Joe Finberg

Joseph Finberg, the visionary founder of F Squared Fusion, holds a degree in Physics from Columbia University and has also studied at the University of Oxford. With a background steeped in cutting-edge physics and a passion for solving one of the world’s most pressing challenges, Joseph is dedicated to making fusion energy a commercial reality. His extensive research in plasma physics, particularly electromagnetic gyrokinetic turbulence in tokamaks, has positioned him as an expert in the field, driving F Squared Fusion’s innovative approach to energy generation.

Joseph’s research has in the past looked into electromagnetic (EM) gyrokinetic (GK) turbulence in tokamaks and the interactions between energetic particles and plasma turbulence. Unlike well-understood electrostatic turbulence, EM GK turbulence and its impact on energy, particle, and momentum transport are less understood and poorly parameterised. The transition from electrostatic to electromagnetic regimes above a specific beta threshold can lead to significant enhancement of transport and unbounded heat flux growth, critical for advanced fusion reactors. Joseph has also researched how energetic alpha particles from Deuterium-Tritium fusion, crucial for achieving a self-heating, burning plasma, interact with plasma turbulence and destabilise Alfven waves, affecting confinement and power balance. Furthermore, he plans to explore pulsed fusion using direct energy capture from deuterium-Helium 3 fusion, aiming to reduce neutron production and radiation damage, leveraging intense energy bursts to optimise conversion and minimise reactor wear for sustainable fusion energy generation.

In his spare time he enjoys fountain pens, chess, poker, sailing and travel.

Powering a Sustainable Future

Our Approach

Plasma Stability

Ensuring the stability of plasma is crucial for maintaining the conditions necessary for fusion. While we are currently in prototyping stage, we plan to utilize advanced control systems and diagnostics to monitor and stabilize plasma, preventing disruptions and maximizing efficiency.

Plasma Confinement

Effective confinement of plasma is critical to sustaining the extreme temperatures and pressures required for fusion. We plan to implement cutting-edge magnetic confinement techniques, such as tokamaks and stellarators, to create powerful magnetic fields that contain and control the plasma. These magnetic fields prevent the plasma from coming into contact with the reactor walls, reducing energy losses and maintaining the necessary conditions for fusion. Our innovative confinement methods enhance the overall performance and viability of our fusion reactors.

Induction

Our induction technology focuses on initiating and maintaining the fusion reaction. By using precisely controlled electric currents, we can induce the necessary conditions for fusion to occur, ensuring a steady and reliable energy output.

Energy Storage

Storing the energy produced by fusion reactions is critical for practical use. We are developing advanced energy storage solutions that can capture and distribute the power generated, ensuring a stable and continuous energy supply.
