Question on determination of 4 components of light emission time for ZnS(Ag) scintillator in Geant4.
Hi everyone!
We are working with inorganic ZnS(Ag) scintillators with neutron capturing additives (Li, B).
If you look at articles about scintillators, you will notice that the amount of components of light emission is different. For example, in the article “Study of luminescence and scintillation properties of ZnS-Ag/⁶LiF scintillator in the temperature range 7-295 K” by V.B. Mikhailik, S. Henry, M. Horn, H. Kraus, A. Lynch, M. Pipe, the parameters of ZnS(Ag)/⁶LiF decay kinetics were fitted using three exponential functions. Similarly, in “Investigation of the response of the ZnS(Ag)/LiF thermal neutron detector using digital pulse processing” by F. Pino, L. Stevanato, D. Chester, G. Nebbia, L. Saggio-Bohus, and G. Viesti, three decay components were determined for neutron-induced signals. In addition, in the paper Carel W.E. van Eijk “Development of Inorganic Scintillators” three decay time components were also observed for some inorganic scintillators such as LiBaF₃.
As for our studies, we observe up to four light emission components for neutron events.
When specifying the scintillator properties in Geant4 in the DetectorConstruction.cc file, only two components (fast and slow) for the light emission time can be defined. We would like to know if four components for light emission time can be defined in Geant4, and if so, how can this be implemented? Is there any way to add additional components for more accurate simulation?
Any tips or examples will be appreciated!
Thank you in advance for your help.
