Reconfigurable Timing Unit for NSTX-U
Authors: S. DeLuca, P. Sichta, G. Tchilinguirian
Abstract:
portion of the CAMAC equipment used for data
acquisition and control will be supplanted with instrumentation
and control (I&C) technologies such as CompactPCI and PXI
Express. The Timing and Synchronization System (T&S) is used
to synchronize data acquisition and control throughout the
experimental complex. A non-CAMAC solution is needed to
support the new and upgraded I&C systems for NSTX-U. An
instrumentation-bus-agnostic, FPGA-based T&S system is under
development. The primary component is the Reconfigurable
Timing Unit (RTU). The RTU has been designed to be fully
compatible with NTSX's original T&S. The RTU is the 3rd
NSTX-designed FPGA-based timing device. Unlike its
predecessors, the RTU will rely on commercial products:
LabVIEW software and sbRIO hardware, both from National
Instruments. Our experience in product development, integration
with the NSTX-U computing and control environment, and
timing performance will be presented.
