Dataset summarising experimental results on the performance of a quartz polarisation rotator at low temperature
No full textThis dataset provides the experimental data on the performance of a 13.11 mm crystalline quartz rotator at low temperature. The rage of temperatures covered in this study is between 77 K and 325 K. We measured the temperature dependence of optical activity by propagating 1030 nm laser light collinearly with the optic axis. The effect on the polarisation state of the beam was assessed using an extinction method, where the beam propagates, in succession, through a polariser, the quartz sample and another polariser (analyser). The data is summarised in an Excel document. The first tab relates to data collected by keeping the transmission axes of the polariser and analyser parallel while the temperature of the quartz sample was varied. The other tabs contain the experimental data collected by varying the orientation of the transmission axis of the analyser while keeping the temperature of the quartz sample constant

The data is in the form of figures and tables.
The figures in the corresponding directory were prepared using bash scripts, python version 2.7, gnuplot version 4.6 and latex to extract and analyse simulated data.
The tables in the corresponding directory were prepared using bash scripts and python version 2.7 to extract and analyse simulated data.
The python scripts can be found in the repository. Note that numpy is a requirement.

The raw data was prepared using the SCARF (scarf.rl.ac.uk), CIRRUS (cirrus.ac.uk), University of Liverpool (https://www.liverpool.ac.uk/csd/advanced-research-computing/facilities/high-performance-computing/) and SCAFELLPIKE (http://community.hartree.stfc.ac.uk/wiki/site/admin/home.html) clusters. There is inexcess of 10Gb of data generated by the solvers Code_Saturne (https://www.code-saturne.org/cms/), DYN3D-MG (https://www.hzdr.de/db/Cms?pOid=11771&pNid=542) and SERPENT (http://montecarlo.vtt.fi/).
Code_Saturne (version 5.0) was used to perform simulations of thermal fluid dynamic and conjugate heat transfer of a molten salt fast reactor. The models studied the formation of frozen salt films on cooled reactor vessel walls.
DYN3D-MG modelled the nodal diffusion neutronic behaviour of the molten salt fast reactor.
SERPENT (version 2.1.29) modelled the neutronic behaviour of the molten salt fast reactor using the Monte Carlo method.
Both Code_Saturne and DYN3D-MG were coupled to one another in 3-D simulations of the reactor. The coupling procedures were implemented with the Multiscale Universal Interface, MUI (https://github.com/MxUI/MUI).

Neutron total scattering from solid Athasbasca asphaltenes and Athabasca asphaltenes dissolved in 1-methylnaphthalene-d10 at 25wt% measured on NIMROD
No full textNeutron total scattering from solid Athasbasca asphaltenes measured on NIMROD. Asphaltenes were precipitated from Athabasca bitumen by the addition of heptane at a ratio of 40:1 by weight. The mixture was homogenized by stirring for 24 h, and the asphaltenes were separated by centrifugation at 3472g for 10 min. Solid asphaltenes were washed for 24 h in a Soxhlet extractor with pure heptane and then dried in vacuum oven at 80 °C for 4 days. Because Athabasca bitumen contains inorganic solids, an additional step was taken to isolate the asphaltenes. The solid asphaltene samples were diluted to a 4.8 wt % solution in toluene and centrifuged at 5000g for 270 min to remove the inorganic solids. The toluene was then removed by forced convection and then subsequent drying in a vacuum oven at 80 °C to obtain the solid asphaltene sample used for experimentation. Solution samples were re-dissolved in the appropriate mass of deuterated 1-methylnaphtalene at elevated temperature using a stirrer/hotplate. The sample was contained in a TiZr cell (1mm path length for solutions, 2mm path length for solids) maintained at 20C or 180C using a circulating oil bath. The measured neutron scattering was reduced to the interference differential scattering cross section, F(Q), using the GudrunN program. This program merges the time-of-flight scattering from all detectors to a single Q scale, normalizes to a 3 mm VNb plate calibration standard, subtracts scattering from the sample container and empty instrument, and applies corrections for beam attenuation, multiple scattering and inelastic scattering (by use of an iterative correction).EP/R013195/1 (EPSRC), CBET-1821762 (NSF
