摘要：

The aim of the NEMO collaboration is to search for neutrinoless double-beta decay and thus to investigate physics beyond the Standard Model. The expected sensitivity for the effective neutrino mass is on the order of 0.1 eV. The NEMO3 detector will be completed and ready to start measurements by the end of the year 2001. Since June 2000, three contiguous sectors have been operating in the Frejus Underground Laboratory (France). This trial run has provided a check on the functionality of the counters and the tracking device. The status of the experiment, the results obtained with the three sectors, as well as expected backgrounds and source radiopurity are presented.
