Enabling technologies for fusion power plants

A stellarator power plant depends on multiple complex systems functioning as one integrated whole.
Gauss Fusion is developing five critical technology areas that shape how a future plant could be designed, manufactured, assembled, operated and maintained. Each addresses a distinct challenge, while the GIGA™ platform provides the common system-level framework for their development and integration.

Gauss Fusion High Field Stellarator

Advanced high-field stellarator design

Building on Wendelstein 7-X experience for a power-plant-focused high-field stellarator.

Led by Dr. Samuel Lazerson, who brings experience directly from Wendelstein 7-X and Princeton Plasma Physics Laboratory.


Key features:

  • Provides the magnetic and engineering basis of the power-plant concept.
  • Considers magnets, heating, breeding and exhaust systems from the outset.
  • Balances plasma requirements with plant size and engineering constraints.
  • Supports system-level decisions across the wider GIGA™ platform.
  • Addresses the stellarator as a power plant, rather than as an isolated plasma device.
Gauss Fusion Demountable Mitechell Magnets

Demountable Mitchell Magnets (DMM™)

Fusion-magnet expertise applied to a demountable, maintainable high-field architecture.

Developed under Dr. Neil Mitchell, drawing on more than 30 years of fusion-magnet experience, including ITER.

Key features:

  • Uses modular magnet sections that can be manufactured separately.
  • Supports transport and assembly around the vacuum vessel.
  • Allows sections of the magnet system to be opened and reconnected.
  • Creates potential access routes for inspection and component replacement.
  • Addresses manufacture, assembly and maintainability as connected design requirements.
Gauss Fusion Tritium Breeding Blanket

HEXA™ Tritium Breeding

Building on helium-cooled pebble bed (HCPB) breeding-blanket research to create a modular architecture designed for industrial manufacture and maintenance.

Led by Jacobo Zegri, drawing on fusion and nuclear engineering experience including Fusion for Energy.

Key features:

  • Designed to capture neutrons produced by fusion reactions and support the production of tritium within the power plant.
  • Combines tritium breeding with heat extraction and shielding requirements.
  • Uses a modular structure intended to accommodate the geometry of the reactor.
  • Developed with manufacture, adaptation and maintenance considered within the wider plant design.
Gauss Fusion PinkCap Divertor Technology

PinkCap™ divertor

Leveraging edge plasma winds for improved pumping in fusion devices.

Led by Matteo Moscheni, an expert in edge plasma simulation and divertor physics

Key features:

  • Directs heat and particle exhaust away from the plasma.
  • Helps protect surrounding power-plant components.
  • Addresses conditions that affect stable operation and component lifetime.
  • Considers maintainability alongside plasma-exhaust performance.
  • Is developed in the context of the wider stellarator configuration and plant architecture.


Gauss Fusion Tritium

Tritium Fuel Cycle

Fuel-cycle development informed by practical experience of tritium operations.

Led by Dr. Paul Staniec, whose experience includes leading JET DTE2/3 tritium operations.

Key features:

  • Connects tritium breeding with the systems required to extract, process and return tritium to the plasma.
  • Provides the wider fuel-cycle architecture through which tritium must be managed across the plant.
  • Is being developed alongside Gauss Fusion’s tritium-breeding and materials technologies within the wider TRIMAT™ platform.
  • Is considered as part of the integrated GIGA™ power-plant system rather than as an isolated subsystem.
