Helium-3 molecule

Helium-3, an essential molecule

One of the rarest gasses, helium-3 is stable, inert, nontoxic and nonflammable. Helium-3 has a wide range of applications. It is an essential molecule for neutron detection, dilution refrigerators, ultra low temperature physics research and aneutronic fusion.

3He is a light and non radioactive isotope of helium, obtained from the transformation of tritium. At a glance:

  • Isotopic purity level of 99.8%
  • Chemical purity level of 99.99%

 

A key component of dilution refrigerators

Dilution refrigerators are used by scientists to perform different kinds of experiments such as dark matter research. 3He is used as a cooling power, within the dilution refrigerator, to reach near-absolute-zero temperatures which reduces noise or interference in calculations.

 

 

3He and Quantum Computing

With unique properties, like a boiling temperature of 3.19K (- 270° Celsius), helium-3 allows to reach temperatures close to absolute zero that are necessary in quantum computers, allowing them to process exponentially more data compared to classical computers. The promise of quantum computing is accelerated development in many fields including the search for new drugs, the discovery of new materials, and even cyber defense.

Quantum Computing

 

Neutron Detection

Neutron detection commonly uses helium-3 as a reactive agent. Neutron detection is used by research in particle physics and science of materials. The most famous use of neutron detection is in security gates to detect radioactive materials and ensure border security.

 

Aneutronic Fusion

Aneutronic fusion is still at an experimental stage but is meant to be the next generation of power supply, promising to deliver an energy that should be less costly with no long-term nuclear waste. In this process driven by aneutronic reaction schemes, 3He is used as a fuel.
