Characteristic analysis of anode panel for a ZnO nanowire cold cathode flat-panel X-ray source using Monte Carlo simulations

1、 Data content: X-ray energy spectrum of flat panel source, number of photons generated by flat panel source, photon spatial distribution data, photon angle distribution data, electron energy conversion distribution data, X-ray flux data. 2、 Data generation process: 1. Flat panel X-ray source energy spectrum: The actual energy spectrum data is measured by an energy spectrometer (X-123CdTe), and the simulated energy spectrum data is output by Geant4. 2. Number of photons generated by the flat panel source: simulated output by Geant4. 3. Photon spatial distribution data: The spatial position of particles is output by Geant4, and the number of particles in a specific area is counted by dividing the area into regions using MATLAB 4. Photon angle distribution: derived from Geant4 simulation; 5. Electronic energy conversion distribution data and X-ray flux data: simulated output by Geant4; 3、 Tools used: Geant4, Matlab;
