  1. TTF2-s2e ASTRA-Generator  GAUSS200000_Q1P0nCXYrms0P75mm4p4ps.ini ASTRA TTF2_09APR05_ACC1m9deg_200K.1350.001 mcad: “00_astra_to_bc1_in”  before_bc1_9deg.fmt1 CSRtrack end_10000.fmt3 mcad: “05_fmt3_to_astra”  x_9deg.ini ASTRA x_9deg.out mcad: “06_astra_to_bc2_in”  before_bc2_9deg.fmt1 CSRtrack end_10000.fmt3 mcad: “07_fmt3_to_astra”  y_9deg.ini ASTRA y_9deg.out mcad: add wakes GENESIS 3 particle formats (serial) ASTRA runs ~ 0.5 d + 0.5d +0.75d (1d) CSRtrack ~ 1h + 2h

  2. ASTRA differences between serial- and MPI-version  use serial version convergence tests missing; so far: Nrad=10, Nlong_in=15 for GUN & ACC1 Nrad=30, Nlong_in=300 for the rest CSRtrack 1d-method: 1-ASTRA particle  1-CSRtrack particle new filter technique: position averaging + sub-bunch (as before)

  3. z z 1d filtering in CSRtrack distribution of equi-charged particles: M-particle position averaging: & convolution with Gaussian sub-bunch with rms-length =  … …

  4. 200000 particles

  5. M = 10000  = 1 µm

  6. BC2 BC3 10 5 3 1 sub-bunch length

  7. after BCs: centroid extraction proposed by E. Schneidmiller offset of slice with peak current ASTRA: monopole charge density  SC effects underestimated to avoid that: shift centroids to center
