Experimental and simulation dataset for a Multi-modal imaging detector proof of concept and associated paper

Abstract

Dataset associated with the Review of Scientific Instruments article titled "Simultaneous co-axial multi-modal inspection using a laser driven x-ray and neutron source" published in 2024. Dataset includes all relevant raw data, a detailed shotsheet providing necessary metadata for the experimental work, python files to generate each figure in the manuscript, and simulation input decks used in the manuscript.

The directory "./data/" contains image files (.tif) generated with a Hamamatsu Image Intensifier system and neutron time-of-flight traces (.csv) generated with a PMT and Teledyne Lecroy oscilloscope, and the shotsheet (.xlsx) with pertinent experimental information. Each figure (excluding figure 3, which is an experimental layout diagram) is generated using python (version 3.8.5) and associated standard scientific libraries (numpy, matplotlib, PIL, pandas, scipy), the files to generate each figure have been included in the DOI.

Figure 6 includes simulation data generated with G4 Beamlines version 3.08, the necessary input deck is included (./simulation/TAW_bimodal_detector.g4bl) as well a directory for the neutron simulation (./simulation/3MeV_neutrons/) and x-rays (./simulation/200keV_x-rays/), within each directory is the necessary "trackFile.txt" which defines the spectral content of the each simulated beam and "totalEnergy.txt" which is the output file from the simulation. The totalEnergy.txt for each simulation is read by the fig6_generate.py and contains two columns with the detector volume (world, pixels 1-3250, etc.) and the energy deposited in each.
