The paper reports on first neutron-emission experiments carried out with the modernized PF-1000 facility. Current sheath dynamics was investigated by means of high-speed cameras. Based on smear pictures, which were taken through a narrow radial slit, the compression velocity was determined. The total neutron yield and angular distribution anisotropy were measured with four silver-activation counters placed at different angles to the electrode axis. It was found that for each initial D2-filling pressure value, with an increase in the charging voltage (V0), the neutron yield increases to some maximum and with further increase in V0 the neutron emission decreases. The highest neutron yield registered so far has been 2·1011 per shot. The neutron emission anisotropy seems to be lower than that registered in other plasma-focus experiments. The neutron energy spectra, which were measured by means of a scintillating probe in the upstream direction, have been shifted toward lower energy (2.2-2.3 MeV).
