High-Voltage Vacuum Feedthrough
Avalanche Energy has developed a portfolio of compact, high-voltage feedthrough products originally engineered to support the advancement of our Orbitron fusion machines. These feedthroughs reliably transmit high voltage across media while maintaining low leakage, robust shielding, and safe, serviceable operation.
Our 200 kV and 300 kV feedthroughs occupy a voltage class that is exceptionally rare in the market, offering fully shielded designs with detachable cable connection systems. Expanding the portfolio, our soon-to-be-released 50 kV and 100 kV feedthroughs deliver the same emphasis on reliability and safety in a significantly smaller form factor—approximately half the size of comparable existing products.
Designed for applications where high-voltage performance, compactness, and reliability must coexist, Avalanche Energy feedthroughs bring fusion-grade engineering to demanding high-voltage systems.

Hammerhead is a compact 300 kV high-voltage vacuum feedthrough designed for UHV-compatible systems requiring a shielded single-conductor interface across an 8 in CF flange.
The feedthrough is intended for high-voltage vacuum platforms including fusion research, accelerators, ion sources, electron-beam systems, x-ray systems, dielectric testing, and advanced laboratory instrumentation.
This work reports the physics-informed design, simulation, and experimental validation of Hammerhead, a compact vacuum bushing that has been tested up to 330 kV and used reliably at 300 kV.

Originally developed for Avalanche Energy’s fusion program, our feedthroughs are now available for industrial, scientific, and research applications requiring compact, reliable high-voltage performance.
Complete the form and our engineering team will be in touch.
All of our feedthroughs are named after shark species, partly because the machined sawtooth features on the ceramic insulator resemble shark teeth.
Hammerhead has a second naming cue: its flat, wide high-voltage connector gives the assembly a profile reminiscent of a hammerhead shark.
