Our History

• DART -
• Scalable, portable, flexible
• Collaborative Effort with Collective Experiments
• Delivered System
• Run II
• Experiment Specific
• Collaborative effort with individual experiments
  (CDF/D0)
• Delivering Components

Our Philosophy

• Constraints
• DA Central Support Staff not growing
• Experiment lifetimes are longer - 10 years
• Funding is ever tighter
• Ideology
• Collaborate with talent found in collaboration
• Provide central development and support team
• Reuse - adapt/adopt
• Distribute knowledge
• Enforce standards

ODE Introduction

• Working with next generation experiments
• Evaluating new technologies
• Initially building on pre-built components
• Establishing test stand framework
• Heading toward final DA

What Next

• We have a sound philosophy with which to move
  forward to support the next generation of
  experiments at Fermilab.
• A lot of interesting work ahead to deploy the
  tools that we are evaluating in a production test
  stand this spring.
• We are in a position to use our experience with
  test stands to start the architecture and design
  work for the final Das in collaboration with the
  experiments.
