24 Mark Woodley, SLAC5th ATF2 Project Meeting (December 19, 2007)24 still studying effects of far-off-axis extraction through QM7R.1 … may need to rematch EXT or change DR optics to compensate ambiguity remains in choice of locations for vertical dispersion correction skew quadrupoles (Okugi-san’s locations and mine) … determine from simulations which locations are most efficient Feedforward / Feedback / FONT kickers are not in the deck yet … need a design (30 cm striplines? FEATHER kickers?) other Feedforward / Feedback device locations? (maybe some specifics at this meeting … ) simulations with estimated multipole content of SLAC epoxy kickers, QM7R.1, BS1X, shimmed QC3s, … need to redo and expand full tuning simulations (especially with realistic errors in diagnostics) revisit fine-tuning of higher-order aberrations (à la Andre) need “small spot” optics for LW1X (1 µm) operation MPS issues for commissioning?
