Ultra-thin 3D silicon sensors for neutron detection
We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 μm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the neutrons in a mixed neutron-gamma ray environm...

| Sumario: | We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 μm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the neutrons in a mixed neutron-gamma ray environment. The device upper-side is covered with a novel boron-based compound that detects neutrons by means of the 10B(n,α)7Li nuclear reaction. The performance of test devices has been investigated first with a gamma-ray source to evaluate the gamma-ray rejection factor, and then with an 241AmBe neutron source to assess the neutron-gamma ray discrimination properties. © 2012 IOP Publishing Ltd and Sissa Medialab srl. |
