Tandem accelerator test. (A) Histograms of the glitch amplitudes in 2 h of integration time for low amplitudes (0 V – 0.1 mV). (B) Histograms of the glitch amplitudes in 2 h of integration for high amplitudes (greater than 0.1 mV). (C) Glitch template built by stacking all the events of the first family centered at 45 μV (blue) and the family centered at 0.15 mV (red). Both templates show the same fast time-constant τ (4 ms), and the blue template shows a slower time-constant (about 20 ms) with an amplitude relative to the peak of few percent.
