• Can Transient Phenomena Help Improving Time Resolution in Scintillators?

Publication Year: 2014, Page(s):229 - 234
Cited by:  Papers (19)
| | PDF (645 KB) | HTML

The time resolution of a scintillator-based detector is directly driven by the density of photoelectrons generated in the photodetector at the detection threshold. At the scintillator level it is related to the intrinsic light yield, the pulse shape (rise time and decay time) and the light transport from the gamma-ray conversion point to the photodetector. When aiming at 10 ps time resolution, flu... View full abstract»

Publication Year: 2014, Page(s):252 - 256
| | PDF (583 KB) | HTML

A phenomenological approach is applied to derive the light yield of a scintillator as a function of the rates of various radiative and nonradiative linear and nonlinear processes that may occur within the track. The effect of evolution of the excitation concentration within the track is studied. It is found out that an exciton formation time less than a ns can lead to minimizing the nonproportiona...

We study the low temperature contribution to delayed recombination decay in several complex oxide scintillating crystals. We experimentally test the previously suggested hypothesis that the losses of fast scintillation light even at the lowest temperatures can be due to quantum effects. The results obtained for several material systems confirm that quantum tunneling between the luminescence center... View full abstract»
