Milestones
End CE works: December 2010
Installation: 2011
Linac commissioning: 2012
Modifications PSB: shut-down 2012/13 (6 months)
Beam from PSB: 1rst of May 2013

Construction of LP-SPL and PS2 will not interfere with the regular operation of Linac4 + PSB for physics.
Similarly, beam commissioning of LP-SPL and PS2 will take place without interference with physics.
Milestones Project proposal: June 2011 Project start: January 2012 LP-SPL commissioning: mid-2015 PS2 commissioning: mid-2016 SPS commissioning: May 2017 Beam for physics: July 20173

Layout (4+3+2) Fixed Length Barrel
4 Pixel Layers: 1(2) b-layers “easily replaceable” inside a support tube. 3(2) Layers incorporated in the Fixed length Barrel.
Mechanical Support: Off the tube? Off the Barrel
3 Pixel Discs on the outside.
Internal Discs?

Layout Overview
Barrel Length: 240 Cm (Full length) 12 sensors/side.
Discs: 5 Discs / Side. Need optimization.

Disc Layout is still uncertain. We need to converge on a “baseline” by the time of the Nikhef meeting.
Solution with better coverage but more complicated from an Engineering point of view and more massive. - Need optimization.

Conclusions
8/12/2008 19David Lissuaer, Santa Cruz
Meeting.
Little feedback from Simulation to date!!We might not have significant feedback from physics analysis before final decisions will need to be made.
To stay on Schedule need to agree on a baseline (at least for the barrel) by the NIKEHF meeting.
Assembly on the surface has significant advantages. Might be the only solution that will allow installation of the detector in 18 month shut down.
Has serious schedule implications!!!Detector needs to be ready ~12-18 month earlier.
