  1. Comparing Super-K to Hyper-K:Attenuation Length Karl Ahrendsen Buena Vista University Dr. Chris Walter and Dr. Kate Scholberg

  2. Outline • Super K -> Hyper K and why • My Project: Examining the attenuation length

  3. Super K(amiokaNDE) • Kamiokande-> Not big enough • More water = more chance to see proton decay • Super K’s Resume • Discovery of neutrino oscillation • Proton lifetime extension • Helped solve the solar neutrino problem

  4. Super K(amiokaNDE) • Kamiokande-> Not big enough • More water = more chance to see proton decay • Super K’s Resume • Discovery of neutrino oscillation • Proton lifetime extension • Helped solve the solar neutrino problem

  5. A Bigger Detector: Hyper-K Super K

  6. A Bigger Detector: Hyper-K

  7. A Bigger Detector: Hyper-K • 50 kT -> 1 MT • $750 Million • 11,000 in PMTs -> 99,000 in PMTs

  8. 63% L (q) 100% Light (Charge) Attenuation Length My Project: Comparing Super-K to Hyper-K

  9. A new way to measure distance • Hyper K still in infancy • From Crosstankto Average Distance d Hyper K

  10. A Lesson in Data Cuts • Cutting out background • Distance to wall • Angle to PMT • Time of Flight

  11. Applying the Cuts

  12. Applying the Cuts

  13. Attenuation Length Results

  14. Conclusion • Hyper-K is the next big thing in neutrino research • The Hyper-K simulation provides a similar attenuation length to Super-K.
