Accelerator Systems

Beam diagnostics, RF components, accelerator structures, controls, and data acquisition


FAR-TECH is capable of supplying complex accelerator systems that may use one or more of our standard products, custom-developed components, and components sourced from outside suppliers. In addition to our deep knowledge of accelerator physics, we rely on an inter-disciplinary approach and our strengths in project management and systems engineering in order to deliver the system on time and under budget.

Examples of systems we have delivered include:

  • A buncher cavity for an industrial linac complete with RF power source, beam focusing magnets, and control and detection electronics.
  • A linac system currently installed at a university laboratory including a 10 MeV S-band linac structure, a variable power divider phase shifter and directional coupler, and all waveguide components needed to perform the upgrade.

Components that we have designed and are capable of supplying include:

Accelerator Structures: FAR-TECH is capable of handling the design and fabrication of high-power accelerator structures from start to finish, including RF design, thermal and multipactor simulation, mechanical design, bead pull testing and structure tuning, and RF conditioning.

RF Components: We have expertise in designing fixed and variable RF power dividers/combiners for a variety of frequencies in both co-axial and waveguide geometry. These components are used when standard off-the-shelf components are not available, or to minimize the system's physical footprint.

Beam Diagnostics: FAR-TECH has a long history of making state-of-the-art beam diagnostics, including cavity BPM and beam quadrupole monitor (BQM) detectors. These solutions, as well as conventional diagnostics such as OTR and phosphor screens can be added to an accelerator design.

Simulations: Our scientists have expertise in simulating many different types of particle beam scenarios using tracking codes and particle-in-cell (PIC) analysis. We are capable of performing RF gun and emittance optimization studies, DC gun and ion source simulations, and general particle tracking studies, as well as energy deposition and wakefield studies. The analysis can be driven by a large-scale CAD model of the entire accelerator system, which is used to export sub-geometries as inputs to various codes.

Controls and Data Acquisition: FAR-TECH has expertise in developing the “smarts” that enable hardware sub-systems to function as an integrated turn-key system. This is developed using tools such as LabVIEW, custom C++ code, and PLC programming.
