Compact SRF Accelerator

Technology Summary

Accelerators developed for science now are used broadly for industrial, medical, and security applications. More than 30,000 accelerators touch more than $500B/yr in products producing a major impact on our economy, health, and well-being. Industrial accelerators must be cost-effective, simple, versatile, efficient and robust. Many industrial applications require high average beam power.

The Invention

Exploiting recent advances in Superconducting Radio Frequency (SRF) cavities and RF power sources as well as innovative solutions for the SRF gun and cathode system we have developed a design for a compact SRF high-average power electron linac. Capable of >250 kW average power and continuous wave operation, this accelerator produces electron beam energies up to 10 MeV.


Small and light enough to mount on mobile platforms, Fermilab Compact SRF accelerators enable new in-situ environmental remediation, in-situ crosslinking of materials, and security applications. More importantly, this accelerator will be the first of a new class of simple, turn-key SRF accelerators.
