  The Controls Department at SLAC, with its service center model, continuously receives engineering requests to design, build and support controls for accelerator systems lab-wide. Each customer request can vary in complexity from installing a minor feature to enhancing a major subsystem. Departmental accelerator improvement projects, along with DOE-approved construction projects, also contribute heavily to the work load. These various customer requests and projects, paired with the ongoing operational maintenance and problem reports, place a demand on the department that usually exceeds the capacity of available resources. An integrated, centralized repository - comprised of all problems, requests, and project tasks - available to all customers, operators, managers, and engineers alike - is essential to capture, communicate, prioritize, assign, schedule, track progress, and finally, commission all work components. The Controls software group has recently integrated its request/task management into its online problem tracking "Comprehensive Accelerator Tool for Enhancing Reliability" (CATER ) tool. This paper discusses the new integrated software problem/request/task management tool - its work-flow, reporting capability, and its many benefits.

  The successful commissioning and initial series of experiments at SLAC's Linac Coherent Light Source (LCLS) have been the culmination of a significant effort to integrate new, state-of-the-art controls with legacy controls of the SLAC linac. The controls architecture consists of a distributed system of EPICS IOCs and Linux servers operating in conjunction with an older system consisting of centralized VMS facility, CAMAC fieldbus and Intel industrial front-end processors. A rich and burgeoning suite of high level Java and MATLAB applications provide data acquisition and analysis tools for diagnosing, tuning and optimizing the machine. A relational database unites the configuration control, online modeling and reference beam data. The AIDA middleware provides transparent access to data from either controls systems and has allowed engineers to migrate to new platforms without requiring changes to applications software. A recent upgrade of the legacy Linac controls includes a data bridge from the CAMAC system to VME IOCs which results in uniform EPICS channel access interface to entire LCLS controls data. One of the many design challenges has been to provide such data synchronously with the timing system on a pulse-by-pulse basis at 120 Hz to support beam-based feedback and other applications.
