  We present Monte Carlo (MC) simulation results from a study of a compact
plastic-scintillator detector suitable for imaging fast neutrons in the 1 -- 10
MeV energy range: the miniTimeCube (mTC). Originally designed for antineutrino
detection, the mTC consists of 24 MultiChannel Plate (MCP) photodetectors
surrounding a 13 cm cube of boron-doped plastic scintillator. Our simulation
results show that waveform digitization of 1536 optically sensitive channels
surrounding the scintillator should allow for spatiotemporal determination of
individual neutron-proton scatters in the detector volume to $\thicksim$100
picoseconds and $\thicksim$5 mm. A Bayesian estimation framework is presented
for multiple-scatter reconstruction, and is used to estimate the incoming
direction and energy of simulated individual neutrons. Finally, we show how
populations of reconstructed neutrons can be used to estimate the direction and
energy spectrum of nearby simulated neutron sources.
