The Method to Control the Size of Generated Particles from a Spark Discharger by the Ion Bombardment with the Multi-ionizing
This paper reports the effects of tremendous ions interrupting agglomeration of Nickel (Ni) aerosol from homogeneous spark generation. We made particles from spark discharger get charged with ions and take repulsive forces to interrupt the particle agglomeration. We set our experiment with clean air supply system, spark dischargers, ionizers with carbon fibers, and chambers for multi-ionizing. We designed our experimental system that we could shift the position of the ion chamber to control gaps between a spark discharger and an ion chamber. In addition, we took control the amount of ions in the ion-chamber. We used an electrometer and ion trap to evaluate the average charging number of particles. The size distribution, rate of generation, morphology, and structure of the particles were characterized by SMPS, scanning electron microscopy (SEM), transmission electron microscopy (TEM) methods. Finally, we got the information regarding the change of the size of particles as we controlled the position of the ion-chamber and the amount of ions.
