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:
1. The probability that an rogue electron would set off the SiPM at any one event
1. The probability that an rogue electron would set off the SiPM at any one occurance
2. 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.

3. The number of Silicon Nuclei in the detector
3. The number of Silicon Nuclei in 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 occuring simultaneously.
