DISCLAIMER: There is no solicitation at this time. This Sources Sought is not a Request for Proposals. Submission of any information in response to this request is purely voluntary. SLAC will not pay for any costs incurred nor is obligated to respond. All submissions become SLAC property and will not be returned.BACKGROUND: SLAC is operated by Stanford University as a contractor for the United States Department of Energy (DOE) Office of Science (SC). SLAC seeks to increase the maximum X-ray energy capability of an existing hard X-Ray Free Electron Laser (XFEL) facility through the implementation of its LINAC Coherent Light Source II High Energy (LCLS-II-HE) Project. A Low Emittance Injector Tunnel (LEIT) will be part of the supporting infrastructure for the LCLS-II-HE Upgrade. The LEIT will house a lower emittance electron beam source (injector), which is required to achieve the upgrade. Correspondingly, the LEIT Project comprises the design and construction of the tunnel and supporting infrastructure for the injector. The LEIT will be located on the west side of the (SLAC) Campus in Menlo Park, California.SUBMISSION INSTRUCTIONS:Submission Instructions: Interested parties are invited to submit a response to the above questions to jamesy@slac.stanford.edu with "LEIT PROJECT Sources Sought Response" inserted in the subject line of the email.
