1 e-cloud xbsm study data quicklook plots -- JWF On shift: MJF, MGB, KGS, JWF Notes: Gev, 30 bunches, 14 ns spacing, Big D optics (beta_y = ~20 m at xbsm source bend) CA, FZP and GAP (Hevimet slit) data taken, 4096 turns each. GAP analysis based on treating GAP as 16 um pinhole, fitting to templates (like CA or FZP). Results are very preliminary No cuts applied yet bad events (bad fits, off det. at large dipole amplitude, etc.) are included. Calibration file: 3C-5-dpp-ByHand calib Pedestal run: 5395 Data taken: Low, Medium and High Emittance (0.5, 0.75, 1.0 ma/bunch) = 20 pm-r (est.) Medium Emittance = 52 pm-r (est.) High Emittance = 308 pm-r (est.) Low, Normal and High Chromaticity (0.75 ma/bunch) Normal Chromaticity = 1.7 V, 1.2 H (nominal, uncalibrated units) Low V. Chromaticity = 1.2 V, 1.2 H (nominal, uncalibrated units) High V. Chromaticity = 2.2 V, 1.2 H (nominal, uncalibrated units) Low H. Chromaticity = 1.7 V, 0.7 H (nominal, uncalibrated units) Normal and High FB (0.75 ma/bunch) Normal FB = HFB = VFB = 20%, except at 1.0 ma when VFB = 30-35%. LFB Off. High FB = HFB = VFB = 40%. LFB Off. Precursor Bunch inserted 182 ns in front of train (0.75 ma/bunch) Plus a bonus Super-High Chromaticity run at 0.5 ma/bunch (by accident) Super-High Chromaticity = 5.5 V, 2.9 H (nominal, uncalibrated units)
