Neutron detection apparatus and method

1. Apparatus for neutron detection, comprising a sensor medium juxtaposed to and in electrical contact with an electrode arrangement conformed to collect radiation-generated charge directly from the sensor medium, wherein the sensor medium consists essentially of a borazine-based polymer, wherein the borazine-based polymer comprises substituted borazine monomers.

2. The apparatus of claim 1 , wherein the sensor medium consists essentially of a borazine-based polymer film enclosed between a pair of electrodes.

3. The apparatus of claim 1 , wherein the sensor medium fills a cavity in a substrate.

4. The apparatus of claim 3 , wherein the substrate is a silicon or SOI wafer or portion thereof.

5. The apparatus of claim 1 , wherein the electrode arrangement is patterned so as to define an array of individual pixels.

6. The apparatus of claim 5 , wherein each pixel has a respective sensor medium that is discontinuous from the sensor media of the other pixels.

7. The apparatus of claim 5 , wherein a plurality of pixels share a common, continuous sensor medium.

8. The apparatus of claim 1 , further comprising one or more photosensors arranged to collect light generated by scintillation events within the sensor medium.

9. The apparatus of claim 1 , wherein said sensor medium is one of a plurality of sensor media arranged in a multilayered stack, each sensor medium is in electrical contact with a respective electrode arrangement, and the apparatus further comprises electrical circuitry conformed to infer neutron energies, at least in part, from penetration depths of neutrons into the stack.

10. The apparatus of claim 1 , wherein the sensor medium consists essentially of a film of poly(borazinyl amine) enclosed between a pair of electrodes.
