The architecture also includes a complement of engineering and deployment tools including cable test boxes or hardware simulators, as well as some automatic configuration tools. Vacuum controls at LCLS spans from rough vacuum in complex pumping manifolds, protection of highly-sensitive x-ray optics using fast shutters, maintenance of ultra-high vacuum in experimental sample delivery setups, and beyond. Often, the vacuum standards for LCLS systems exceeds what most vendors are experienced with. The system must maintain high-availability, while also remaining flexible and handling ongoing modifications. This paper will review the comprehensive architecture, the requirements of the LCLS systems, and introduce how to use it for new vacuum system designs. The architecture is meant to influence all phases of a vacuum system lifecycle, and ideally could become a shared project for installations beyond LCLS-II.
