Data 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 and metadata for IoP publication (doi:10.1088/1742-6596/713/1/012006)
(Central Laser Facility, STFC, 2014-10-08) Astbury, Sam
The data and metadata supplied document the figured and resources used to publish the following paper: "In-situ formation of solidified hydrogen thin-membrane targets using a pulse tube cryocooler" (Sam Astbury et al. 2016) The paper gives an account of the Central Laser Facility's work in producing a cryogenic hydrogen/deuterium targetry system using a pulse tube cryocooler. The system was fielded in the Central laser Facility (CLF) in Harwell, Oxford UK and used to grow thin-membranes of deuterium which was then shot with a Petawatt-power laser. The paper outlines the method and system which was built in order to deliver such targets to the laser and the data supplied focusses on the parameters necessary to achieve this, supplied in the "All cryologs (up to 8.10.2014)" as well as phase diagram resources and leak testing data.
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, David
This 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. Please see the file named ‘description_of_data’ in the root directory of the attached zip file for a detailed discussion of the data contained therein.
Data used in the manuscript “Cherenkov radiation-based optical fibre diagnostics of fast electrons generated in intense laser-plasma interactions”
(2017-06) Liu, Hao; Liao, Guo-Qian; Zhang, Yi-Hang; Zhu, Bao-Jun; Zhang, Zhe; Li, Yu-Tong; Scott, Graeme G.; Rusby, Dean; Armstrong, Chris; Zemaityte, Egle; Carroll, David C.; Astbury, Sam; Bradford, Phill; Woolsey, Nigel; McKenna, Paul; Neely, David
The data is from fiber Cerenkov diagnostics, which is taken in intense laser-plasma interactions experiments. This work has been illustrated in the paper “Cherenkov radiation-based optical fibre diagnostics of fast electrons generated in intense laser-plasma interactions”. The data is taken to prove that it is valid to use optical fiber to measure fast electrons generated in intense laser-plasma interactions. The creation method and description of the data can be find in the manuscript.
