Installation and Commissioning of the D0 Detector Jon Kotcher Brookhaven National Laboratory D0 Collaboration Director’s Review Fermilab December 7-8, 1999
Outline • D0 Upgrade Organization • Run 2 Detector • Installation: • Overall Approach • Current Status • Sequence: putting experiment together • Commissioning Progress & Plans • Manpower Discussion • Conclusions
Organizational Overview • Developing integrated approach to installation and commissioning • intimately linked, natural way to approach it • facilitates establishing priorities, decision making, related to: • spatial considerations, interferences • availability of detectors, components, resources • order in which things are done • One person overseeing both operations at managerial level • physicists, project engineers responsible for individual inst/comm sub-tasks (commissioning, tracker installation, mechanical/electrical infrastructure) • sub-projects remain primary players in installation/commissioning of their individual sub-systems • detailed plan for their sub-detectors developed by them
Muon Detector Upgrade Central Trigger Scint (A-f) PDTs Forward Trigger Scint (Pixels) Shielding Forward Tracker (MDTs) Bottom B/C Scint
Tracking System Overview Fiber Tracker Silicon Microstrip Tracker Forward Preshower Solenoid Central Preshower ~0.5 m ~1.3 m All detectors in this volume use SVX II readout
Installation Approach • Installation is integrated part of each sub-project: • sub-detector design takes into account installation constraints, interferences, end game scenario • designs developed from extensive discussions between groups • A- counter design based on detailed survey measurements • design of forward pixels/MDTs in part driven by proximity to end iron • FPS modular design motivated by installation/repair/access concerns • CFT connector design developed within very tight spatial constraints • Evolution of installation plan, activities in Assembly Hall, discussed in weekly meeting amongst principals • More specific, detailed issues discussed in sub-project or other integration meetings • Silicon, Fiber Tracker, Tracker Integration and Installation, ...
Installation Approach (cont’d) • Installation of detector is spatially very tightly constrained • DØ is highly hermetic, sub-detectors very closely nested • Ways in which it can be assembled very limited • Choreography very well understood • done before by many of the same people (Level 2 sub-project managers and other physicists, technical staff) • collaboration has experience bringing complex detector system online quickly, efficiently • immediately started taking physics data upon roll-in for Run I with no engineering run • Appreciate complexity of Run 2 system, concomitant demands on planning and execution
Solenoid & Field Mapper in Bore of Central Calorimeter • Precision mapping of field Summer 1999 • Analysis ongoing
Installation Status • Solenoid • installed, tested, mapped • Central preshower • installed with solenoid • Central muon system • All 630 A- counters installed (top and sides) • 224 cosmic cap scintillation counters, 118/120 new cosmic bottom • 94 PDTs - 18 A-layer, all B-and C-layers (38 each) • Level 1 trigger framework • installed, commissioned for 1st users These are final systems - not prototypes. In place, being commissioned
Routing of Clear Fiber Waveguides • Signals from Fiber Tracker, Preshowers routed via ~ 10m clear fiber waveguides to VLPCs below platform • Details of routing predetermined, mocked for verification Face of Central Calorimeter
Commissioning Progress and Plans • Assembly Hall: • Online system: • primary commissioning tool • EXAMINE, control/monitoring frameworks written • routinely exercised by experts, functionality being integrated, using Central Muon and Calorimeter crates • talk by S.

