Lead–gold eutectic: An alternative liquid target material candidate for high power spallation neutron sources

A comparative study on the compatibility of liquid lead–gold eutectic and liquid lead–bismuth eutectic with T91 and SS 316LN steels

“…LGE is chemically less toxic as compared with mercury (Hg) and produces less polonium as compared with lead-bismuth eutectic (LBE) but has neutron production similar to that of Hg or LBE [1][2][3]. With a melting point of 212°C, it should not be difficult to keep the operating temperature of the target at relatively low temperatures (e.g.…”

Neutron microtomography of voids in gold

“…Regarding the future scientific/industrial applications for the Neutron Microscope instrument, the author trusts that neutron microtomography might be of interest to the material science of precious metal alloys (e.g. [15] , [16] , etc.).…”

PSI ‘Neutron Microscope’ at ILL-D50 Beamline - First Results

“…The detailed description of the results of these neutron microtomographies goes beyond the purpose and the scope of this paper. However, Figure 3 provides an example of the high quality of the resulting datasets showing a randomly chosen vertical slice from the microtomographic dataset revealing in detail the dendritic microstructure of lead in a gold-lead alloy [20] with unprecedented spatial resolution. From the point of view of the temporal resolution, the presented lead-gold alloy microtomography required approximately 12 hours of beamtime onlyincluding the acquisition of open beam, dark current and black body [21] images.…”
