Princeton Propeller is a series of talks supported by the Princeton Area Alumni Association (PA3) to showcase technical innovation. Our team was recently invited to give a talk on the new frontier of commercial fusion development! Dr. Swanson and Ms. Thomas took the podium on February 11, 2020, at the Quadrangle Club on Princeton’s campus.
We are now joined by over a dozen private companies in the UK and the US pursuing commercial fusion development. Recent programs in the Department of Energy and their ARPA-E advanced projects division have supported teams in magneto-inertial confinement (ALPHA), compact tokamaks, pinches, and our PFRC (OPEN), and public-private partnerships between labs and the private companies (INFUSE). It’s a great time to be in fusion research!
We have been hard at work on our ARPA-E project and just submitted our second quarterly report! Our team, including our summer interns, presented several posters on the latest PFRC-2 experimental results at the APS Division of Plasma Physics meeting, held Oct. 21-25 in Ft. Lauderdale, FL.

Princeton Fusion Systems has been awarded $1.25 Million from ARPA-E for Low-Radioactivity Compact Fusion Devices
Today ARPA-E announced announced that PFS has received a competitive $1.25 million award from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E), as part of the Energy cohort of OPEN 2018.
Princeton Fusion Systems seeks to develop technologies to enable future commercial fusion power. Our team’s concept is a small, clean, and portable design based on a field-reversed-configuration plasma. The concept uses an innovative method called odd-parity rotating magnetic field (RMF) to drive electrical current and heat the plasma to fusion temperatures. Under this award, the team will pursue improved electron and ion temperatures through RMF, as well as identify the modeling needed to elucidate the key heating and loss mechanisms for the fusion reactor concept. The team’s ultimate power plant design seeks a very small footprint for a compact, potentially transportable, distributed energy resource that is fully dispatchable and emissions-free.
PFS received this competitive award from ARPA-E’s OPEN 2018 program, in which teams develop innovative technologies to transform the nation’s energy system. OPEN solicitations are an open call to scientists and engineers for technologies across the entire scope of ARPA-E’s energy mission.
Princeton Fusion Systems is developing a new class of small fusion reactors. The terrestrial reactor is the PFRC, or Princeton Field-Reversed Configuration; configured as a fusion rocket it is known as Direct Fusion Drive (DFD).
