Freddy Poirier reported “DFS Studies on the Main Linac with Rnd-walk-like motion“ (see slides on the web page)
Emittacne growth is dominantly from cavity wakefield in the case of large random walk parameter.
Q: What does energy corrected emittance mean?
A: Emittance after the linear correlation with energy (linear dispersion) is subtracted.
C: Modified version of alignment model will be made soon by Kubo. But we still need input from experts, including realistic parameters.
Javier Resta Lopez reported “Placed based start-to-end simulations for the ILC with Intra-train FB system”. (see slides on the web page)
Q: Which wakefield was used? TESLA-TDR?
A: Newly calculated one. Different from the old TESLA wake. Should be checked for detail.
Q: Why the equilibrium luminosity is so small compare with the design luminosity?
A/C: The tuning may not be good enough.
Kiyoshi Kubo showed a rough plan of parallel sessions in GDE meeting at FNAL.
