MD 754: Instability Threshold for Train with 25ns Spacing

Measurements made since the beginning of run II at 6.5 TeV have shown that there is a large discrepancy in the instability thresholds between single bunches and trains of 72 bunches with 25ns spacing, whereas the same result is expect for pure impedance-induced instabilities. One possible explanatio...

description Measurements made since the beginning of run II at 6.5 TeV have shown that there is a large discrepancy in the instability thresholds between single bunches and trains of 72 bunches with 25ns spacing, whereas the same result is expect for pure impedance-induced instabilities. One possible explanation is that the presence of electron cloud is affecting the beam stability. This MD will attempt to determine if electron cloud is the dominant mechanism affecting beam stability.
