The paper reports on detailed studies of an anisotropy of the fusion-produced neutrons emitted from the modernized PF-360 facility, which has been operated with a pure deuterium-gas filling, without and with some additional solid-state targets containing deuterium atoms. Under standard operational conditions, anisotropy of the neutron yield from the PF-360 facility is similar to that observed in other PF devices. For the first time the neutron emission anisotropy has been measured in the PF experiments performed with a planar cryogenic target covered with a heavy-ice (D2O) layer. Changes in the Yn(F)/Yn(90°) ratio, particularly for angles F = 0-60°, have been explained by the known features of the angular distribution of fast deuterons.
