Figure 1
Cross section of the proposed detector geometry on the yz plane (dimensions not to scale). The attainable polar angle θ ranges from 0 to 90°, with the lowest possible angle of the tube being 1.4° for the chosen detector dimensions. The lines connecting the sample and the anode wires (crosses) represent possible scattered neutron trajectories. The line from the centre of the tube to the centre of the wire defines the azimuthal angle. |
