- Creation and characterization of free-standing cryogenic targets for laser-driven ion acceleration paper(Review of Scientific Instruments, 2017-07-24) Tebartz, Alexandra; Neely, David; Bedacht, Stefan; Hesse, Markus; Astbury, Sam; Clarke, Rob; Ortner, Alex; Schaumann, Gabriel; Wagner, Florian Benedikt; Roth, MarkusData used in the publication "Creation and characterization of free-standing cryogenic targets for laser-driven ion acceleration". A technique for the creation of free-standing cryogenic targets for laser-driven ion acceleration is presented, which allows to create solid state targets consisting of initially gaseous materials. In particular, the use of and the methods for its preparation as a target material for laser-driven ion acceleration are discussed. Moving in the phase diagram through the liquid phase leads to the substance covering an aperture on a cooled copper frame where it is solidified through further cooling. An account of characterization techniques for target thickness is given, with a focus on deducing thickness values from distance values delivered by chromatic confocal sensors. The target type covered in this publication was used for experiment 13210007, Vulcan, Target Area Petawatt.

Data already in existing archives have the DOI provided. New data not in an archive is provided within this DOI. The review paper abstract is: “This paper provides an up to date review of the problems related to the generation, detection and mitigation of strong electromagnetic pulses created in the interaction of high power, high energy laser pulses with different types of solid targets. It includes new experimental data obtained independently at several international laboratories. The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce. The major emphasis is put towards the GHz frequency domain which is the most damaging for electronics and may have important applications. The physics of electromagnetic emissions in other spectral domains, in particular THz and MHz, is also discussed. The theoretical models and numerical simulations are compared with the results of experimental measurements, with special attention to the methodology of measurements and complementary diagnostics. Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions, which may have promising applications.” List of data: • Figure 5: Matlab code and input file used to generate figure provided in file “Figures-5-6_Poye-A.zip” • Figure 6: Matlab code and input file used to generate figure provided in file “Figures-5-6_Poye-A.zip” • Figure 18: experimental data used to generate figure is located at: http://dx.doi.org/10.5286/edata/1 • Figure 54: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 55: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 56: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 57: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D” • Figure 58: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D” • Figure 59: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D”

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.

- Data associated with the manuscript titled 'Dual ion species plasma expansion from isotopically layered cryogenic targets', published in Physical Review Letters(2018) Scott, Graeme; Carroll, David; Astbury, Sam; Clarke, Rob; Hernandez-Gomez, Cristina; Neely, DavidThis dataset includes experimental and numerical data from the manuscript 'Dual ion species plasma expansion from isotopically layered cryogenic targets', published in Physical Review Letters. This is the data obtained during the investigation of a novel ion acceleration scheme using cryogenic targets, where a heavier ion (deuterium) exists at the target vacuum interface of a lighter ion species (hydrogen). Using this target configuration, it is found that the lighter ions interact with the heavier ions to accelerate a reduced energy spread, directional, heavy ion beam.

- Data associated with the manuscript titled “Towards terawatt-scale spectrally-tunable terahertz pulses via relativistic laser-foil interactions”(2020-07) Liao, Guoqian; Liu, Hao; Scott, Graeme; Zhang, Yihang; Zhu, Bao-Jun; Zhang, Zhe; Li, Yutong; Armstrong, C. D.; Zemaityte, Egle; Bradford, Philip; Rusby, Dean; Neely, David; Huggard, Peter; McKenna, Paul; Brenner, Ceri; Woolsey, Nigel; Wang, Wei-Min; Sheng, Zheng-Ming; Zhang, JieThis dataset includes experimental and numerical data from the manuscript 'Towards terawatt-scale spectrally-tunable terahertz pulses via relativistic laser-foil interactions'. The experimental data are obtained in the experiment titled “Intense terahertz radiation from picosecond laser-produced plasmas” (Application No.: 16110035, PI: David Neely), performed at Vulcan TAW. In this experiment, we demonstrate efficient production of terawatt (TW)-level THz pulses from high-intensity picosecond laser-foil interactions, and find the THz spectrum can be manipulated effectively by tuning the laser pulse duration or target size. A general analytical framework for THz generation is developed involving both the high-current electron emission and a time-varying electron sheath at the target rear, and the spectral tunability is found to stem from the change of the dominant THz generation mechanism. The THz radiation is applied to quantitatively diagnose the electron emission and the transient sheath, in good agreements with experimental measurements.

- Dataset summarising experimental results on the performance of a quartz polarisation rotator at low temperature(2019) De Vido, MariastefaniaThis 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.

- EMP generated by high intensity ultrashort laser-solid interaction on the Vulcan Petawatt Data set(2017-02-28) Carroll, David; Read, Margaret; Selwood, Matthew; Scott, Graeme; Neely, DavidThe data provide is that used while generating a time-frequecny analysis method for EMP (electromagnetic pulses ) generated from a high intensity laser-solid interaction. The data set includes additional data where the parameters of the laser are varied. This data is voltage-time oscilloscope traces from Moebius loops, which respond to the rate of change of magnetic field, and are the same as used by M.J. Mead et al (Rev. Sci. Instru. Vol75, pp4225-4227, 2004) and are connected to a Tektronix 15GHz oscilloscope. The cables used are double sheathed coaxial cable which limits signal frequencies to less than 4Ghz. Two different targets were used, made of gold or glass. The gold target was 100 micron thick across 500 micron diameter hole in a copper substrate 100 micron thick that is 3 mm by 7 mm. The glass target was Borrosilicate Glass that was 3mm thick by 3mm tall and 0.5mm wide. This data was generated during a Vulcan Petawatt laser experiment February 2017 (13210073).
- Escaping Electron from Intense Laser-Solid Interactions as a Function of Laser Spot Size(2017) Rusby, Dean; Neely, DavidA high powered laser was defocused to observe the effect that this has on the escaping electron population. The data was recorded on Image plate and saved as a .Fit file. Analysis of the diagnostic was conducted using GEANT4 and PIC simulations regarding the self-focusing of the laser on the front surface were also done. Here is the abstract: The interaction of a high-intensity laser with a solid target produces a high-energy distribution of electrons that pass into the target. These electrons reach the rear surface of the target that creates strong electric potentials that restrict the escape of many of the electrons. The measurement of the angle, flux and spectra of the electrons that do escape is able to give insights to the initial interaction. Here, the escaping electrons have been measured from interactions with intensities from 〖10〗^(17-20) W/cm2, where the intensity has been reduced by increasing the size of the focal spot. A curved diagnostic with multiple layers of differentially filtered image plate measures the escaping electrons from the target. An increase in electron flux is observed at an intensity of $ $ which corresponds to a defocus of 100 µm. The peak temperature of the electron distribution is also calculated and found to be relatively constant as a function of laser spot size.
