Relational Database Design for the Test of the Kstar Superconducting Magnet System

The Korea Superconducting Tokamak Advanced Research (KSTAR) superconducting magnet system consists of 16 TF (Toroidal Field) and 14 PF (Poloidal Field) coils. Both of TF and PF coils use internally-cooled conductors. In order to validate the design of the KSTAR TF coil, a full-scale prototype TF coil, TF00, is developed. For the test of TF00, a large scale superconducting magnet and conductor test facility, SSTF (Samsung Superconductor Test Facility), has been constructed. The data acquisition and control system for SSTF is based on Linux system and Experimental Physics and Industrial Control System (EPICS) is used for the acquisition and distribution of experimental data. A relational database management system is used for the configuration of the EPICS record data. Calculation routines, which convert a measured voltage to a physical value, are added to the EPICS IOC (Input-Output Controller) application, which is ported to an i386 PC with the Real-Time Executive for Multiprocessor Systems (RTEMS).
