Data Acquisition and Database Management System for Samsung Superconductor Test Facility

Title: Data Acquisition and Database Management System for Samsung Superconductor Test Facility

Research Question: How was a data acquisition and database management system implemented for the Samsung Superconductor Test Facility (SSTF)?

Methodology: The researchers designed a data acquisition and control (DAC) system based on UNIX and Linux systems, using VxWorks and RTEMS for real-time OS of VME systems. EPICS was used for communication between IOC server and client. A database program was developed for efficient management of measured data, using a Linux workstation with PENTIUM-4 CPU as the database server.

Results: The SSTF DAC system successfully acquired and managed data from various sources, including slow-varying parameters, high-speed data acquisition systems, and independent devices. The system was able to handle 64 channels with 100 kHz sampling rate. The data was stored in an in-house developed database using NFS, allowing for monitoring using an in-house developed quasi-real-time monitoring system.

Implications: The implementation of this data acquisition and database management system enabled efficient data management and monitoring for the Samsung Superconductor Test Facility, ensuring accurate and timely data acquisition for the testing of superconducting strands, conductors, and magnets. This research contributes to the field of data acquisition and control systems, particularly in the context of superconducting magnet systems.
