Abstract

The implementation of an ATCA/AXIe board, developed for fast control and data acquisition systems of nuclear fusion devices, is presented. The implemented board was designed for systems requiring high levels of reliability and availability, such as those of long duration discharges or steady-state operation nuclear fusion experiments. Following ITER instrumentation guidelines for rear signals interfaces, the board comprises a passive rear transition module allowing analogue IO cabling connectivity and cable-less hop-swap maintenance of the front board. Onboard ADC modules have differential input, galvanic isolation and an ADC chopper circuit which assures offset compensation over time for integrators used on magnetic diagnostics. Classical clock and trigger synchronism as well as IEEE-1588/IRIG timing are supported. Full ATCA redundancy and management are also provided.
