Abstract：
Considering the effect of photoelectron, BEPCⅡ′s beam position monitor (BPM) uses antechamber structure. The cut-off frequency of TE mode is maybe lower than the BPM signal processing frequency 500MHz. The power of TE mode will result in beam position measurement error. With monitoring the antechamber's TE mode power amplitude and calculating the transmission of TE mode power to BPM's electrodes, we can calculate the error of position measurement caused by TE mode. We found that the error is beyond the acceptance when the cut-off frequency of TE₁₀ mode is lower than 500MHz. By changing the slot length, the cut-off frequency is higher than 500MHz and the error could be accepted. At last the effect of the wakefield to the beam has been simulated and the longitudinal impedance of wakefield has been calculated.
