Superconducting Electron Linacs

 
At Niowave, Inc., superconducting electron linear accelerators (linacs) are being built to tackle America’s high-tech challenges in fields as diverse as health care and national security. Niowave is aggressively pursuing commercial markets for compact versions of superconducting electron linacs:

  • Medical Radioisotopes (without the need for a nuclear reactor or highly enriched uranium)
  • Free Electron Lasers (high power tunable lasers at wavelengths not available today)
  • X-ray Sources (active interrogation, food irradiation and medical equipment sterilization)
  • Neutron Sources (high-intesity fast and thermal neutron flux without a nuclear reactor)

Over the past 30 years, the Department of Energy has developed superconducting particle accelerators for the largest and most powerful atom smashers ever built. These huge machines accelerate electrons and atoms to nearly the speed of light to understand the makeup of matter and how the universe works. That quest continues on many machines around the world today, with each of these machines costing roughly a billion dollars each. Much like Space-X has adapted NASA technology for commercial space applications, Niowave has adapted this technology for use in compact, cost efficient accelerators for a number of commercial applications.

In the simplest terms, superconductivity is used to efficiently accelerate electrons to high velocity and energy. The kinetic energy of the electrons is then used as a tool for a number of purposes. Niowave has pioneered the development of complete turn-key superconducting electron linacs that operate at 4 Kelvin for a broad range of commercial applications. In addition to the niobium accelerating structure (see Figure 1), the complete system includes the liquid helium refrigerator, high power microwave source, radiation shielding and licensing from the Nuclear Regulatory Commission. A conceptual layout of the complete system is shown in Figure 2. This integrated system enables a company or university research group to quickly and inexpensively use the electron beam for their research or industrial process. Key applications and the associated parameters for the superconducting linac are summarized in Table 1.
