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?

5
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

6
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

7
Technical Integration Near-Term Effort

• Technical Coordinator has assembled small group
  which is being asked to develop a collective
  understanding of the successes weve 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!

8
Technical IntegrationNear-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 effortand that of integration in
  general
• Information will be used in a manner that will
  best benefit the experiment as a whole
• Reception weve 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 youwant to
talk with us - we need input!

Our Initial Reactions

• After 11 discussions thus far, each gt2 hours,
  weve 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

10
Our Initial Reactions

• However, there are still serious challenges that
  remain
• I prefer not to elucidate here theyve 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

11
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

12
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 weve had a
  bit more time
• In all cases we will need help, some of it
  experienced
• You may be called upon!

13
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

  formatting, clustering and track finding, Monte
  Carlo, TRIGSIM,
• Outline of resources, timelines, sequence of
  events
• Includes both project and non-project personnel
• Will be convened for 1.5-2 years, give periodic
  updates to collaboration
• Will be guided assisted by
• Technical Coordinator
• Upgrade Project Manager
• Algorithms Coordinator
• Information will be used to inform spokespersons
  on timing and resource needs associated with
  upgrade installation
• Will be in place by end March first update at
  Fresno

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
