**Run IIb Project & Run Coordination **

**+ Data quality (Diehl), which does not presently have formal organization associated with it.  Requires integration with other lines of mgmnt.  Approach being considered, evaluated.**

## Description of Technical Integration

**Evolution of detector improvements & associated resources must be optimized as a whole**
**Elevate, focus and enhance data quality effort **
**Tie more intimately to online operations, accelerate feedback to/from rest of experiment**
**Resources (& especially expertise) associated with IIa & IIb efforts are largely common.  Priorities need to be set:**
**Commissioning of remaining Run IIa systems must be completed, and ****its impact on operations minimized, managed**
**Detector maintenance must continue unabated**
**Maintain pace on finalizing IIb designs, continued fabrication**
**Preparation & realization of smooth integration of IIb systems into running experiment**
**Establish integration of detector efforts with other experimental functions (i.e., physics, algorithms, software & computing)**
**Where are our current measurements limited by the hardware?**

## Overview of Run II Considerations

**Name of the game is different than in the past:  accumulation of integrated luminosity paramount**
**Push data quality effort as far upstream in the data-taking as possible – save time, effort**
**Detector improvements, upgrades must be introduced as machine evolves**
**These enhancements have to be phased in and commissioned as seamlessly as possible**
**e.g., trigger must evolve with the run, both before and after Run IIb upgrades**
**Adequate planning, integration (and manpower) is absolutely critical for achieving this**
**Work associated with acquiring data and producing physics must continue unabated**
**Challenging, to be sure, and constraints are unique for us, but with the proper commitment, it is surmountable **

## Overview of Detector Evolution for Run II

**For current operations, these improvements have to be carefully pre-planned and phased in**
**STT, FPD, other trigger evolution (all levels), releases, etc.**
**There has been, and continues to be, much discussion within the upgrade project about installation and commissioning of systems**
**Sensitivity, awareness is there – taken very seriously**
**Has helped precipitate consideration of some crucial design changes that enhance system “commissionability”**
**For example, see talk by Meenakshi Narain on CTT upgrade, Wed plenary**
**Other systems continually develop plan with an eye toward minimizing interruption of data taking**
**Upgrade Installation-to-Physics Task Force:**
**Provide outline of resources, timelines, sequence of events required for installation, technical commissioning, and physics commissioning of upgrades **
**Will report to spokespersons, be guided & assisted by Technical Coordinator, Upgrade Project Manager, and Algorithms Coordinator**
**Will be in place by end March – first update at Fresno**

## Technical Integration:  Near-Term Effort

**Technical Coordinator has assembled small group which is being asked to develop a collective understanding of the successes we’ve had, and the nature of the problems yet to be solved**
**G. Ginther, G. Gutierrez, B. Klima, J. Kotcher**
**An “audit” of sorts**
**Will likely form initial nucleus of detector integration team**
**Fundamentally, we are trying to learn where our physics measurements are currently limited by the detector, and how to most effectively organize the hardware, data monitoring, and data quality efforts**
**Eye toward prioritizing outstanding work, and focusing/adding effort in the places they are needed most**
**Detector/hardware issues cannot be solved in isolation; single manpower pool!**

## Technical Integration:Near-Term Effort

**With this in mind, we have begun detailed discussions with individuals/groups, more will follow**
**Detector leaders, physics/ID convenors, individuals embedded in various quarters, etc.**
**In order to be effective, these discussions are crossing the major boundaries of the experiment**
**Spokespersons, Physics, Algorithms, Software & Computing and Technical Coordinator have discussed this, recognize the need, and all support the effort...and that of integration in general**
**Information will be used in a manner that will best benefit the experiment as a whole**
**Reception we’ve received so far has been very positive, and the frank discussions have been extremely valuable, & very much appreciated**
**Anticipate investing another few weeks in this – time very well spent**

**Others are urged to contact me if you****want to talk with us - we need input!**

## Our Initial Reactions

**After ~ 11 discussions thus far, each >2 hours, we’ve all come away extremely impressed:**
**Wealth of talent**
**Level of dedication and effort **
**Our younger colleagues are not only doing all the work, but leading significant efforts on all fronts as well**
**Quite extraordinary, even inspiring**
**Our thanks to all of them for committing to DZero at this level, and driving this experiment forward for all of us**
**Exciting and encouraging...**

## Our Initial Reactions

**However, there are still serious challenges that remain**
**I prefer not to elucidate here – they’ve been discussed enough lately, and I want to focus on the broader issues**
**Much effort is going in to solving fundamental underlying problems & laying groundwork for physics measurements, but we feel the collaboration can and must do more in these areas.  Balance is still not there, does not adequately reflect the needs of the physics, and we feel this must be addressed.**
**Our deepest thanks to everyone who is helping to tackle these problems – this essential and difficult work often goes unrecognized (this, too, should be addressed, but some other time...)**
**The Gang of Four has had many lengthy discussions about what needs to happen in order to attack this properly**

## Our Initial Reactions

**In order to try to accomplish in, say, one year what would otherwise be accomplished in two will require a significant change in the way we approach, and respond to, the management of the experiment **
**The impending turn-on of the LHC underscores the need for aggressive approach**
**Essentially, we believe a mechanism must exist that allows effort to be focused, prioritized to serve the experiment and its physics in a more targeted manner**
**Improvements of this kind cannot be made without help, active participation, and cooperation from all of us – students, post-docs, & senior membership**
**More specific appeal made to IB, senior colleagues yesterday evening  **
**Reception was good, in my estimation**
**But this only marks the beginning...**

## What is Becoming Clear...

**Group needs another few weeks to crystallize our thoughts, but a few of the pressing needs are clear:**
**More thorough, deeper understanding of calorimeter performance**
**Oversight of trigger development & integration, including anticipation of Run IIb**
**Appropriate scope and organization of data quality, how to push efforts upstream **
**Other issues also need to be addressed, but will be discussed with more clarity after we’ve had a bit more time**
**In all cases we will need help, some of it experienced**
**You may be called upon!**

## Conclusions

**Fact finding has been very useful for laying out the landscape for us, clarifying where we should put our effort**
**We hope those who have spoken with us have gotten something out of it as well**
**Another few weeks is needed – specific changes, approaches will follow**
**We call on everyone to work with management (including spokes) as we try to focus and direct effort to the places that we feel will most benefit the physics**

**Spares follow**

## A Personal Comment

**You will never hear the “s” word ****(“service work”)**** from me **
**The distinction itself is artificial: everything we are doing is integral to physics measurement**
**Making the distinction reinforces the stigma on fundamental work that we continue to suffer from **
**This work only increases in importance in large, technically demanding experiments**
