D: ENI is an indication of the photon-limited signal-to-noise ratio. It refers to the amount of light in watts to produce a signal-to-noise ratio of unity in the output of a photomultiplier tube. ENI = where q= ldb = g= ∆f = S= 2q·ldb·g·∆f S Electronic charge (1.60 × 10-19 coulomb). Anode dark current (after 30 minutes storage) in amperes. Gain. Bandwidth of the system in hertz. 1 hertz is used. Anode radiant sensitivity in amperes per watt at the wavelength of peak response. E: The rise time is the time for the output pulse to rise from 10 % to 90 % of the peak amplitude when the entire photocathode is illuminated by a delta function light pulse. F: The electron transit time is the interval between the arrival of delta function light pulse at the entrance window of the tube and the time when the anode output reaches the peak amplitude. In measurement, the whole photocathode is illuminated. G: Also called transit time jitter. This is the fluctuation in electron transit time between individual pulses in the signal photoelectron mode, and may be defined as the FWHM of the frequency distribution of electron transit times.
