  1. E-cloud Simulation Meeting Ecloud simulations for the LHC arcs Humberto Maury Cuna October 28th, 2011

  2. Outline • A bug in ECLOUD code – XY distribution for: • Field-free section • Quadrupole • Dipole • Oscillations in quadrupole heat load simulations.

  3. Field-free region – 7 TeV – 1.2x1011 – 25 ns

  4. Quadrupole – 7 TeV – 1.2x1011 – 25 ns

  5. Dipole – 7 TeV – 1.2x1011 – 25 ns

  6. Dipole – Gas ionization 0.54 T B = 0.01 T

  7. Oscillations in quadrupoleHeat load simulations • Simulationsparameters: • Macroparticles: 2500 • Time stepsinter bunchgap: 3000 • Energy: 7 TeV • Bunchspacing: 25 ns • Reflectivity: 0.5 • Ibend=2

  8. Results The “bug” seems to affect only dipoles and just the photoemission case. The quadrupoles heat load oscillations depends on the SEY and also the number of time steps.

  9. Thank you for your attention

  10. Quadrupole – ibend = 6
