Description
The PANDORA (Plasmas for Astrophysics, Nuclear decay Observation and Radiation for Archaeometry) project features magnetized plasmas in compact ECR traps as experimental environments for fundamental astrophysics and nuclear physics. A new algorithm for X-ray imaging in Single-Photon Counting mode was adopted, enabling space-resolved spectroscopy for magneto plasma properties investigations (e.g. local thermodynamic parameters, confinement dynamics). Both the diagnostics setup and the algorithm were developed over ten years and tested multiple times on ATOMKI Laboratory’s 2nd generation ECRISs. A step forward in the algorithm optimization was recently made via an AI-based MATLAB model to yield faster analysis of plasma spectra enhancing energy and spatial resolutions, maximizing the S/N ratio. While well-established on 2nd generation ECRIS, the technique has never been applied to a 3rd generation one. To address this challenge, we developed a high-fidelity Geant4 simulation of the LBNL’s VENUS ion source. The simulations serve as a critical tool to predict the expected counting rates and quantify the X-ray fluxes, based on volumetric spectra, thus ensuring the CCD safety against saturation or ionizing radiation damage. An experimental X-ray imaging campaign on VENUS is scheduled, and preliminary results will be presented and compared with the simulation aiming to establishing safe operational limits—through RF frequency, power, magnetic field, and pressure parameter scans.
