About CPAC

Compact Particle Acceleration Corporation (CPAC) is a spinout of TomoTherapy Incorporated (NASDAQ: TOMO). It is developing and commercializing a highly compact intensity-modulated proton therapy (IMPT) system powered by the dielectric-wall accelerator (DWA), a revolutionary proton accelerator that has a substantially smaller structure and greater flexibility than other proton therapy systems.

The breakthrough in size and power is made possible by three key inventions:
  • High-gradient insulators that allow for substantial increases in voltage-holding capacity
  • Dielectric materials that are embedded with nanoparticles to facilitate the transmission and isolation of extremely high voltages;
  • Optical switches that can control high-power loads at ultra high-speeds in a very compact size

We believe that these enabling platform technologies that combine extreme switching speed and power handling capability will allow us to create a proton therapy system that will dominate the radiotherapy industry.

CPAC has teamed up with TomoTherapy to leverage its medical systems design expertise and significant channel presence. This partnership will allow CPAC to concentrate on its core development expertise while working with an established partner on the critical tasks of systems integration, sales, marketing, and service.

CPAC also works with other key development partners, such as Lawrence Livermore National Laboratory (LLNL), to continue to further its technology and to investigate new applications.
