SC Collaboration Meeting Date: Tuesday 20th and Wednesday 21st of May Invitation 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.

Educational Talk 2a Phase 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.
