The WArP Experiment: A Double-Phase Argon Detector for Dark Matter Searches
Figure 6
((a), (b)) Total reconstructed waveform (sum of 37 PMTs, (a)) and integrated signal (b) for an -induced event in the inner detector. ((c), (d)) The same for an electron event. The difference in the relative weight of the fast and slow light components in the two classes of events is clearly visible in the rise times of the integrated signals, with the upper one being much smaller than the lower one (i.e., dominating fast component for the -particle event).
