Presentations of LCU meeting on upgrade studies on 17/10/2007
Various optics solutions for Phase I -> R. de Maria (pdf file)
Review of the optics studies for the four layouts (three from LHC PR 1008 and one from LHC PR 1000). A similar talk will be given at the next LIUWG.
All the data will be collected to make a final comparison between the various solutions in view of selecting the best one(s).
As already reported based on preliminary results, the MODULAR and COMPACT layouts are not performing up to the specs and will be discarded.
DA studies for the COMPACT layout -> M. Giovannozzi (pdf file)
Assessment of dynamic aperture for COMPACT layout.
Specifications are exceeded even without nonlinear correctors.
Additionally: check of DA dependence on magnet aperture (FQ depends on magnet aperture).
Weak dependence on Q1 aperture. Strong dependence on Q2 and Q3 aperture.
