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 simulation verification
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 atomosphere at these energies,
so a tau signature such as a double pulse would be strong evidence of cosmological origin.
Alabama is developing an algorithm to identify double pulse waveforms online. The
algorithm will eventually be implemented in the online optical follow-up.
