Why MINERvA?

• MINERvA is a compact, fully active neutrino
  detector designed to study neutrino-nucleus
  interactions with unprecedented detail
• The detector will be placed in the NuMI beam line
  upstream of the MINOS Near Detector
• MINERvA is unique in worldwide program
• The NuMI intensity provides
• Opportunity for precision neutrino interaction
  measurements
• Wide range of neutrino energies
• Detector with several different nuclear targets
  allows 1st study of neutrino nuclear effects
• Crucial input to future oscillation measurements
• Debbie, I stole this from Jeffs talk.change it
  all you want!

Basic Detector

• MINERvA proposes to build a low-risk detector
  with simple, well-understood technology
• Active core is segmented solid scintillator
• Tracking (including low momentum recoil protons)
• Particle identification
• Few ns timing (track direction, identify stopped
  K)
• Core surrounded by electromagnetic and
• hadronic calorimeters
• Photon (p0) hadron energy
• measurement
• MINOS Near Detector as muon catcher

• Active Target 30 fully active modules
• Downstream Calorimeter 10 modules, 2 active
• 9 Nuclear Target Modules
• One Module
• 2 scintillator planes
• 2 frames
• 2 steel plates
• (visiting whether one module should be broken
  into two pieces)

Overview of Work in Fund Types

• RD Includes all design work and prototyping
• Scintillator and fiber prototyping and testing
• Preliminary testing of 20 PMTs to determine
  necessary specifications for bulk purchase
• Two electronics DAQ systems for prototyping and
  testing PMTs
• One full module prototype
• Prototype frame, blah, blah and blah
• MIE Includes
• Blah
• Installation Integration Includes
• Installation in the MINOS detector hall since it
  impacts operation
• My brain has died.
