Description

technical field [0001] The invention belongs to the technical field of signal transmission cables, and in particular relates to a low-noise, high-shielding, high-temperature-resistant, radiation-resistant, fA-level current signal cable suitable for radiation environments and a manufacturing process. Background technique [0002] Weak signal measurement and control technology plays an increasingly important role in high-sensitivity sensors, high-gain amplifiers and other equipment. The cable used as a connecting device will generate weak signals during use, which will form system noise, and the noise will cause the graph or spectrum of the weak signal to change, which will cause the weak signal to be undetectable, inaccurate, or generate an error signal. Reducing noise or reducing the impact of environmental factors on cables will undoubtedly improve the accuracy of measurement and control technology. With the development of radiation detection components to smaller and more...
