Data Acquisition and Control System for Samsung Superconductor Test Facility

Samsung Superconductor Test Facility (SSTF), a superconductor and superconducting magnet test facility, has been constructed at Samsung Advanced Institute of Technology. The main purpose of SSTF is to manufacture and test superconducting magnets for the Korean Superconducting Tokamak Advanced Research tokamak. The data Acquisition and Control (DAC) system for SSTF is composed of UNIX workstations, VME controllers running VxWorks real time OS, VME I/O modules and PLC. The quench detection and magnet protection system using Digital Signal Processors are being developed. EPICS is used for the acquisition and distribution of experimental data via TCP/IP. A script-based interpretive shell program and commercial Mathematica are used to manipulate the experimental raw data produced by EPICS in the Channel Access (CA) server. We present here the status of the SSTF DAC system and the recent results of commissioning and superconductor sample test.
