TAE Technologies, formerly Tri Alpha Energy, is an American company based in Foothill Ranch, California, created for the development of aneutronic fusion power. The company's design relies on a field-reversed configuration (FRC), which combines features from other fusion concepts in a unique fashion.[6] It aims to manufacture a prototype commercial fusion reactor by 2030.[7]

The company was founded in 1998, and is backed by private capital.[8][9][10][11] They operated as a stealth company for many years, refraining from launching its website until 2015.[12] The company did not generally discuss progress nor any schedule for commercial production.[10][13][14] However, it has registered and renewed various patents.[15][16][17][18][19][20][21] It regularly publishes theoretical and experimental results in academic journals with over 150 publications and posters at scientific conferences over the last five years. TAE has a research library hosting these articles on their website.[22][23][24]

Organization[]

As of 2014, TAE Technologies reportedly had more than 150 employees and had raised over $150 million,[25] far more than any other private fusion power research company or the vast majority of federally-funded government laboratory and university fusion programs.[26] Main financing has come from Goldman Sachs and venture capitalists such as Microsoft co-founder Paul Allen's Vulcan Inc., Rockefeller's Venrock, and Richard Kramlich's New Enterprise Associates. The Government of Russia, through the joint-stock company Rusnano, invested in Tri Alpha Energy in October 2012, and Anatoly Chubais, Rusnano CEO, became a board member.[10][13][27][28][29] Other investors include the Wellcome Trust and the Kuwait Investment Authority.[30]

Since 2014 TAE Technologies has worked with Google to develop a process to analyze the data collected on plasma behavior in fusion reactors.[31] In 2017, using a machine learning tool developed through the partnership and based on the "Optometrist Algorithm", TAE was able to find significant improvements in plasma containment and stability over the previous C-2U machine.[32] The results of the study were published in Scientific Reports.[33] Ernest Moniz, the former United States Secretary of Energy at the US Department of Energy, joined the company's board of directors in May 2017.[34][35] As of July 2017 the company reported that it had raised more than $500 million in backing.[6] In November 2017 the company was admitted to a United States Department of Energy Innovative and Novel Computational Impact on Theory and Experiment program that allowed the company access to the Cray XC40 supercomputer.[1] As of 2020, the company had raised over $600 million,[36] and as of 2021, around $880 million.[30]

Steven Specker stepped down as CEO in July 2018. Michl Binderbauer moved from CTO to CEO following Specker's retirement. Specker will remain as a board member and advisor.[37]

TAE Life Sciences[]

In March 2018 TAE Technologies announced that it had raised $40 million to spin off a subsidiary focused on refining boron neutron capture therapy (BNCT) for cancer treatment.[38] The subsidiary is named TAE Life Sciences and it received funding led by ARTIS Ventures.[39] TAE Life Sciences also announced that it would partner with Neuboron Medtech, which will be the first to install the company's beam system. The company shares common board members with TAE Technologies and is led by Bruce Bauer.[40]

Design[]

Underlying theory[]

In mainline fusion approaches, the energy needed to allow reactions, the Coulomb barrier, is provided by heating the fusion fuel to millions of degrees. In such fuel, the electrons disassociate from their ions, to form a gas-like mixture known as a plasma. In any gas-like mixture, the particles will be found in a wide variety of energies, according to the Maxwell–Boltzmann distribution. In these systems, fusion occurs when two of the higher-energy particles in the mix randomly collide. Keeping the fuel together long enough for this to occur is a major challenge.

TAE's design is ultimately based on another approach, colliding beam fusion, or CBF. In CBF the fuel is not in the form of a plasma but instead consists of a stream of individual particles from a particle accelerator. In this approach, every ion has the energy needed to undergo fusion. In most designs, two such beams are created and aimed at each other, with the fusion taking place at the collision point. Unfortunately, it is very easy to demonstrate that the number of fusion events that take place in such systems is far less than the number of times the particles simply bounce off each other, or scatter. Even though those reactions that do occur are very powerful, they cannot make up for the losses from those particles that scatter.

To make such a system work, those particles that scatter away must be collected somehow so they can undergo additional chances of having a collision, thousands of times at a minimum. Several approaches have been suggested, most notably the migma concept of the 1970s. Migma used a unique magnetic arrangement that naturally led the particles to orbit a storage tank so they constantly passed through the middle. However, it was shown that the maximum allowable density in any practical device was too low to be useful.

