Abstract
Water-based Cherenkov counters are considered for remote detection of special nuclear materials with aid of active interrogation. We designed and manufactured a detector capable of gamma ray detection and demonstrated particle energy discrimination ability. Background reduction techniques based on energy threshold and photomultiplier tube multiplicity were implemented in particle detection. Both approaches resulted in a significant suppression of low-level background.
