Abstract :
Plasma expansion from a hot dense source to a low pressure environment is relevant to many subjects in science [1], [2]. In this contribution we present the expansion of dusty plasma inside a plasma sheath of an radio-frequency (rf) discharge using specifically designed segmented electrode and estimate the charge of particles at the initial stage of the expansion.
