  A compact liquid organic neutron spectrometer (CLONS) based on a single NE213
liquid scintillator (5 cm diam. x 5 cm) is described. The spectrometer is
designed to measure neutron fluence spectra over the energy range 2-200 MeV and
is suitable for use in neutron fields having any type of time structure.
Neutron fluence spectra are obtained from measurements of two-parameter
distributions (counts versus pulse height and pulse shape) using the Bayesian
unfolding code MAXED. Calibration and test measurements made using a pulsed
neutron beam with a continuous energy spectrum are described and the
application of the spectrometer to radiation dose measurements is discussed.
