Draft of 3 year CMOS Strip Programme Need to advise WG3 on likely resource requirement Draft Outline provided at Valencia Discuss and improve basis for estimates in WG1
2
Four Phase Programme Resources and Deadlines Define programme and identify Resources Establish Group with strip tracker goal Break Point 1 Mid 2014 Group established, resources secured for Phase-1 Phase 0 now – mid 2014
3
Requirements – software and paper study for physics requirements on o the tracker layout, o physics hit rates, o noise hit rates, o trigger hit rates o radiation hardness requirements o acceptable dead area o efficiency requirements o radiation length limitations o requirements on assembly precision, survey Requirements – hardware restrictions o Power consumption o Uniformity of cooling o Flatness of sensors o Data rates Architecture & Mechanics o Architecture to focus on selected o Upgrade path to advanced architectures defined o Impact on module and macro assembly understood o Impact on mechanics optimisation understood o Sensor thickness selected on mechanical grounds Phase 1 mid-2014 to mid-2015
4
Sensor & Readout o Relevant foundries selected o HR and HV CMOS processes evaluated with basic devices. o Bulk and Surface Radiation hardness evaluated o Hit efficiency evaluated with representative devices, within a pixel o Charge collection efficiency understood, or close to o S/N S/T measured to be acceptable o Boundary electronics architecture understood o Cut lines, stitching, multi-reticule possibilities evaluated. o Common read-out selected Administrative o Re-evaluation of schedule, resource requirements and programme time scales o External review Phase 1 mid-2014 to mid-2015
5
Resource Requirement The phase 1 resource can be mostly staff as test structures exist and new ones can be part of multi-project runs. 2 FTE engineer equivalent. Sensor design & read-out and interface card design/test 2 FTE evaluation and test ? FTE software ½ FTE admin/organisation 60kCHF submissions and components for test equipment. 20kCHF travel Phase 1 mid-2014 to mid-2015 Break Point 2 Mid 2015 – basic technology demonstrated to be acceptable Foundries selected, architecture selected Layout and performance found to be compatible Requirements Established Resources for phase-II identified
6
Phase – II Mid-2015 to mid 2016 Sensor Large scale sensor with close to full functionality fabricated o Large scale sensor with close to full functionality fabricated o Bulk and Surface Radiation hardness evaluated o Hit efficiency evaluated including, within a pixel o Charge collection efficiency understood o S/N S/T measured to be acceptable o Boundary electronics architecture tested o Design of digital encoding periphery completed* o Test structure for digital encoding fabricated and tested * Mechanics o Any substantive changes required in mechanics evaluated o Test parts fabricate for any essential new elements o Consideration given to service module alterations. o Service tapes redesigned to accommodate new module configurations ABCn’ o ABCn’ designed and test chips fabricated in multi-user run o Consideration started of digital encoded version of ABCn’’ * Administrative o Re-evaluation of schedule, resource requirements and programme time scales o External Review o Secure Resources for phase III
7
Break Point III mid-2016large scale device demonstrated ABCn’ designed and fabricated Resources required for phase-III secured Resource Requirements 2 FTE engineer equivalent. Sensor design & read-out and interface card design/test 2 FTE evaluation and test ½ FTE on mechanical considerations. ½ FTE admin/organisation 500kCHF submissions and components for test equipment. 30kCHF travel Phase – II Mid-2015 to mid 2016
8
Phase III Mid 2016 – Mid 2017 ABCn’ o Tested with sensor prototypes from phase II o Fabricated in significant quantities o ABCn’’ designed and fabricated in multi-user run Sensor o Full scale sensors designed and fabricated o Sensors fully characterised o Sensors and ABCn’’ operated in module-like configuration o Digital encoded sensor fabricated* o >1 module operated together on a service tape Mechanics o Changes to accommodate new layout and stave/petal designed o Assembly protocols and series production planning considered Administrative o Planning for decision to adopt CMOS sensors in preference to planar o Mechanical, schedule implications evaluated o Costs fully evaluated o Programme review
9
Resource Requirements 2 FTE engineer equivalent. Sensor design & read-out and interface card design/test 2 FTE evaluation and test 2 FTE on mechanical considerations. ½ FTE admin/organisation 600kCHF submissions and components for test equipment. 40kCHF travel Phase III Mid 2016 – Mid 2017 Break Point IIIDemonstrated multi-sensor test structure Advanced planning for mechanical changes required Understood resource & schedule implications
