## 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

- Bottom B/C Scint

- Central Trigger Scint (A- )

- PDTs

- Forward
- Trigger Scint
- (Pixels)

- Forward
- Tracker (MDTs)

- Shielding

## Tracking System Overview

***All detectors in this volume use ******SVX II****** readout***

- ~0.5 m

- ~1.3 m

## 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**

## 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**

## 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**** **

## Summary of Fermilab Technical Resources 

## 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:**

## 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 **
