Fig. 7: Individual pulse height per-channel pulse-height spectra acquired by the Multi-Channel Analyzer (MCA) in Analog-to-Digital Converter (ADC) channels for a single-stage muography experiment with one acrylic cube.
From: Laboratory-scale muography experiments to estimate density and saturation in porous media
Shown are PMT pulse amplitudes from each detector channel for events passing the fourfold coincidence condition; these represent signal amplitudes rather than deposited energy. The figure shows the counts of detected events for each amplitude signal (pulse height). A Gaussian fit (red curve) is applied to estimate the central muon peak, with upper and lower bounds (μ ± 2σ) indicated by vertical dashed lines. The estimated minimum and maximum pulse height ranges are specified for each channel filtering, corresponding to the valid signal window.
