Abstract:
1. An apparatus for efficiently detecting neutrons, the apparatus comprising: a particle-detecting first substrate having top and back surfaces and including an array of sinuous fins spaced apart by a corresponding array of sinuous channels at the top surface, each of the channels having a depth, a width and a length greater than the width wherein each of the channels is sinuous along the length of the channel at the top surface and wherein each of the fins has a fin width and a fin length greater than the fin width and wherein each of the fins is sinuous along the fin length of the fin at the top surface; and neutron-responsive material disposed in the array of sinuous channels, the material being responsive to neutrons absorbed thereby for releasing ionizing radiation reaction products wherein the sinuous shape of the fins and channels strengthens the fins and reduces neutron streaming effects whereby the apparatus has a relatively flat and uniform detection efficiency response.
