Ever wondered what a discharge experiment in action looks like? Well after the gas leaves the pulsed expansion nozzle, it passes through a discharge nozzle. This nozzle looks like the schematic in Figure 1, with two copper electrodes that are separated by some distance. These two electrodes are what impart the energy to the gas that we are working with to create a plasma. From here the molecules in our expansion are broken up and recombine together to form new molecular species. Check out Figure 2 to see a real life example of the discharge nozzle in action.
