Detector Simulation Projects

UCGretina

… is a Geant4 simulation of the Gamma Ray Energy Tracking Array (GRETA) – an array of gamma-ray tracking detectors used in nuclear physics experiments at ANL, the NSCL, and FRIB.

(Top panel) Measured (full circles) and simulated (open circles) photopeak efficiencies of the 12-quad standard NSCL configuration of the GRETINA array. (Bottom panel) Relative discrepancies between simulated and simulated and measured efficiencies.

UCNa

… is a Geant4 simulation of the Bicron 2M2 sodium iodide (NaI) scintillator detectors we use in our advanced laboratory courses for gamma-ray spectroscopy and cosmic-ray observation.

Ray Saunders collected source spectra and ran UCNaI simulations in Spring 2021. The simulations systematically over-predict the efficiencies. The green and yellow show simulations with reduced crystal volume.
