The NuMI/MINOS Experiment

I participate in a search for neutrino flavor oscillations being conducted at the Fermi National Accelerator Laboratory. A new beam line, called the "Neutrinos at the Main Injector" (NuMI) will deliver an intense source of neutrinos to the experiment called MINOS ("Main Injector Neutrino Oscillation Search"), located 735km away in northern Minnesota.

    UT Efforts on NuMI

    My students and I have been contributing to various aspects of the NuMI neutrino beam design and construction. Some of our efforts include:
  • I serve as the co-convenor of the NuMI Beam Systematics Analysis Group which is responsible for estimating the beam neutrino flux and uncertainty.
  • We at UT built an array of ion chambers to monitor the secondary and tertiary hadron and muon beams.
  • We also built an array of secondary emission monitors to monitor the primary proton beam position and profile as it is transported from the Main Injector to the NuMI target.
  • We used to work on a focusing device for the secondary pion beam, referred to as the hadron hose. This project, initially approved, was subsequently cancelled due to budget constraints.
  • NuMI conducted its first test of the primary proton beam on Dec. 3-4, 2004. Our chambers were used to bring up the beam line and center it on the beam dump.
