In this paper, using the TM010 mode of the cavity BPM to measure the beam charge will be introduced. The data processing methods including harmonic analysis, time domain analysis and principle component analysis (PCA) are used and compared in evaluating the resolution of the beam charge. On the basis of this, the results of the evaluation at a ultra-low charge are also given and indicates the superiority of the cavity probe in the measurement of lower beam charge. In addition, the use of double-cavity mixing method to measure the beam charge will be proposed as well.
