Dark count rateとは
Web30oC. Figure 6 illustrates the decrease dark count rate as a function of temperature. Though the standard dark count rates test is performed at -30oC, figure 5 reveals that there is little advantage gained by cooling below -10oC.-Figure 6-(Note: The dark count rate is determined by recording the total number of dark counts between WebThe bias-current dark count rate reveals a typical slope change at a critical current, which in this particular case is 17µA. For bias currents below 17µA, the dark count rate slightly …

WebThe dark count can be obtained by integrating the rate of carrier generation between (w 2 –w 1) and w 1. As a result, the dark count generated by these three effects can be estimated by using the following equation: where P tr (x) is the probability of carrier avalanche triggered at position x in the depletion region and is expressed below.

WebThe dark count rate of the detector sets a limit to the sensitivity of a photon counting system. The dark count rate of a PMT depends on the cathode type, the cathode area, and the temperature. The dark count rate is highest for cathodes with high sensitivity at long wavelengths. Typical dark count rates for the commonly used photoeathodes are ... WebJul 1, 2015 · From Fig. 3 one can conclude that the effective dark count rate is reduced 10× by lowering the temperature by 30 K. Operating the 200 µm diameter detection chip at a room temperature, gating it at the rate of 10 Hz and biasing it 2.5 V above its breakdown voltage its effective dark count rate is typically several MHz.
