High-Performance Diamond: A Key Material for Detector Applications in Extreme Environments

From the intense radiation fields at the core of nuclear reactors to cosmic ray bursts in deep space exploration, these extreme environments feature high temperatures, high pressures, intense radiation, and strong corrosion, imposing extremely stringent requirements on detection technology. Traditional detector materials often fail in such extreme conditions due to sudden performance degradation or structural damage. In contrast, diamond has become a critical material for survival and operation in extreme environments thanks to its unparalleled properties, including ultra-high hardness, extremely high thermal conductivity, excellent thermal stability, and outstanding radiation resistance.

Core Application Scenarios

Nuclear Energy Sector

Diamond serves as a core material for detector devices in nuclear reactor operation, nuclear waste disposal, and fusion experiments due to its radiation resistance and high-temperature tolerance. For instance, electronic-grade single-crystal diamond features a wide bandgap, enabling low dark current and high sensitivity, making it an ideal material for detection chips to achieve real-time data monitoring. In fusion experiments, diamond thin films are used as laser windows or energy output windows to withstand the extreme heat flux and neutron radiation of plasma.

Deep Space Exploration Sector

For diamond radiation detectors, internal electronic devices must operate stably under extreme temperature gradients and radiation fields. Boron-doped single-crystal diamond offers excellent corrosion resistance and high chemical stability, providing a superior foundation for electrode materials and power electronic devices, thereby enhancing device operational reliability and extending service life.
