The objective of the proposed grant was to further explore our recently developed gadolinium-rich semiconducting materials by quantifying the responses to neutrons of these materials, alone and in simple device configurations. Both modeling and laboratory experiments were to supply the data for evaluating the performance of these materials and devices and results of each were be compared with independently obtained data. The lack of quality data from other laboratories curtailed further efforts. Positive results are that the supercritically-grown cubic gadolinium oxide has shown neutron response which may yet hold potential for radiation detection. In addition, some baseline end-use requirements of radiation detection parameters for field deployment have been published.
