Would the metal I use for the parallel plate capacitor matter as none of the formulas seem to take it into their equations only the permittivity of the region between the two plates?

Thank you for your response. What voltage source are you using for your experiments and and what material would be best for the array of pins to get the highest charge density or is the material irrelevant as long as it is a conductor?

Hello, I am planning on building an electrostatic ion accelerator by having a tube with parallel plate capacitors to have a negatively charge plate facing one direction and an electrode to generate the ions for repulsion. now my question is if I have the wire from the negative side of my high voltage source split so as to branch between the capacitor and the electrode would this decrease the voltage to either source? and my second question is what are ways to increase the charge density created by the corona from the electrode aside from just increasing the voltage into the electrode.
