BNNT (Boron Nitride Nanotubes) is a material with excellent mechanical and thermal properties. Enriched with ¹⁰B, an isotope of Boron with a high thermal neutron capture cross-section, it can be used as a neutron-sensing element by measuring the decay products of the ¹⁰B(n,α)-reaction.
Two prototypes based on a ¹⁰B-enriched BNNT mat coupled to inorganic scintillators (BGO and GaGG, respectively) have been developed. The detector systems are read out by a Photomultiplier tube.
Both systems were tested initially for their capabilities as neutron detectors at the DT neutron source at HZDR, Dresden. Those tests and their results will be discussed in the contribution.
This work is part of the ADMIT consortium and financed with funds of LOEWE
