Patent Images
1. A method of fabrication a neutron detector comprising one or more scintillation detector layers in a modular configuration, the method comprising:
- a. mixing 6LiF with a binder medium with a scintillator material to form a plurality of active scintillation layers;
b. interleaving layers of fiber optics and the plurality of active scintillation layers stacked on top of each other to make at least one multi-layer detector, the fiber optics comprising optical light media having at least one end;
c. separating at least two of the plurality of multi-layer detectors with moderator material;
d. coupling the at least one end of the optical light media to at least one photo sensor; and
e. coupling the at least one photo sensor to a pre-amp which is further coupled to a digital signal processor.

Abstract
A fabrication method is provided for making a high efficiency neutron detector using a scintillator medium coupled with fiber optic light guides. The light guides provide light pulses to photo sensor and thereby to high speed analog to digital conversion and digital electronics that perform digital pulse shape discrimination for near zero gamma cross talk.
