abstract = {{At the SuperKEKB injector linac, positrons are generated by striking electron beam at tungsten target. The secondary electrons are also produced during positron creation and accelerated in the positron capture section. A new wideband feedthrough-beam position monitor (BPM) system was developed for synchronous detection of secondary produced e⁻ and e⁺ beams with temporal separation of about 180 ps. When e⁺/e⁻ bunches pass through the accelerating structure or vacuum duct of different radius, they generate wakefields. These wakefields can be directly observed with the feedthrough-BPM. A simulation study has also been carried to validate the observed wakefield effects with the feedthrough-BPM. The effects of wakefields on beam parameters will be reported in this paper.}},
