Double bang flashes with IceCube

Astronomy and particle astrophysics with the IceCube Neutrino Observatory benefit from tau neutrino detection. Tau neutrinos produce distinct, nearly background free electromagnetic showers within the volume of IceCube. The search for tau neutrino extragalactic point sources requires accurate event reconstruction. Utilizing LED flashers within IceCube allows for the simulation and calibration of the detector for tau neutrino event reconstruction. The search for the classic double bang tau neutrino event geometry within existing flasher data provides only a few useful events for configuration. A Monte Carlo simulation shows a quadratic relationship between the number of actively flashing IceCube modules and the number of expected calibration events. Consequently, data with more active flashers should be collected to produce the events useful for tau neutrino event configuration.
