The electronics in the MIFEDS (magneto-inertial fusion electrical discharge system) used in magnetized plasma experiments have been extensively redesigned to improve reliability and make the unit more user friendly. The updates include new storage capacitors that quadruple the stored energy, an updated charging power supply, and a new pressurized metal-ceramic triggered spark gap. All the components are housed in an aluminum monocoque enclosure and connected to the magnetic coils via a coaxial vacuum transmission line. The MIFEDS operations are controlled with a laptop-based, custom-built graphical user interface via a compact control “suitcase.” Shown is Larry Folnsbee finishing up the assembly.
