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

LHCC – 1 July, 2008

Meeting.

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?


Meeting.

Layout Overview

Barrel Length: 240 Cm (Full length) 12 sensors/side.

Discs: 5 Discs / Side. Need optimization.


Meeting.

Layout Overview (4+3+2) Fixed Length.


Meeting.

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.

Meeting.

Schedule Overview (Preliminary)

Ready for beam December ‘17

Tracker Installation February ‘17

Tracker Ready for installation (Testing) July ‘16

Barrel Installation in the Support Tube January ‘16

EC Installation in the Support Tube April ‘16

Stave installation start June ‘14

Support Structure ready for installation January ‘14Start services installation

EC Stave Production starts June ’13

Barrel Stave Assembly starts January ’13 Readout Electronics and Stave components ready for assembly at

this time.

Conclusions


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.
