Figure 1
Reduction in the number of X-rays counted as the time difference between two successive pulses is decreased. The horizontal axis is time and the vertical axis is the signal. The signal is given by the sum of the individual pulses (shown as dotted lines). UL is the upper-level setting for the SCA and LL is the lower-level setting. The arrows indicate pulses that are successfully counted. A pulse is counted when the signal goes from below to above LL and then returns below LL again without having gone above UL.
