Abstract

This project focused on the how the horizontal confinement of a dust particle changes based on pressure and cutout size. When a cutout is placed on the bottom electrode a potential well is created from the change in the shape of the electric fields. This provides the horizontal forces needed to keep the particle from falling off the electrode. Using several programs, a dust particle's position was tracked though several frames, converted to meters, and used to determine U. A quadratic curve was then fitted to the U vs. x graph to determine the confinement coefficient k. From the analysis, it was determined that U assumes a parabolic form, which agrees with different proposed theories. It was also determined that k increases as pressure increases for the 1/4 inch cutout.
