There are 3 different ways to identify particles. For larger Z particles (Z≥3), the energy of the Si detector is plotted versus the CsI detector. The energy of the 1st Si detector versus the energy of the 2nd Si detector can be plotted for supertelescopes.

    For small Z particles (Z≤3), the fast component of the CsI signal can be plotted as a function of slow components. The fast component is 400 ns long and includes the rise and peak (previous measurements started at the peak). The slow component starts 1 μs after the fast starts and is 1 μs long.
