Abstract

We built a Farnsworth-Hirsch fusor in order to study neutron emission from nuclear fusion. Its construction involved a mechanical roughing pump, an oil diffusion pump, a vacuum chamber, a high negative-polarity power source, and a bubble dosimeter neutron detector. To determine the efficiency of the fusor we look at the neutron emission flux and the power input. We then compare those results to obtain a ratio of power input versus the power output by the fusor.
