China is building a new neutrino detector named TRIDENT, the Tropical Deep-sea Neutrino Telescope. They’re building it in the South China Sea, near the equator. This next-generation neutrino …
Figure 2 shows the horizontal coverage of neutrino telescopes at Lake Baikal, the South China Sea, and the South Pole.The horizontal direction is the ideal window of high-energy neutrinos above 100 TeV, where the neutrinos are not affected by the Earth’s absorption and the atmospheric muons are mostly obscured.
Instructions:
- HUNT is expected to provide a valuable research platform for marine science.
- HUNT aims to detect galactic and extragalactic high-energy neutrino sources in a short period.
- Detecting high-energy neutrinos is extremely challenging due to their characteristics.
- Current international experiments are limited by detection technology and financial investment, with effective detector volumes between 1 and 8 cubic km.
- The South China Sea is China’s only viable site for the telescope due to its vast expanse.
- The deployment of the detectors was assisted by China’s first deep-sea multi-functional scientific research vessel, Tansuo 3, and the Shenhai Yongshi, a 4,500-meter-class manned submersible.
- The detector prototypes were jointly developed by the Ocean University of China,IHEP,and the Institute of Acoustics under the Chinese Academy of Sciences.
- The deployed detectors have been successfully connected to the South China Sea Seabed Scientific Observation Network, another major national scientific infrastructure project lead by the Institute of acoustics.

Interview with Dr. Li Wei, Neutrino physicist and Project Specialist
We sat down with Dr. Li Wei, a renowned neutrino physicist and specialist in the HUNT project, to discuss the significance of this endeavor and its potential impact on marine science and astrophysics.
On the Launch of the HUNT Detector Prototype
Editor: Can you tell us about the recent launch of the HUNT detector prototype into the South China Sea?
Dr. Li Wei: Yes, we recently launched the HUNT detector prototype into the South China Sea. The deployment was a collaborative effort involving the scientific research ship Tansuo-3 and the manned submersible Shenhai Yongshi. This prototype is a significant step towards establishing a comprehensive research platform for marine science and high-energy neutrino detection.
Challenges in High-Energy Neutrino Detection
Editor: High-energy neutrino detection is notoriously challenging. What are some of the key challenges faced in this field?
Dr. li Wei: Detecting high-energy neutrinos is indeed extremely challenging due to their elusive nature. Neutrinos rarely interact with matter, making them difficult to detect. Additionally, the vast volumes of water required for effective detection are technically demanding and costly. Current international experiments are limited by detection technology and financial investment, with effective detector volumes typically ranging between 1 and 8 cubic kilometers.
The South China Sea as a Viable Site
Editor: Why was the South China Sea chosen as the site for the HUNT telescope?
Dr. Li Wei: The South China Sea is China’s only viable site for this type of telescope due to its vast expanse. Its geographical and environmental characteristics make it an ideal location for deploying and maintaining such a large-scale detector. Additionally, the equatorial location offers unique advantages for detecting high-energy neutrinos from various cosmic sources.
Collaborative Efforts and Technological Advancements
Editor: Can you elaborate on the collaborative efforts and technological advancements involved in this project?
Dr. Li Wei: The detector prototypes were jointly developed by the Ocean University of China, IHEP, and the Institute of Acoustics under the Chinese Academy of Sciences. The deployment was assisted by China’s first deep-sea multi-functional scientific research vessel, Tansuo 3, and the 4,500-meter-class manned submersible Shenhai Yongshi. These technological advancements have been crucial in overcoming the challenges associated with deep-sea operations.
Integration with the South China Sea Seabed Scientific Observation Network
Editor: How has the integration with the South China Sea Seabed Scientific Observation Network enhanced this project?
Dr. Li Wei: The deployed detectors have been successfully connected to the South China Sea Seabed Scientific Observation Network, another major national scientific infrastructure project led by the Institute of Acoustics. This integration provides a comprehensive and interconnected system for marine scientific research, allowing for more accurate and extensive data collection.
Future Prospects and Research Goals
Editor: What are the future prospects and research goals for the HUNT project?
Dr. Li Wei: HUNT aims to detect galactic and extragalactic high-energy neutrino sources within a short period. This will provide valuable insights into the origins and behaviors of these elusive particles. Additionally, HUNT is expected to contribute considerably to marine science, offering a unique platform for studying deep-sea ecosystems and environmental changes.
Conclusion
The launch of the HUNT detector prototype into the south china Sea marks a significant milestone in the field of high-energy neutrino detection and marine science.
