Access to the full 3D Brillouin zone with time resolution, using a new tool for pump-probe ARPES
Data presented in figures of manuscript "Access to the full 3D Brillouin zone with time resolution, using a new tool for pump-probe ARPES," also available as preprint at https://arxiv.org/abs/2309.11535 . Generated during Artemis commissioning beamtime 22325000, April-May 2021, using Fermiologics FeSuMa analyzer for pump-probe ARPES measurements on the Artemis Red Dragon 1-kHz beamline.
Outgassing Measurements for "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
Dataset contains raw text files from outgassing measurements of Wire-Arc Additive Manufactured (WAAM) samples presented in the conference paper "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing" (SPIE Optomechanical Engineering 2023) Files contain the pressure and temperature measurements used to calculate outgassing rates for the WAAM samples. For details of the analysis see the paper and the associated GitHub repository. README contains information on raw file format.
Demonstrations of fast approximate variable-width broadening
We have developed a fast approximate method of applying variable-width broadening to spectral data. This dataset contains demonstration scripts which generate the plots for a related academic manuscript. They also reproduce the parametrisation of polynomial fits to the relationship between the approximation error and the scale factor between broadening kernels used in the method. Some of the scripts use the implementation in the Euphonic library: to reproduce published results use Euphonic v1.3.0 - https://pace-neutrons.github.io/Euphonic/versions/v1.3.0.html - https://github.com/pace-neutrons/Euphonic/releases/tag/v1.3.0 Most of the scripts are written in Python. One Bash shell script is also included which needs to call the euphonic-powder-map program included in the Euphonic package. A Makefile is provided so that all plots can be generated with "make plots" using GNU Make. .yaml datafiles were derived from data in the Kyoto phonon database ("phonondb") under a CC-by license: the Phonopy calculation directories were downloaded and Phonopy was run with =--include-all= and =--nac= options to create .yaml files containing all the information needed by Euphonic.
SORS spectra of COVID-19 Vaccine
Spatially Offset Raman Spectra of 45 genuine covid-19 vaccines, and surrogates for potential and intercepted falsified vaccines . The Raman spectra were collected using a handheld commercial SORS instrument (Resolve, Agilent Technologies, Oxfordshire, UK)
Microfluidics and Nanofluidics journal article - "Numerical investigation of transmission probability characteristics in the first low-density region of a laser wakefield accelerator"
Relevant data supporting the manuscript "Numerical investigation of transmission probability characteristics in the first low‑density region of a laser wakefield accelerator" submitted to the Microfluidics and Nanofluidics journal (accepted for publication in July 2023).
CAD files from "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
Files contain .step files for the topology-optimised design and the varied wall thickness design. These designs are detailed in the paper submitted to SPIE Optomechanical Engineering 2023 titled "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
CAD file dataset of the ISAAC AM petal re-design project
This dataset contains the .STL files of the Graph and TPMS Additively Manufactured petals. For both designs, an "As Printed" and an "As Postprocessed" version is included. These designs are detailed in the paper submitted to SPIE titled "From design to evaluation of an additively manufactured, lightweight, deployable mirror for Earth observation".
Molecular simulation trajectories and atomic interaction descriptions of 1,1,1,2-tetrefluoroethane liquids.
Data on raw atomic trajectories (5 ns) produced by DL_POLY molecular dynamics simulation package. The system model is described in the DL_F Notation, which contained chemical information of the atoms. The DL_ANALYSER Notation for Atomic Interaction (DANAI) is used to annotate the atomic interaction networks in the system, to provide an overall view of the molecular interaction behaviour. The dataset contains five different sets of simulation data, over a range of temperatures: 203K, 233K. 263K. 293K and 323K.

Data associated with the manuscript 'Efficient and stable second harmonic conversion, at the 0.5 kW-level, of a diode-pumped Yb:YAG laser'
This dataset contains the experimental data presented in the manuscript 'Efficient and stable second harmonic conversion, at the 0.5 kW-level, of a diode-pumped Yb:YAG laser'. In the manuscript, efficient and stable, type-I phase matched second harmonic conversion of a nanosecond high-energy, diode-pumped, Yb:YAG laser is presented. With the frequency doubling crystal in an enclosed, temperature-controlled holder with optical windows, an RMS energy stability of 0.49 % was achieved for a period of approximately half an hour. This resulted in 48.9 J pulses at 10 Hz (489 W) and a conversion efficiency of 73.8 %. The dataset includes data for a range of set-point temperatures (30, 40, 50 and 70 dgerees) for the two temperature-controlled (TC) holders, TC1 and TC2. 'HJ-D-P4-EM-1' is the input energy at 1030 nm. 'HJ-SHG-1W' is the residual 1030 nm energy after the frequency doubling crystal. 'HJ-SHG-2W' is the converted 515 nm energy after the frequency doubling crystal.
