    Abstract

    We report recent progress on development of high-resolution instrumentation and measurement techniques for investigation of various thermal-hydraulic processes, such as dynamic gas-liquid two-phase flow. Included in these activities, two projects are currently under development: a novel high-efficiency, one-dimensional fast-neutron imaging detector intended for fan-beam tomography applications, and a cold-neutron large-area imaging detector prototype. Both instruments are based on neutron-to-charge particle conversion coupled to THick Gaseous Electron Multipliers (THGEM) for position-sensitive charge readout. We review the operational principle and properties of the two detector concepts.
