英文摘要Examples are given which prove the ICARUS detector quality through relevant physics measurements. We study the mu decay energy spectrum from a sample of stopping mu events acquired during the test run of the ICARUS T600 detector. This detector allows the spatial reconstruction of the events with fine granularity, hence, the precise measurement of the range and dE/dx of the mu with high sampling rate. This information is used to compute the calibration factors needed for the full calorimetric reconstruction of the events. The Michel rho parameter is then measured by comparison of the experimental and Monte Carlo simulated mu decay spectra, obtaining rho = 0.72 +/- 0.06 (stat.) +/- 0.08 (syst.). The energy resolution for electrons below similar to50 MeV is finally extracted from the simulated sample, obtaining (E-meas(e) - E-MC(e))/E-MC(e) = 11%/rootE[MeV] +2%.
