Abstract

The neutron-induced low temperature (below 5 K) luminescence of neutron shielding and scintillation detection materials is studied. Strong luminescence is observed for the neutron absorbing materials boron nitride (BN) and lithium fluoride (LiF). A measurable, but substantially smaller luminescence is observed from boron oxide (B₂O₃). An upper bound of 10 ^-3 was determined for the fraction of the luminescence due to time-correlated multiphoton events in the BN. Other materials tested - boron carbide (B₄C), polymethyl methacrylate (PMMA or acrylic), expanded polytetrafluoroethylene (PTFE) with an evaporated coating of the downconverting fluor tetraphenyl butadiene (TPB) and a boron/lithium loaded glass - displayed no detectable luminescence. The boron/lithium loaded glass was determined to activate, by the secondary reaction ¹⁶O(T,n)¹⁸F, with the triton produced in the neutron capture reaction ⁶Li(n,T) ⁴He.
