SC Collaboration MeetingSC Collaboration MeetingDate: Tuesday 20th and Wednesday 21st of MayInvitation only ~11!Preliminary Program:
- Status report for the PIC codes PTC-py_ORBIT, SYNERGIA and IMPACT.
- Report about results concerning the Giuliano benchmarking suite for the PIC codes covering all 9 steps.
- First results from the various investigations concerning noise in PIC codes and in particular for storage rings.
- Progress with the frozen space charge codes.
- How well do we understand the (2011-2013) PSB & PS experiments with simulations?
- Next plans for simulations for the CERN pre-accelerators and experiments planned for 2014.

Phase Advance and TunesPhase Advance and Tunes
• Tracking done for a FODO lattice with sextupoles including random component to create strong sextupole resonances to first order, in particular the Qx + 2 Qy = n coupled resonance.
• Non-linear only no space charge
• Tunes similar to the PS experiment Qx = 0.07 and Qy = 0.48.
• In the tracking just amplitudes are change in 4D.
