Injector OrganizationInjector Configuration FinalizedSector 20 Alcove Will be New Construction
~850 sq. ft. for Drive Laser Bay and Optical Lab/StorageMore Space for Cathode Lab
Injector Schedule:Installation Plan Tied to Linac Downtimes~400 days for injector commissioningWorking to Shorten Drive Laser Schedule
Design and Procurement Plan:Improves and Re-Uses Existing SLAC Designs Utilizes Competent Vendors
