Fusion reactor
Designing an inertial electrostatic confinement fusion reactor and doing some fun experiments in it
During middle and high school, I built a variation on the design for a Farnsworth Fusor, which is an inertial electrostatic confinement device that can act as a weak neutron source by fusing small quantities of deuterium ions. I used my reactor to perform a series of rudimentary experiments for Intel ISEF which demonstrated a method of neutron collimation by using an additional ion gun to impart a velocity differential in the deuterium ions, skewing the momentum distribution of the neutrons produced in the fusion reactions. Here are a couple of old photos of the reactor.
