Nuclear Emulsion Analysis Methods of Locating Neutrino Interactions
- Minnesota U.
The Fermilab experiment 872 (DONUT) was the first to directly observe tau neutrinos in the charged current interactionV$$\tau$$+N →$$\tau$$ +X. The observation was made using a hybrid emulsion-spectrometer detector to identify the signature kink or trident decay of the tau particle. Although nuclear emulsion has the benefit of sub-micron resolution, its use incorporates difficulties such as significant distortions and a high density of data resulting from its continuously active state. Finding events and achieving sub-micron resolution in emulsion requires a multi-pronged strategy of tracking and vertex location to deal with these inherent difficulties. By applying the methods developed in this thesis, event location efficiency can be improved from a value of 58% to 87%.
