The response matrix of a neutron spectroscopy system is studied. The system is comprised of successive rectangular parallel layers of BF3 followed sequentially by water layers. In total, ten BF3 (96% 10B) layers and nine H2O ones are configured in periodic order. Two different geometries are investigated; system A and system B. MCNP-4C is used to estimate the response functions of both systems. The response matrix of system A shows higher magnitude than those obtained from system B. In addition, the response matrix of system A shows more distinctive behavior than that obtained from system B.
