Neutron-induced luminescence and activation in neutron shielding and scintillation detection materials at cryogenic temperatures
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004Co-Authors: S. N. Dzhosyuk, C. E. H. Mattoni, Daniel Mckinsey, Alan K. Thompson, Liang Yang, John M. Doyle, P.r. HuffmanAbstract: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.

process for Coating an article with an anti fouling surface Coating by vacuum evaporation
2005Co-Authors: Gerald FournandAbstract:The invention relates to a process for depositing an anti-fouling top coat onto the outermost Coating layer of a coated optical article, comprising the following steps: a) providing an optical article having two main faces, at least one of which being coated with an outermost layer; b) treating said outermost layer with energetic species resulting in surface physical attack and/or chemical modification; and c) vacuum evaporating a liquid Coating material for an anti-fouling top coat by means of an evaporation device, resulting in the deposition of the Evaporated Coating material onto the treated outermost layer of the optical article, wherein prior to the vacuum evaporation step of the liquid Coating material, said liquid Coating material has been treated with energetic species.
