Excitation of Gould-Trivelpiece(TG) mode by an electron beam via Cerenkov interaction in a magnetized dusty plasma cylinder is studied considering the effect of variation in the size and number density of dust grains.The unstable wave’s frequency increases with wave number and (relative density of negatively charged dust grains). However, the growth rate decreases with size and density of dust grains due to dust charge fluctuations. Our work may advantageous in plasma processing of material experiments because dust appeared to be key source of contamination during material manufacturing.
