Description
The Long Baseline Neutrino Experiment will study neutrino oscillation and leptonic CP-violation using a high-intensity muon neutrino beam produced at Fermilab and detected in the Homestake mine in South Dakota. The collaboration is evaluating both 100 kton-scale water Cherenkov detectors and 17 kton-scale liquid argon time projection chambers as neutrino detectors. As part of the water Cherenkov design effort, the single photon performance is being evaluated for R7081 10" high quantum efficiency and R11780 12" standard quantum efficiency photomultiplier tubes manufactured by Hamamatsu Photonics. In this talk, we will describe a PMT characterization procedure that uses a triggered low intensity Cherenkov light source, and we will present single photoelectron charge distributions and transit time distributions for both PMT types. We will also describe efforts to statistically model the charge distribution and understand the relation between late pulsing and charge amplification behavior.
