ofDØ RunIIb Silicon & Trigger Upgrades

Schedule & CostsR.P. Smith for

the DØ Collaboration

Action Items from July 2004 Review

Understand Clearances for Layer Zero (in 2004 Shutdown) Incorporate Physics Commissioning in Installation Plans and

Schedule Review Manpower Estimates, articulate needs for extra-DØ

help Provide analysis of Installation Risks

+ Incorporate new information from L0 and Trigger hardware development teams, 2004 Shutdown experience

2004 Shutdown Activities Related to Installation

Upgrade Installation “Infrastructure” tasks accomplished during 2004 Shutdown (in CH or MCH)

L1 Cal – None scheduled L1 CalTrack – begin mods of Muon PDT and Scintillator

FEB’s, terminate L1CTT transition and MTCxx cables L1CTT - install parallel “slice”: crate, controller, few DFEA’s,

cables for CTOC, CTT L2 Beta – None scheduled L2 STT – None scheduled L0 Silicon – L0 clearance survey, adapter card and 4-Hybrid

SVX4 string, N&S mini fuse panels, new Wiener PS, Interlock chassis

Online – Move Online (DAQ, Oracle, NFS) to new host cluster

Beam-Off Time Paced by Silicon

Present Installation Schedule shows Tevatron Shutdown Time driven by Layer Zero Silicon Installation

Detector Not Removed From Collision Hall 2004 Shutdown experiences verifying silicon clearance are

leading to reconsiderations of installation plans => Revising existing schedule!

Consideration of each installation step, appropriate (repeated) repositioning of End Calorimeter(s) and installation of precision fixturing, indicates L0 Installation requires 12 weeks.

Resume Tevatron operations in week 13 with opportunity to re-enter CH during L0 technical commissioning.

14th week required to close detector and make final survey Workweeks are standard 40 hours, five days Silicon installation dominates CH access time. Trigger

Elements require lesser amounts of CH access in time “shadow” of L0.

Installation Risk Analysis

Schedule Risks from Unanticipated Difficulties Encountered during L0 Installation: substantially ameliorated by

2004 shutdown clearance survey Experience with survey instruments in gaps Handling of EC’s and beampipe open-up/reclosing

Careful design of and practice with Installation Tooling beforehand Involve personnel with previous DØ SMT experience where possible No second shift or overtime work currently scheduled MSProject Installation Management Tool

Risk from Accidental Handling Damage to L0 during Installation: substantially ameliorated by

RunIIa Experience Will develop detailed step-by-step plans for every aspect of the

work Involve personnel with previous DØ SMT experience where possible No second shift or overtime work currently scheduled

See W. Cooper’s Talk


15


Schedule Risk from prolonged Commissioning of L1Cal: substantially ameliorated by

Careful “non-invasive” handling of fragile BLS cable installation (1280 coax cables under MCH1 floor, >15 years old)

Preparation of BLS/ADF “patch panels” to facilitate reconnection to new ADF’s

Test Site on DAB “Sidewalk” – full system to be operated using collider data input prior to shutdown

Test data at L2 and L3 thoroughly verified Operating software to be exercised


16


Schedule Risk from prolonged commissioning of L1CTT: substantially ameliorated by

“Parallel Chain Slice Test” installed in 2004 Shutdown to enable system level operation of real hardware (crate, crate controller, DFEA2’s)

Full test of system software (download, monitor, diagnose) Test that new hardware loaded with present doublet equations

gives identical results to current trigger Test/optimize (effic. vs rate) algorithms with real data

Schedule Risk from prolonged commissioning of L1CTM: substantially ameliorated by

“Single Button” running in global runs with real production CalTrack boards prior to shutdown


17

Conclusions

Installation Management Team in place SC-IPC up and running to monitor physics commissioning

planning and manpower scheduling Evolution of Schedule Continues

Tasks detailed to sixth sublevel Resources (Effort, M&S) loaded WBS Dictionary and BOE in place Timeline assumptions depend on availability of identified

personnel Schedule refinements underway as planning evolves

DØ prefers Tevatron shutdown that begins after all upgrade components are ready (to minimize integrated luminosity cost)
