Extended-Capacity High-Speed-Disk Recording System for TREAT Hodoscope

摘要

New requirements for time resolution, test duration, field of view, and recording redundancy in dynamic digital radiographic imaging of fuel motion in TREAT and TREAT-Upgrade (TU) in-pile experiments have been formulated. This has necessitated the design and fabrication of a new hodoscope high-speed data acquisition system. Recently an array of proportional counters was installed to operate in tandem with the Hornyak-button array. The full implementation of this new array, together with the increased field-of-view needed for future TU 37-pin experiments, required a separate recording system operting in parallel with that for the Hornyak buttons. The new recording system was required to have substantially higher capacity than the earlier recording system in use, in order to record sufficient data channels and samples with adequately small collection intervals, for some new types of experiments.
