Abstract : The instability of ion-acoustic wave in quantum dusty plasma propagating in a cylindrical waveguide filled with strongly magnetized plasma consisting of oblique streaming of holes and stationary negatively charged dust particles has been theoretically investigated using the quantum hydro-dynamical (QHD) model which includes both quantum statistical effect and the quantum diffraction effect. It is shown that ion acoustic wave become unstable in the bounded quantum dusty plasma. The growth rate of unstable wave depends on the stream velocity of holes, quantum diffraction parameter, charge imbalance parameter, inclination of stream velocity and dimension of cylindrical wave guide. Moreover, the phase velocity of the wave depends on the plasma parameters and the dimension of wave guide. Growth rate of the instability and phase velocity of wave in bounded quantum plasma are shown graphically and discussed.
