Abstract :
In KEKB low energy positron ring (LER), the density of the electron cloud near the beam is estimated by separating a high energy component of the electron current monitored at a pump port of a vacuum chamber. The estimated density is consistent with simulations. Further investigation is necessary to understand the obtained data.
