| الوصف: | The ICARUS time projection chamber can yield sound information on B solar neutrinos. Owing to the high-energy resolution and the good capability of event reconstruction it can make a contribution to our understanding of neutrino 0168-9002/00/$ -see front matter 2000 Elsevier Science B.V.

Moreover, the MSW oscillation probability for sterile and active neutrinos can be well studied because both elastic scattering by electrons and absorption reaction on argon nuclei can be measured independently. The main problem in detecting the low-energy neutrino interactions arises from the environmental radioactivity. In the present work we study by Monte Carlo simulation the topology and the rates of the events, induced by neutrinos and background neutrons, in a 470 t ("ducial mass) liquid-argon TPC detector. For neutrino interactions we use the standard solar model BP98 and the recent experimental con"rmation of the shell model computation of absorption cross section. The noise is estimated from new data on natural neutron background, collected in the hall C of the Gran Sasso laboratory. It is con"rmed that, with a relatively modest neutron shielding and particular o!-line event triggers, the weight of spurious events can be made to have little in#uence on the ICARUS solar neutrino measurement. Indeed, we expect 6 (26) background events per year in the 212 (759) elastic scattering (absorption reaction) sample. |
