Abstract
The efficiency and energy resolution of the MAST neutron camera detectors, based on liquid scintillator of the EJ-301 type, is lower than cylindrical detector of similar size. An experimental investigation has identified light attenuation as the main cause of this deterioration. This finding is supported by Monte Carlo electron and photon transport calculations.
