UA General M&O (non-science) IceCube Responsibilities and Contributions:
The Alabama Group’s major responsibilities and contributions towards maintenance and operations of the IceCube experiment include:
· Primary institutional responsibility for overseeing flasher operations and software.
· Major responsibility for data quality verification.
· Major responsibility for calibration coordination
· Major responsibility for software coordination
Analysis: The main analysis focus at the University of Alabama is searching for the lowest energy tau neutrinos that are identifiable “double pulses”. At energies at and above 100 TeV, the “double bang” signature of a high energy tau neutrino becomes a double pulse in the IceCube waveform. There is no appreciable tau signal from the atmosphere at these energies, so a tau signature such as a double pulse would be strong evidence of cosmological origin. At lower energies, Alabama is undertaking a search for the appearance of atmospheric tau neutrinos from oscillation, which would manifest as an excess of cascade-like events.
Alabama is developing an algorithm to identify double pulse waveforms both online and offline. The online algorithm will eventually be implemented in the online optical follow-up. The offline tau search and the atmospheric appearance analysis require high quality cascade reconstruction, so Alabama is also working on single cascade reconstruction algorithms and calibration of cascades with flashers.
