A beam physics model server has been developed for the Jefferson Lab accelerator. This online model server is a redesign of the ARTEMIS model server [1]. The need arose from an impedance mismatch between the current requirements and ARTEMIS capabilities. The purpose of the model server is to grant access to both static (machine lattice parameters) and dynamic (actual machine settings) data using a single programming interface. A set of useful optics calculations (R-Matrix, orbit fit, etc.) has also been implemented and can be invoked by clients via the model interface. Clients may also register their own dynamic models in the server. The server interacts with clients using the CDEV protocol, and data integrity is guaranteed by a relational database (ORACLE) accessed through a persistence layer. By providing a centralized repository for both data and optics calculations,the following benefits were achieved: optimal use of network consumption, software reuse,and ease of maintenance. This work was supported by the U.S. DOE contract No. DE-AC05-84ER40150. Reference: The Use of ARTEMIS with High-Level Applications, ICALEPCS 95, Chicago, IL, Oct 29-Nov 3, 1995.
