title = "Angular response of perforated silicon diode high efficiency neutron detectors",
abstract = "Perforated silicon diodes with two different etched patterns were tested for neutron counting efficiency and angular response. The etched patterns consisted of circular holes on a square lattice or continuous sinusoidal waves. Normal incident neutron counting efficiencies were determined to be 21% and 35% for circular hole and sinusoidal devices, respectively. A non-uniform angular response was identified for the circular hole perforated devices. For the circular hole patterns, a reduction in efficiency appeared at azimuthal angles near 0° and 90°, each referenced at a 90° polar angle about the normal axis. The non-uniform angular response is due to neutron streaming paths through the square lattice. The sinusoidal device angular response was uniform and matched well to that of a standard simple planar device.",
