  Observations of quantum turbulence in pure superfluid 4He in a rotating
container are reported. New techniques of large-scale forcing (rotational
oscillations of the cubic container) and detecting (monitoring ion transport
along the axis of rotation) turbulence were implemented. Near the axial walls,
with increasing forcing the vortex tangle grows without an observable
threshold. This tangle gradually develops into bulk turbulence at a
characteristic amplitude of forcing that depends on forcing frequency and
rotation rate. At higher amplitudes, the total vortex line length increases
rapidly. Resonances of inertial waves are observed in both laminar and
turbulent bulk states. On such resonances, the turbulence appears at smaller
amplitudes of forcing.