TAE's design[]

See also: Compact toroid

TAE's design is ultimately a CBF, but differs in the way it keeps the injected particles stored. Instead of a magnetic tank, the TAE design forms a field-reversed configuration (FRC), a self-stabilized rotating toroid of particles similar to a smoke ring. In the TAE system, the ring is made as thin as possible, about the same aspect ratio as an opened tin can. Particle accelerators inject fuel ions tangentially to the surface of the cylinder, where they either react or are captured into the ring as additional fuel.

Unlike other magnetic confinement fusion devices such as the tokamak, FRCs provide a magnetic field topology whereby the axial field inside the reactor is reversed by eddy currents in the plasma, as compared to the ambient magnetic field externally applied by solenoids. The FRC is less prone to magnetohydrodynamic and plasma instabilities than are other magnetic confinement fusion methods.[41][42][43] The science behind the colliding beam fusion reactor is used in the company's C-2, C-2U and C-2W projects.

A key concept in the TAE system is that the FRC is kept in a useful state over an extended period. To do this, the accelerators inject the fuel such that when the particles scatter within the ring they cause the fuel already there to speed up in rotation. This process would normally slowly increase the positive charge of the fuel mass, so electrons are also injected to keep the charge roughly neutralized.

The FRC is held in a cylindrical, truck-sized vacuum chamber containing solenoids.[11][44][45][46] It appears the FRC will then be compressed, either using adiabatic compression similar to those proposed for magnetic mirror systems in the 1950s, or by forcing two such FRCs together using a similar arrangement.[24]

The design must achieve the "hot enough/long enough" (HELE) threshold to achieve fusion. The required temperature is 3 billion degrees Celsius (~250 keV), while the required duration (achieved with C2-U) is multiple milliseconds.[47]

The 11B(p,α)αα aneutronic reaction[]

Main article: Aneutronic fusion

An essential component of the design is the use of "advanced fuels", i.e. fuels with primary reactions that do not produce neutrons, such as hydrogen and boron-11. FRC fusion products are all charged particles for which highly efficient direct energy conversion is feasible. Neutron flux and associated on-site radioactivity is virtually non-existent. So unlike other nuclear fusion research involving deuterium and tritium, and unlike nuclear fission, no radioactive waste is created.[48] The hydrogen and boron-11 fuel used in this type of reaction is also much more abundant.[49]

TAE Technologies relies on the clean 11B(p,α)αα reaction, also written 11B(p,3α), which produces three helium nuclei called α−particles (hence the name of the company) as follows:

1p + 11B → 12C
12C → 4He + 8Be
8Be → 2 4He

A proton (identical to the most common hydrogen nucleus) striking boron-11 creates a resonance in carbon-12, which decays by emitting one high-energy primary α−particle. This leads to the first excited state of beryllium-8, which decays into two low-energy secondary α-particles. This is the model commonly accepted in the scientific community since the published results account for a 1987 experiment.[50]

TAE claimed that the reaction products should release more energy than what is commonly envisaged. In 2010, Henry R. Weller and his team from the Triangle Universities Nuclear Laboratory (TUNL) used the high intensity γ-ray source (HIγS) at Duke University, funded by TAE and the U.S. Department of Energy,[51] to show that the mechanism first proposed by Ernest Rutherford and Mark Oliphant in 1933,[52] then Philip Dee and C. W. Gilbert from the Cavendish Laboratory in 1936,[53] and the results of an experiment conducted by French researchers from IN2P3 in 1969,[54] was correct. The model and the experiment predicted two high energy α-particles of almost equal energy. One was the primary α-particle and the other a secondary α-particle, both emitted at an angle of 155 degrees. A third secondary α-particle is also emitted, of lower energy.[55][56][23][57]

Inverse cyclotron converter (ICC)[]

See also: Direct energy conversion

Direct energy conversion systems for other fusion power generators, involving collector plates and "Venetian blinds" or a long linear microwave cavity filled with a 10-Tesla magnetic field and rectennas, are not suitable for fusion with ion energies above 1 MeV. The company employed a much shorter device, an inverse cyclotron converter (ICC) that operated at 5 MHz and required a magnetic field of only 0.6 tesla. The linear motion of fusion product ions is converted to circular motion by a magnetic cusp. Energy is collected from the charged particles as they spiral past quadrupole electrodes. More classical collectors collect particles with energy less than 1 MeV.[11][16][17]

The estimation of the ratio of fusion power to radiation loss for a 100 MW FRC has been calculated for different fuels, assuming a converter efficiency of 90% for α-particles,[58] 40% for Bremsstrahlung radiation through photoelectric effect, and 70% for the accelerators, with 10T superconducting magnetic coils:[11]

  • Q = 35 for deuterium and tritium
  • Q = 3 for deuterium and helium-3
  • Q = 2.7 for hydrogen and boron-11
  • Q = 4.3 for polarized hydrogen and boron-11.