Comments on Installation and Commissioning Schedule • Historically, money and manpower for installation and commissioning embedded in individual sub-projects • accounted for in resource loading • Developing an independent installation and commissioning schedule • extracts relevant installation and commissioning tasks from sub-projects • includes those on boundary between sub-projects (i.e., Assembly Hall infrastructure) • information being updated, better organized • addresses need of obtaining overview of end game • mechanics of resource loading remain unchanged • information on individual sub-projects provided by those sub-project managers
Comments on Installation and Commissioning Schedule • Resource loading of the schedule continues to mature, evolve • We are profitably using this tool to help ourselves and the Laboratory • Are working on verifying manpower requests, using resource loading, by January • In general, we consider the commissioning to be driven by physicists, installation by technical manpower
Technician Manpower Fiber Tracker Installation of VLPC cryogenics VLPC cassette production Detector installed Xmas Waveguide hookup • Blue = all tasks in current schedule, including installation and commissioning • Maroon = installation and commissioningtasks only • Tech effort is sum of Fermilab Mechanical and Electrical Technicians working on Fiber Tracker (MTF112 + ETF112)
Technician Manpower Forward Muon Dressing of trusses, shielding Octant production continues Begin detector installation Xmas Detector installation, hookup • Blue = all tasks in current schedule, including installation and commissioning • Maroon = installation and commissioningtasks only • Tech effort is sum of Fermilab Mechanical and Electrical Technicians working on Forward Muon Detectors (WBS130, 132, 133, 134)
Technician Manpower Silicon Tracker Installation of silicon services Detector installed Xmas Silicon hookup • Blue = all tasks in current schedule, including installation and commissioning • Maroon = installation and commissioningtasks only • Tech effort is sum of Fermilab Mechanical and Electrical Technicians working on Silicon Detector (MTF111 + ETF111)
Technician Manpower = Head count + open reqs = Head count from Org Chart (no open reqs) Fermilab Mechanical Technicians = Head count from Org Chart (1 open req not incl) Fermilab Electrical Technicians Sum of Electrical and Mechanical (all tasks in blue) = Head count Xmas
Physicist Manpower for Installation and Commissioning • Sum of Fermilab and Non-Fermilab physicists in all tasks, and installation and commissioning tasks, in schedule • Roll off at end is not realistic - resource loading for physicists does not accurately reflect needs of project • Physicist manpower expected by sub-project managers to contribute during commissioning is far more in line with anticipated needs
Comments on Manpower Needs • Additional manpower is needed to keep installation on track: • Mechanical Infrastructure • gas systems, silicon cooling, tracking purge systems • Cabling needs • Forward Muon Installation • Needed most right now, with emphasis on next 6-8 months • possible relief, probable in some areas, but only following ramp-down of detector production (late Spring, 2000) • some technical manpower is not mutable • Estimates based on reconsideration of needs specific to installation and commissioning • Believe our estimates are accurate enough to start filling holes • lead-time matters here
Manpower Needs for Installation and Commissioning • Technicians: • Mechanical Infrastructure: • 4 Mech. Tech. • 1 Lead Tech. • Cabling in Assembly Hall: • 2 Mech. Tech. • Forward Muon Installation: • 3-4 Mech. Tech. • Total additional needed now: 9-10 MT, 1 Lead Tech. • Supervisory staff exists at DO • Mechanical Engineers: • Mechanical Infrastructure: • 2 Mech. Eng. • Forward Muon Installation • 1 Mech. Eng. • Total additional needed now: 3 ME • Designers: • Mechanical Infrastructure • 1 Des. • Total additional needed now: 1 Des. • Misc: • 35w Welder, 10w Plant Maintenance
Conclusions • New organization in place, clear partition of critical tasks • Reflects an integrated approach to installation and commissioning • Will become primary focus of entire experiment, strong core organization in place • Much progress in Assembly Hall to date: • Installation: Central Muon, Solenoid, Central Preshower • Commissioning: DAQ/online, Level 1 trigger, readout of CAL, Muon, Silicon Front-End • …and in outlying production laboratories: • Silicon 10% test, Cosmic Ray Test, testing of Forward Muon detectors • Installation sequence well-understood • the few new wrinkles are being integrated • could use more uninterrupted commissioning time during end game, working on this
Conclusions • Need to start filling positions now in order to prevent near-term installation from pacing schedule • Additional technical manpower could be used to advantage immediately • Collaboration takes March 1, 2001 deadline very seriously • Details related to end game developing, will evolve continuously until Run 2 (as they should!) • Collaboration’s focus increasingly shifting toward tasks related to final assembly, commissioning • We are as (more!) eager to start Run 2 physics as anyone, and are wholly committed to delivering physics-ready detector on schedule
