An arbitrary Rogowski coil expression was deduced in this paper. Using high permeability magnetic core and adding turns of the coil, the Rogowski coil was designed, which could measure the low current with slow-rising edge. And the electron-beam signal was obtained by the Rogowski coil. Using the deduced expression of arbitrary Rogowski coil, the current waveforms with low frequency and high frequency were gained. The results show that beam oscillation exists in this electron-beam plasma system, and the oscillation amplitude reaches 12%.
