The working principle of tungsten rhenium probe needle is based on the energy level structure and electron transition mechanism of W-Re alloy. When high-energy particles or rays interact with tungsten-rhenium alloy, electron transition and energy transfer will occur, causing ionization or excitation effects. These effects will cause changes in electron density, which in turn will generate current signals. By measuring the size and changes of the current signal, information such as the energy and flow of the particles can be inferred.
