A RELATIONAL DATABASE FOR MAGNETS AND MEASUREMENT SYSTEMS AT THE FERMILAB MAGNET TEST FACILITY

摘要

A magnet measurement system based on relational database technology has been developed for use at the Fermilab Magnet Test Facility (MTF). Results of magnetic field strength and field shape measurements are stored in the database for use in understanding accelerator and beamline operation. In addition to measurement results, the database is used to store measurement history and the commands which prescribe measurement sequences along with supporting parameters that control how each measurement is performed. The system contains more than 200 tables with more than 1500 columns. The design of the tables is documented in the form of diagrams, design documents, as well as through tables which store, within the database itself, descriptions of each table and column.
