Accelerator development and construction projects often intentionally push the envelope of well-established technical performance and manageable complexity. In addition, the desire for efficient retention and exploitation of accumulated experience across the multi-decade life cycles of major installations calls for a robust yet userfriendly knowledge management system. To meet these needs, we are deploying a new web-based system at Jefferson Lab: Pansophy. This system is a custom integration of several commercial software utilities, DocuShare, ColdFusion, Matlab, Ingres, and common desktop programs. Users of the system range from process managers, shop-floor technicians, and test engineers to after-the-fact data miners and operations staff. The system integrates important quality assurance elements of procedural control, automated data accumulation into a secured central database, prompt and reliable data query and retrieval, and online analysis tools, all accessed by users via their platform-independent web browsers. A system overview, a completed pilot project, and implementation experience to date will be presented.

Jefferson Lab has extensively used a proprietary webbased system (Pansophy) that integrates commercial database, data analysis, document archiving and retrieval, and user interface software, as a coherent knowledge management product during the construction of the cryomodules for the SNS Superconducting Linac, providing elements of process and procedure control, data capture and review, and data mining and analysis. With near real-time and potentially global access to production data, process monitoring and performance analyses could be pursued in a timely manner, providing crucial feedback. The extensibility, portability, and accessibility of Pansophy via universally available software components provide the essential features needed in any information and project management system capable of meeting the needs of future accelerator construction efforts, requiring an unprecedented level of regional and international coordination and collaboration, to which Pansophy is well suited.

Jefferson Lab has developed a web-based system that integrates commercial database, data analysis, document archiving and retrieval, and user interface software into a coherent knowledge management product called Pansophy. Pansophy provides key tools for the successful pursuit of major projects such as accelerator system development and construction by offering elements of process and procedure control, data capture and review, and data mining and analysis. Today, Pansophy is used in Jefferson Lab's SNS superconducting linac construction effort as a means for structuring and implementing the QA program, for process control and tracking, and for cryomodule test data capture and presentation/analysis. Development of Pansophy continues, with improvements to data queries and analysis functions that are the cornerstone of its utility. In this paper the present configuration and operational environment of Pansophy is described, along with future development goals. Additionally, specific examples of its use in an accelerator construction project will be presented.
