Ny 30KA højstrømssensor kan måle ultrastor strøm

Recently, an exciting piece of news has swept the scientific and technological community and even the world – the Experimental Superconducting Tokamak (EAST), known as the “artificial sun”, has successfully set a new world record in Hefei, Anhui, achieving “high-quality combustion” for 1,000 seconds at 100 million degrees Celsius for the first time. This milestone achievement not only marks a major breakthrough in China’s fusion energy research, but also opens up a new path for all mankind to explore a clean and sustainable energy future.

EAST, a scientific research device shaped like a “giant tank”, is not only a carrier of scientists’ dreams and hopes, but also a culmination of cutting-edge technology. It combines a series of extreme technical challenges such as “ultra-high temperature”, “ultra-low temperature”, “ultra-high vacuum”, “ultra-strong magnetic field” and “ultra-large current”, each of which is an extreme test of scientific research capabilities. Among these challenges, the measurement of “ultra-large current” is particularly critical, which is directly related to the stability and efficiency of fusion reactions.
