The duration of the amplified signals is, in essence, the dead time of the channel. (Pulses with significant overlap are difficult to distinguish.) The lower bound of the pulse width is set by the scintillator. The BCF-20 intended for use in the microscope has a decay time of 2.7 ns. A somewhat stricter restriction is set by the sampling rate of the ADC - 250 MHz. A rough (and vague) guideline of 15 total signal duration has been observed during the design.
