17:11 - Vadim Sajaev opened the RT feedback loops between the SR topup shots, collected SR data for ~20 seconds, and closed RT feedback loops. There was a brief spike in storage ring RMS beam motion during the time when the feedback loops were open. The experiment was done as a part of investigation into 100Hz RMS beam motion in the vertical plane measured and reported by the user at 4-ID.
