Programmable Electro-Mechanical Dust Dispenser for Dusty Plasma Experimental Device
An electro-mechanical dust dispenser has been designed and developed for dropping dust into the plasma in dusty plasma experimental setup. Mechanical setup of the dust dispenser has been developed and fabricated in the laboratory. The frequency of vibration and amplitude of the developed dust dispenser can be controlled electronically to ensure precise and accurate dust density in dusty plasma experiments. Drive circuits have been developed and integrated in the system that enable voltage and frequency control of the dispenser. Control signals are generated by LabVIEW software and applied to the inputs of the drive circuit. A provision to set predefined time interval for dust dropping is also incorporated in the LabVIEW program. The dust dispenser has been calibrated for dust density using laser beam and photo diode arrangement.
