Supplementary Materials ======================= Corresponding manuscript: "Laser-solid interaction studies enabled by the new capabilities of the iP2 BELLA PW beamline" by Sahel Hakimi, Lieselotte Obst-Huebl, Axel Huebl, Kei Nakamura, Stepan S. Bulanov, Sven Steinke, Wim P. Leemans, Zachary Kober, Tobias M. Ostermayr, Thomas Schenkel, Anthony J. Gonsalves, Jean-Luc Vay, Jeroen van Tilborg, Csaba Toth, Carl B. Schroeder, Eric Esarey, and Cameron G.R. Geddes (2022) Structure of this Archive ------------------------- This archive is structured as follows in sub-directories: - `WarpXsource/`: the simulation source code, build instructions/documentation and references - `WarpXDataAndInputs/`: the simulation inputs, submission scripts, and representative output - `FigureDataAndScripts/`: the analysis scripts and, where applicable, processed data for individual figures Note that raw data output of simulations is approximately 180 TByte per simulation and can thus not easily be shared in this data archive. Instead, we make all source code, documenation and build instructions, selected processed/reduced data, and relevant analysis scripts available to ensure reproducibility of the raw data basis. Please see the individual subdirectories for further `README.txt` files. Contacts -------- For general questions about the publication and data archive, please contact the corresponding authors.
