Our cryogenic sensors enable in-situ measurements, from room temperature to near absolute zero, in some of the largest magnetic fields on the planet.
Improving cryogenic systems with graphene sensors
Our graphene based magnetic field sensors are the first and only Hall effect sensors capable of measuring high magnetic fields at cryogenic temperatures. Particle accelerators, fusion reactors, and MRI systems are all benefiting from them today.
Why use Graphene?
• Ultra-low temperature operation (down to <10mK)
• Exceptional stability up to 30T
• Superior accuracy with μT sensitivity
Paragraf is enabling the next wave of world-changing technologies to become a reality, enhancing magnetic sensing and measurements in these systems.
Applications
Quantum computing
Paragraf graphene-based cryogenic sensors play a crucial role in quantum computing by enabling the precise measurement and control of quantum systems at extremely low temperatures. Use cases include:
- Magnetic Field Measurement. Superconducting qubits are extremely sensitive to magnetic fields. Paragraf sensors provide valuable feedback for magnetic field cancellation or shielding to minimize unwanted interference.
- Performance characterization. Cryogenic sensors are used to characterize the performance of individual qubits or the entire quantum system. These measurements help assess the quality and reliability of the qubits and guide the development of more robust quantum computing architectures.
Magnet calibration
An increasingly significant limitation of conventional Hall sensors is their inability to be used at cryogenic temperatures due to the electronic components involved not functioning at these extremes and the changes in adhesion (because of thermal mismatch) between multiple material interfaces causing thermal drift. Paragraf’s graphene-based cryogenic sensors are the only Hall sensors to offer accurate, repeatable performance at cryogenic temperatures.
Applications include:
- Magnet R&D and manufacture
- In-situ magnetic field monitoring and field magnitude and vector verification during cryogenic experiments
- Magnetic shielding attenuation factor determination – use the same sensor for field measurement on the inside and outside of the shield
