  1. LEIR results 2012 and 2013 Summary Michael Bodendorfer June 30th, 2013 With the support of: M.E. Angoletta, G. Arduini, C. Carli, A. Findlay, P. Freyermuth,S. Hancock, S. Jackson, D. Manglunki, S. Pasinelli, SPS operators

  2. Continuous electron cooling RF capture @ 1780ms Up to 50% loss 2012: 208Pb54+ LEIR NOMINAL cycle (Qh=1.82; Qv=2.72) Extraction @ 2880ms (Master timer) Magnetic ramp start @ 1823ms 7 injections. First at 215ms, then spaced 200ms. 200μs long. B-field Intensity in 1010 charges vs. cycle time: 0 to 3.6s

  3. LEIR: Extracted intensity (Pb54+) per bunch 22.1.2013: S. Hancock lover εlong 29.11.2012 A. Findlay: Frevcorr Pb54+/bunch Goal (4.5E8/bunch) 23.11.2012: R. Scrivens discovers T2-phase effect Extensive RF MD by M.E. Angoletta CVORB change SPS Ops use Frevcorr Xmas Tech stop LEIR stand-by

  4. 23.11.2012: Tank2 phase 65°71° 2012: While LINAC3 intensity remains the “same”

  5. 2012: Reduction of momentum spread FWHM = 15kHz FWHM = 27kHz 65° 71°

  6. 2013: Chromaticity
