Sector-20 Injector Home Page

The last kilometer of the SLAC 3-km linac will be used to provide a 10-15 GeV beam for the LCLS. A new off-axis injector will be built at Sector 20 in an existing vault. The injector utilizes an S-band rf gun with a metal photocathode. The laser for exciting the cathode will be in a laser room which will be inside an existing building above the vault. A brief description of the injector is found in a presentation made at FEL2001. For a more complete description, see chapter 6 of the LCLS Conceptual Design Report.

The LCLS Project preliminary schedule shows construction beginning in FY06. However, the plan is to build the injector in FY05 as a long-lead procurement project. Thus the Project Engineering Design (PED) for the injector will take place principally in FY03 and FY04. The PED includes some prototyping.

The funding schedule for the LCLS will provide only very modest funds for the injector PED in FY03. The plan is to provide the bulk of the injector PED funding in FY04. Some PED work will continue in FY05 during construction.

NEW (11/13/02): Newport Corporation has signed a contract with IBM to produce aspheric lenses. Work on the first lens might begin as early as January 2003. SLAC is negotiating to test the first lens produced.
