University of WI HSX Stellarator Project

JP Pattern assisted in the construction of a Helically Symmetric Experiment stellarator with the University of Wisconsin. A stellarator is a machine that is designed for the magnetic confinement of plasma. The goal of these devices is to achive an endless, low cost ,supply of electrical energy without harmful by-products.

For more information regarding this project please visit the University of Wisconsin (www.hsx.wisc.edu) HSX Under Construction

HSX Design

StellaratorThe vacuum vessel was constructed in segments. These segments were initially explosion formed inside the cavity of a 9 layer steel tool.


Vessel sections were then trimmed via a 5-axis laser to proper dimension. Holes for instrumentation were also added. The sections were then welded together.

CoilMagnetic coils were formed on fixtures with roller-coaster shapes to achive the desired magnetic field necessary to establish plasma confinement.

steel frameCoils were then positioned inside a steel frame for placement around the vacuum vessel. These coils produce the magnetic field for plasma containment.
