👉 Rheotron is a type of device used in radio astronomy to amplify or enhance signals. It works by using a superconducting coil that oscillates at high frequencies, which allows for higher amplitude and lower noise levels than traditional radio antennas. This technology is particularly useful when dealing with very low power signals, as it can be used to amplify small amounts of light or other electromagnetic radiation without the need for large amplifiers. The term "rheotron" comes from the Greek word "rhē