The spin polarization enhances the fusion cross section by a factor of 1.6 for 11B.[59] A further increase in Q should result from the nuclear quadrupole moment of 11B.[43] And another increase in Q may also result from the mechanism allowing the production of a secondary high-energy α-particle.[23][56][57]

TAE Technologies plans to use the p-11B reaction in their commercial FRC for safety reasons and because the energy conversion systems are simpler and smaller: since no neutron is released, thermal conversion is unnecessary, hence no heat exchanger or steam turbine.

The "truck-sized" 100 MW reactors designed in TAE presentations are based on these calculations.[11]

Projects[]

CBFR-SPS[]

The CBFR-SPS is a 100 MW-class, magnetic field-reversed configuration, aneutronic fusion rocket concept. The reactor is fueled by an energetic-ion mixture of hydrogen and boron (p-11B). Fusion products are helium ions (α-particles) expelled axially out of the system. α-particles flowing in one direction are decelerated and their energy directly converted to power the system; and particles expelled in the opposite direction provide thrust. Since the fusion products are charged particles and does not release neutrons, the system does not require the use of a massive radiation shield.[60][61]

C-2[]

Various experiments have been conducted by TAE Technologies on the world's largest compact toroid device called "C-2". Results began to be regularly published in 2010, with papers including 60 authors.[24][62][63][64][65] C-2 results showed peak ion temperatures of 400 Electron volts (5 million degrees Celsius), electron temperatures of 150 Electron volts, plasma densities of 1E19 m−3 and 1E9 fusion neutrons per second for 3 milliseconds.[24][66]

Russian cooperation[]

The Budker Institute of Nuclear Physics, Novosibirsk, built a powerful plasma injector, shipped in late 2013 to the company's research facility. The device produces a neutral beam in the range of 5 to 20 MW, and injects energy inside the reactor to transfer it to the fusion plasma.[21][67][68]

C-2U[]

In March 2015, the upgraded C-2U with edge-biasing beams showed a 10-fold improvement in lifetime, with FRCs heated to 10 million degrees Celsius and lasting 5 milliseconds with no sign of decay.[citation needed] The C-2U functions by firing two donut shaped plasmas at each other at 1 million kilometers per hour,[69] the result is a cigar-shaped FRC as much as 3 meters long and 40 centimeters across.[70] The plasma was controlled with magnetic fields generated by electrodes and magnets at each end of the tube. The upgraded particle beam system provided 10 megawatts of power.[71][72]

C-2W/Norman[]

In 2017, TAE Technologies renamed the C-2W reactor "Norman" in honor of the company's co-founder Norman Rostoker who died in 2014. In July 2017, the company announced that the Norman reactor had achieved plasma.[73] The Norman reactor is reportedly able to operate at temperatures between 50 million and 70 million°C.[6] In February 2018, the company announced that after 4,000 experiments it had reached a high temperature of nearly 20 million°C.[74] In 2018, TAE Technologies partnered with the Applied Science team at Google to develop the technology inside Norman to maximize electron temperature, aiming to demonstrate breakeven fusion.[75] In 2021, TAE Technologies stated Norman was regularly producing a stable plasma at temperatures over 50 million degrees, meeting a key milestone for the machine and unlocking an additional $280 million in financing, bringing its total of funding raised up to $880 million.[30]

Copernicus[]

The Copernicus device involves deuterium–tritium fusion and is expected to attain net energy gain.[76][37] The approximate cost of the reactor is $200 million, and it is intended to reach temperatures of around 100 million°C. TAE intends to start construction in 2020 and begin test runs in 2023.[77]

Da Vinci[]

The Da Vinci device is a proposed successor device to Copernicus. It is a prototype commercially scalable fusion energy reactor designed to bridge between D-T and a p-11B fuel. Conditional on the success of Copernicus, it will be developed in the second half of the 2020s and will be designed to achieve a plasma of 3 billion°C, keep a proton-boron fuel stable and produce fusion energy.[77]
