Electron sources

The Xelera team has been designing and building electron sources for several decades. The process for building an electron source includes:
  • Electromagnetic design
  • Beam dynamics design
  • Vacuum system design and fabrication
  • Integrated mechanical design
  • RF design and electronics assembly. 
Over the course of their careers, members of the Xelera team have built devices for Brookhaven National Laboratory, Cornell University, and Thomas Jefferson National Accelerator Facility.

Xelera Tgun installed at JLab

Xelera Research LLC, in collaboration with a team at JLab, designed, built, and tested a thermionic electron source (Tgun) to drive a magnetized electron cooler for a future electron-ion collider project. This device was delivered to JLab in July of 2019, and achieved first beam in December 2019. This work was funded through the U.S. Department of Energy SBIR program.

Electromagnetic design

Mechanical and Vacuum design

Nearly all of the mechanical and vacuum system is designed and built in house.  

Beam dynamics design and optimization

6D Particle tracking simulations in 3D fields, including all of the relevant beam dynamics effects, are performed for the complete system. Parallel optimizations are performed on top of these simulations for desired beam qualities, such as emittance or magnetization preservation.

RF components design and fabrication

RF components, such as this thermionic cathode feed, are designed, machined, and tested in house.
