OPERA electron neutrino event 226395185

Description

This OPERA detector event is a electron neutrino interaction with the lead target. The event data consist of Electronic Detector files (such as Drift Tube, RPC, and Target Tracker files) and Emulsion Detector files (such as Tracks and Vertex files). For more information, see the description of the whole dataset.
