True Coincidence Summing

P-TReCK-TCS is an extension of P-TReCK that simulates γ-γ true coincidence summing (TCS) effects in gamma-ray detector responses. Specifically, TCS occurs when multiple ionizing radiations, such as gamma rays, are emitted nearly simultaneously from a radionuclide decay cascade, leading to energy summation during detection. This summation can distort the gamma-ray spectra and significantly affect peak height measurements and detection efficiency, regardless of the activity or intensity of the radioisotope. P-TReCK-TCS enables users to accurately model and analyze detector spectra while accounting for γ-γ TCS effects, providing valuable insights for gamma-ray detection applications, particularly in situations where TCS significantly impacts measurements.

Key Features of P-TReCK-TCS

  • Redesign and Enhanced Accuracy: This extension is a redesigned version of the original software framework. It effectively simulates radionuclide decay processes and tracks decay histories. Furthermore, it aggregates energy deposition events within detectors to model γ-γ TCS effects in spectral analysis.
  • Customizable Nuclide Database: The TCS module uses gamma-ray decay cascade data from the Nucleide-Lara database (LNHB). Users can also add custom nuclides to enhance their simulations.
