HELOKA data acquisition and control system: Current development status

HELOKA experimental facility, aimed to test the test blanket modules (TBM) mock-ups and prototypes, is under construction at the Research Centre Karlsruhe. HELOKA is an “8-shape” helium loop (HL), which feeds the TBM test section with helium (1.4 kg/s, 300 °C, 8 MPa). The maximum temperature at the test section outlet is 500 °C. HELOKA data acquisition and control system (DACS) comprises the facility control system and instrumentation. In addition to DACS and working independently from it, the central interlock and safety system (CISS) ensures the facility machine protection and personnel safety, with specific interlock logic, acting upon off-normal events or conditions. The paper briefly describes HELOKA DACS and CISS and reports in detail on the current development status: the installation and commissioning of DACS stage 1 consisting of the supervisory control system (SCS) and the control and monitoring for the water cooling system (WCS) and the related power supply.
