Since the dark rate is the rate at which the SiPM avalanches, its value depends on 3 factors:
Since the dark rate is the rate at which the SiPM avalanches, its value depends on 3 factors:
−
* The probability that an rogue electron would set off the SiPM at any one occurrence
+
* The probability that an electron in a silicon crystal lies in the conduction band at temperature t
−
* The Rate of Scattering, or the average amount of time that is required for an electron to impact a silicon nucleus, redistributing energy randomly among the two entities.
+
* The average rate at which a valence band electron scatters by hitting a defect or a phonon in the silicon crystal
−
* The number of Silicon Nuclei in the detector
+
* The number of valence electrons in the active region of the detector
−
The dark rate is calculated by multiplying these three factors together. It is the probability of an event, multiplied by the rate at which the probability is calculated, then multiplied by number of places that this is occurring simultaneously.
+
The dark rate is calculated by multiplying these three factors together. It is the probability of an state, multiplied by the rate at which electrons can enter that state, then multiplied by number of electrons that are participating simultaneously.
