[Dataset] A Particle-In-Cell Code Comparison for Ion Acceleration: EPOCH, LSP, and WarpX

Here we share simulation results comparing three Particle-In-Cell (PIC) codes: <br> - EPOCH (using the normal random seed and 20 additional runs with different seeds),<br> - LSP (using both explicit and implicit modes labeled LSP_E and LSP_I), <br> - WarpX Notes:<br> - Since the previous upload, the WarpX particle energy distributions have been updated to include the virtual (py) momenta<br> - LSP makes calculations using a virtual dimension of 1 cm while the other codes use 1 meter<br> - See the corresponding manuscript for full problem description and context Explanation of Folders/Files:<br> -&gt; Energy_Diagnostics<br> - This directory has files containing field and particle energy information for each code<br> - Various file formats are used, see headers for information on data format<br> - As mentioned above LSP uses a different convention for the virtual dimension size, so the outputs must be multiplied by 100 for comparison <br> <br> -&gt; Particle_Spectra<br> - This directory contains calculated energy distributions of forward going particles for the various runs. <br> - The file number multiplied by 10 fs gives the simulation time (e.g. 30_Spectrum.dat is 300 fs)<br> - In the files, the first column is the energy bin (MeV), the second is total ion charge (C), and third is electron charge (C)<br> - As mentioned above LSP uses a different convention for the virtual dimension size, so the outputs must be multiplied by 100 for comparison<br> <br> -&gt;Simulation_Input_Files<br> - EPOCH and WarpX simulation input decks (input files) are included here <br> - LSP is a commercial code. If you have access to the code and are interested in the input files, please contact us. <br> <br> -&gt; EPOCH_20_Runs_Density_Map<br> - An array of the simulation space denoting whether at least one of the 20 additional EPOCH simulations had non-zero ion density for the corresponding plot step (every 10 fs)<br>
