  2. APEX Run-7 • Regularly scheduled • Uptime ~60-70 % • Review activity  AEAC spreadsheet • Last 3 sessions: request vs. available time • Another AEAC meeting suggested

  3. Tomorrow APEX • BBA – 2h to wrap up – injection • Chrom feedback – take data – injection – 1h - both • Reproducibility 1h injection+ramp+store • Tune, orbit, chrom drifts – injection + ramp – 1h • IBS lattice – ramps+store (leads) – 3h • AC dipole – injections – gradient – 1h • Near integer WP – 2h at injection

  4. End of the run • IBS lattice development 12 h • Stochastic cooling 2h • Tune, orbit, chromaticity drift 2h • Main PS –common noise feedback 1h • IBS measurements 2 h • Beta* squeeze 4h • Chromaticity feedback 6h • BBLR 3h • Nonlinear chromaticity 2h • Transition instability 2h • Skew chromaticity 3h • Tune modulation LF Schottky 2h • Repeatability 3h • Energy loss 70 GeV 4h • Au 77 2h • TOTAL REQUESTS 50h • MAX AVAILABLE 35h

  5. June 6(low energy run or maintenance) • Chrom feedback - test ramps – 2h • Stochastic cooling – store – 6 bunches – 2h • Beta* squeeze – 4h • Transition instability - ramps – 2h • Skew chromaticity – store – 3h • Tune modulation LF Schottky – store – 2h • Repeatability injection+ramp+store 1h June 13(low energy run or maintenance) • IBS lattice – 4h • Chrom feedback (test of feedback) • Main PS –common noise feedback 1h – blue • Au 77 - measure emittance with gas-jet – 1h • Nonlinear chromaticity – 2h • Energy loss 70 GeV - 3h – ramp development (possibly more) • Repeatability 1h injection+ramp+store June 20 • Repeat 1h injection+ramp+store • BBLR – 3 h store
