Proxima Fusion’s proprietary design leverages advanced computational modeling and innovative engineering to achieve these goals, making it a leading contender in the fusion energy race.

Proxima Fusion’s Stellarator Approach: Proxima Fusion Raises 21m To Build On Its Stellarator Approach To Nuclear Fusion

Proxima Fusion is a company dedicated to developing a new generation of fusion power plants based on the Stellarator concept. This approach to fusion energy differs significantly from the more well-known Tokamak design, offering unique advantages and presenting its own set of challenges.

Key Differences Between Stellarators and Tokamaks

The Stellarator and Tokamak designs both aim to achieve controlled fusion reactions by confining a superheated plasma using magnetic fields. However, they differ in their approaches to generating and shaping these magnetic fields.

• Magnetic Field Generation: Tokamaks use a combination of toroidal (doughnut-shaped) and poloidal (circular) magnetic fields generated by external coils and a powerful electric current flowing through the plasma itself. Stellarators, on the other hand, rely solely on external coils to generate complex, three-dimensional magnetic fields that confine the plasma.
• Plasma Confinement: The complex magnetic field configuration in Stellarators allows for a more stable and predictable confinement of the plasma compared to Tokamaks, which can experience instabilities due to the plasma current.
• Steady-State Operation: Stellarators are designed to operate in a steady-state mode, meaning the fusion reaction can be sustained continuously without the need for periodic interruptions as required in Tokamaks for recharging the plasma current.

Overcoming Challenges with Traditional Stellarator Designs, Proxima fusion raises 21m to build on its stellarator approach to nuclear fusion

While Stellarators offer several advantages, they also face challenges that have hindered their widespread adoption. Traditional Stellarator designs often suffer from:

• Complex Coil Geometry: The intricate magnetic field configuration requires a large number of precisely shaped and positioned coils, making them expensive and difficult to construct.
• Plasma Performance: The complex magnetic field can lead to regions of low magnetic field strength, potentially allowing plasma to escape and reducing efficiency.

Proxima Fusion’s Stellarator design aims to address these challenges by:

• Simplified Coil Design: Proxima Fusion employs a novel approach to coil design that significantly reduces the number of coils required while maintaining the necessary magnetic field complexity.
• Improved Plasma Confinement: Their design incorporates advanced techniques to optimize the magnetic field configuration, leading to improved plasma confinement and higher fusion power output.

Advantages of the Stellarator Approach

The Stellarator approach offers several potential advantages for achieving sustainable fusion energy:

• Steady-State Operation: The ability to operate continuously without interruptions could significantly improve the efficiency and economics of fusion power plants.
• Enhanced Plasma Stability: The more stable confinement of the plasma in Stellarators could lead to higher energy gain and potentially reduce the need for complex plasma control systems.
• Reduced Maintenance: The absence of a plasma current eliminates the need for frequent maintenance associated with Tokamak designs.

Advanced Stellarator Design

Proxima Fusion’s stellarator design is a unique and innovative approach to magnetic confinement fusion. It utilizes a complex arrangement of magnetic coils to create a toroidal (doughnut-shaped) magnetic field that confines the hot plasma. This design offers several advantages over traditional tokamaks, including:

• Enhanced Plasma Stability: Stellarators are inherently more stable than tokamaks, reducing the risk of disruptions that can damage the reactor and interrupt operation.
• Continuous Operation: Stellarators can operate continuously, unlike tokamaks which require periodic pulses. This continuous operation allows for more efficient energy production.
• Flexibility in Plasma Shape: Stellarators offer more flexibility in shaping the plasma, allowing for optimization of energy confinement and heating.

Proxima Fusion’s design further optimizes these advantages by incorporating:

Novel Heating and Current Drive Systems

Proxima Fusion is developing innovative heating and current drive systems to maintain the plasma at the required high temperatures and sustain the necessary plasma current for fusion reactions. These systems include:

• Electron Cyclotron Resonance Heating (ECRH): ECRH utilizes microwaves to heat the electrons in the plasma, increasing the plasma temperature and driving the fusion reaction.
• Neutral Beam Injection (NBI): NBI involves injecting high-energy neutral atoms into the plasma, transferring energy to the plasma ions and increasing the plasma temperature.

These heating systems are crucial for achieving the high temperatures needed for fusion, and Proxima Fusion’s innovative approaches are aimed at maximizing heating efficiency and minimizing energy loss.

Comparison with Other Fusion Companies

While Proxima Fusion focuses on stellarator technology, other fusion companies are pursuing different approaches, such as tokamaks, inertial confinement fusion, and other advanced concepts.

• Tokamak: Tokamaks, like ITER, are the most widely researched fusion approach.
