Stainless Steel Proximity Experiment

Current pulsed through a copper coil will generate a magnetic field. When this occurs inside a stainless steel vacuum chamber, the resultant magnetic field will be modified due to Faraday’s law of induction. Using hall probes, as well as Bdot probes these effects can be measured.The goal of this research is to explore these effects, to help determine how to minimize the impact it has on the overall experiment. Furthermore, this information will help advance fusion research being conducted by Bryn Mawr in collaboration with Swarthmore's SSX lab. It is expected that as the distance between the copper coil and stainless steel chamber is increased, the effects on the magnetic field will decrease.

Researchers have yet to achieve a self-sustaining fusion reaction in which the amount of energy put in is less than that being produced. Bryn Mawr and Swarthmore  aim to develop new modules in which to accelerate and compress plasma plumes with relatively low energy input and high stability. Hall probes and Bdot probes are used to calculate the time of flight in order to know how fast the plasma is being accelerated. The use of the stainless steel is both a practical, and cost efficient design that will be more accessible for future research.
