Angle-resolved annihilation-photon correlation factors for an annular NaI(Tl) detector
Authors: Ayush Priyadarshi, Rahul Chauhan, Asit Srivastava, and G. Anil Kumar

My role: First and corresponding author
This manuscript presents a full-interval, angle-resolved calculation of annihilation-photon correlation factors for an annular NaI(Tl) detector. I corrected and extended an earlier unpublished mathematical treatment, completed the Geant4 analysis, implemented and validated the numerical calculation, prepared the figures, developed the public software package, and wrote the complete manuscript.

A Python-based Tool for Automated Geant4 Simulations of Scintillation Detectors
Authors: Ayush Priyadarshi, G. Anil Kumar, Kavish Madhan, and Virender Ranga
Venue: IEEE Nuclear Science Symposium 2026
Status: Accepted for poster presentation
This paper presents a compact Geant4–Python simulation-analysis tool for reproducible scintillation detector response studies. The tool connects a configurable Geant4 C++ simulation backend with Python automation for macro generation, simulation execution, ROOT-file validation, deposited-energy spectrum generation, count extraction, and summary table generation.
The workflow is demonstrated using Cs-137 simulations across solid cylindrical, hollow cylindrical, and near-4π soccerball-style detector geometries. High-statistics validation runs on the PARAMGanga supercomputing facility demonstrate that the same workflow can be extended toward larger detector-response simulation campaigns.

- Campaign execution
- ROOT-file validation
- Deposited-energy spectrum generation
- Peak-count extraction
- Total non-zero count extraction
- CSV/table generation
- Geometry-dependent detector response studies
This repository forms the software basis of my master’s thesis and first-author IEEE NSS 2026 poster presentation.
Thesis
A Python-Assisted Geant4 Workflow for Automated Scintillation Detector Response Simulations
Degree: Integrated BS–MS Physics
Institution: Indian Institute of Technology Roorkee
Supervisor: Prof. Anil Kumar Gourishetty
Period: 2025–2026
My master’s thesis developed an automated Geant4–Python workflow for campaign-level scintillation detector response studies. The work focused on reproducibility, traceability, simulation automation, ROOT-based analysis, and detector-response comparison across materials and geometries.
