LCLS is home to nine beamlines with drastically differing capabilities and competencies. These beamlines are comprised of a wide variety of different devices, and are frequently reconfigured to improve these capabilities or fit the current experiment. This varied and rapidly changing environment has made automating system configuration checks a challenging but vital step toward consistently performing high impact research. LCLS has begun development on ATEF (automated test execution framework), which aims to provide a framework for LCLS scientists to perform system configuration checks quickly and reproducibly. Atef offers a suite of tools for performing both active and passive checks built on the Bluesky/Ophyd data collection framework, as well as a Qt-based GUI for constructing and configuring said checks. This talk will outline the development of this tool, along with lessons learned through its initial deployment amongst our beamlines.

The Linac Coherent Light Source (LCLS) has been undergoing upgrades for several years now through at least two separate major projects: LCLS-II a DOE 403.13b project responsible for upgrading the accelerator, undulators and some front-end beam delivery systems, and the LCLS-II Strategic Initiative or L2SI project which assumed responsibility for upgrading the experiment endstations to fully utilize the new XFEL machine capabilities to be delivered by LCLS-II. Both projects included scope to design, install and commission a control system prepared to handle the risks associated with the tenfold increase in beam power we will eventually achieve. This paper provides an overview of the new control system architecture from the LCLS-II and L2SI projects and status of its commissioning.
