Abstract
A radio frequency DC coupling drive circuit for a multi-path segmented ion well comprises a radio frequency input part (1), a DC coupling input part (2), a filtering part (3) and a synthetic waveform output part (4), wherein the filtering part (3) is composed of an inductor L1 and a capacitor C1. The working principle is that a radio frequency high-voltage signal transmits a high-frequency AC signal through the radio frequency input part (1), a DC voltage signal transmits a signal through the DC coupling input part (2), and the two signals with different waveforms are overlapped through the synthetic waveform output part (4) to obtain a synthetic voltage signal. The filtering part (3) which is composed of the inductor L1 and the capacitor C1 forms a filtering circuit to prevent the high-voltage radio frequency signal of the radio frequency input part (1) from being fed back to the DC coupling input part (2) to damage a DC input power source. The radio frequency DC coupling drive circuit for the multi-path segmented ion well can be widely used for study of transmission and storage of the ion well.
